OH TX 67
===

[00:00:00] Kaisha: Oh, Brian, how's it. Growing friends. Welcome to office hours. Your source for free cannabis cultivation education. My name is Kaisha and I am co moderating side-by-side with my good friend, Mandy WhatsApp.

[00:00:11] Mandy: Hey, Kaisha. Hey everyone. We're here for episode 67, also going live over on YouTube. So if you're logging on over there, make sure you send us your questions and I'll make sure I get those to the team.

[00:00:22] Mandy: Make sure you're also following us on all the social medias. So we're on Instagram, Tik, TOK, YouTube, LinkedIn, and social club. [00:00:30] Let's not forget why we're here though. We got y'all's crops hearing questions in this week, so let's get right to it. I'll pass it back to you, Kaisha.

[00:00:36] Kaisha: Thank you, Mandy. All right. If you're live with us here and you have a question type it in the chat at any time, and if your question gets picked, we'll have you either unmute yourself or one of us will ask for you, Jason is on the road this week. So it's just as a new staff. How are you doing?

[00:00:49] Kaisha: Good. Doing good. Good. Good to see you. All right. So you had a walkthrough. You wanted to start the show with yeah. You want to,

[00:00:57] Seth: yeah. Yeah. You know, we get a lot of questions about our [00:01:00] irrigation integration and I thought it'd be a good time to just kind of walk through a. How to set up your open sprinkler with the Roy.

[00:01:06] Seth: Cause it's pretty simple.

[00:01:08] Seth: Basically. In the beginning of this process, you want to go navigate to your setup menu. Like over two devices and then tab over two controllers here. And then basically you're going to click on this device.

[00:01:25] Seth: That's going to give you if it's already hooked up all of your zoning options, but you [00:01:30] add in your controller, we'll go in here. Type in your IP address. Your port number password, your stock password I'm most open sprinklers is open door. So if it's brand new, that's helpful. Right here. I just choose which gateway that is on the same local area networks. So if you have a bigger facility or multiple networks for different areas of the facility,

[00:01:50] Seth: Make sure you're on the same local network. And then give your device a name. After it's connected. You'll have confirmation here. You'll see how many channels you have connected. If you have an [00:02:00] expansion zone, that'll be reflected here. And then you'll have access to this menu in which you can set a room for each zone.

[00:02:09] Seth: Are each a. And then the zone in that room that ports attached to. Then you've also got the option to set a master zone. Usually that kind of corresponds to a pump control or a master valve control for the room. In this case here, I don't have that. I just have a relay controlling the pump because I only have one irrigation zone, but you can expand this [00:02:30] out.

[00:02:31] Seth: I believe up to 72 zones total, and then you can also choose to run in sequence or once. I will warn people though. Typically open sprinkler does not like to run eight zones all at once. You're onto a voltage issue. So in sequence, and if you have a big room, you're running them in sequence anyways, because you can only irrigate so much at a time.

[00:02:49] Seth: Now to find your irrigation schedules, she'll go to your room dashboard.

[00:02:55] Seth: And then on the right-hand side, we've now got the irrigation button. Once an open [00:03:00] sprinkler is tied to this room.

[00:03:03] Seth: If I go in here, I can ask it, access my harvest group schedules. I don't have any harvest group schedules going right now. But I do have a room schedule. If I go here and click the schedule. You can see. A basic. I've got to turning on at 10:00 AM because the lights on it, eight, three minutes, four times repeat after every 30 minutes.

[00:03:22] Seth: Here it is represented throughout my day. 12 hours cycle. And then if I had just made this I'd hit review and save. [00:03:30] You go down here. And to start that irrigation cycle, I'd go ahead and hit resume right here. Which will activate it in the room. Or if I want to turn it off, I would go ahead and hit odds.

[00:03:42] Seth: And then to establish. A spot watering. Basically, I'd go to new room schedule here and say new irrigation. I want to put on zone one. That's my own. These

[00:03:54] Seth: I would hit next. And let's say, I typically want to spot water at if my lights [00:04:00] turn on at six. These kind of aid, Anna. Typically want a spot where let's say 10 30, if I haven't reached field capacity. So I'd go in and say, all right.

[00:04:10] Seth: At 10 30.

[00:04:13] Seth: I want. Singular. Five minutes.

[00:04:20] Seth: Watering event to happen.

[00:04:29] Seth: Go ahead and save [00:04:30] that. And then when I want to turn that on, I'd go in here. At play or resume, that's going to turn on that spot water schedule. And then remember that each of these schedules is running daily. So, if you want to run just a spot watering, wait till after that spot waterings done and then turn it off for the day. That way it doesn't accidentally roll into tomorrow.

[00:04:50] Seth: And what's cool about this. As you can attach these irrigations. You're engaged in templates to your harvest schedules. And when you've done that, now you have this in here, so you have a baseline. And when you need to go in and [00:05:00] change duration or add events, it's as simple as clicking on the, a little icon over here.

[00:05:05] Seth: Popping up this menu. And configuring either a different, you know, more irrigations on your P. Or. Potentially adding a P two. If at the end of your P one, you wanted an irrigation that was different than your other P one irrigations. So a lot of flexibility a little bit easier to use in the open sprinkler UI.

[00:05:23] Seth: And very intuitive. And I just wanted to go over that because I've been noticing more and more people getting excited about. [00:05:30]

[00:05:30] Kaisha: So glad you gave us that overview said that was a good reminder for folks out there. We did debut this feature, not that long ago, but you know, some of our clients that there might be kind of missing out, maybe they're not aware of it. So maybe what's one of the key things that. Clients who are not using this right now, what are they missing out on?

[00:05:46] Seth: Just easy irrigation, all in one platform. You know, most of us are using either open sprinkler troll master or. A small variety of other irrigation controllers and all of them have a different performing or programming. Platform to go into. [00:06:00] So rather than going like, all right, this is what I need to accomplish on my chart. Let me open my open sprinkler app on my phone program that separately. Now I can do it all in one dashboard.

[00:06:09] Seth: And the other thing it does too, as a void, especially for some facilities that may not have the most elaborate, you know, digital security system. No longer having to port forward gear, open sprinkler out. To get access to it. Now you can access it directly through your riot gateway. And you're open sprinkler connection stays at your local area network. So no reason to put yourself as security data security risk [00:06:30] anyways.

[00:06:32] Kaisha: Excellent. Thank you for that fast. So clients, if you're not using open sprinkler, they. They are a new Oakland sprinkler integration you might want to get on that. Make your lives a little easier. All right, let's get down to the questions, Mandy. What's going on YouTube.

[00:06:46] Mandy: Yeah, thanks everyone over there for sending me your questions. We're going to start with John's. John wants to know.

[00:06:52] Mandy: What are the most important steps to dialing in the lighting for a grow when you're working with multiple LEDs of different brands that you've pieced together [00:07:00] over time, each plant has about a hundred Watts.

[00:07:04] Seth: Gotcha. I mean, I think the first step is to go get yourself a, you know, you don't have to break the bank to get some sort of par sensor.

[00:07:11] Seth: Trying to figure out what your, you know, how many micromoles of light we have coming in. And you don't necessarily need to do a DLI calculation in every life, but you need to go under each light and establish and. You have a hotspot, how much variation and. At what point, you know, also look at your CO2 in the room, see how much light you can actually push on these plants. But. [00:07:30]

[00:07:30] Seth: You know, since you have a bunch of different brands of lights, even if they're all a hundred, why you want to figure out what is the percentage setting on the dial to get each of these lights to match up and, or do I need to raise and lower certain lights to get my canopy lighting even. At the end of the day, just some basic sensing technology and then probably a lot of patients in a notepad to write down and make sure you remember which light has which little setting. Cause you're always going to be operating on a little bit of a differential between your fixtures.

[00:07:59] Mandy: Awesome. That's great [00:08:00] advice. Caesar wrote in. Why are so many commercial growers doing only nine untapped plants per light.

[00:08:08] Seth: Because when grown properly, that gives you a good balance of enough space in the canopy to get good light. Light and air penetration. You know, we don't want a candidate that doesn't have good air flow, we won't get good transportation. And then the other side of it is it completely like if we go to a point where there's almost no light getting through the canopy, that means our gradients pretty bad. Our bud quality in our top canopy, the steep.

[00:08:29] Seth: You know, [00:08:30] Right. In from the main canopy is going to be pretty good. The lower we go. The lower grade bud, we tend to get so typically a lot of guys, you know, A lot, but some people will push it all the way up to like 16 per light. And then overgrow it and ended up with plants that are a little too bushy.

[00:08:45] Seth: And then it's graded out at, let's say 30 to 40% a quality. 30 to 40% equality and then 20. To a little blood percent trim. Now if we can go to nine plants per year four by four, [00:09:00] we can open up the canopy, especially if you're nailing vege, transplant, everything tracking along nicely. You're gonna be able to fill out that canopy. And at nine, you're going to have less defoliation and pruning work.

[00:09:10] Seth: And then usually about the same yield and a greater quality index on your finished product. And it varies per grower. You know, if you can usually push a little more bulk biomass. If you're running a little higher plant numbers. But part of it is having the market to say, Hey, I've got the either, you know,

[00:09:28] Seth: Array of brand names. I can [00:09:30] put this other or different product types. That I can say, you know, Hey, I've got my 20 to 30% a grade but the rest goes into, you know, Joints edibles distillate, you know, Are part of the year growing and printing techniques are also optimizing your end output.

[00:09:46] Seth: The match your market.

[00:09:49] Mandy: Yeah. So a couple of considerations to keep in mind, but. Awesome. I believe that is it for the questions over on YouTube. So I'll pass it back to. Acacia for our questions from Instagram.

[00:09:59] Kaisha: Awesome. Thank [00:10:00] you so much, Mandy. Mikey, just posted here, Mike, if you want to unmute yourself, feel free.

[00:10:04] Kaisha: One one fourth to one third town, dry weight per plan at eight to nine per light has been doing really well for us. Yeah. Awesome. Okay, we're going to keep it moving. We got this call in from Urbach gab a few weeks ago. Weren't able to get through it until today. What should one do if CO2 continues to stack over a 12 flower sticks?

[00:10:28] Kaisha: Vege, our [00:10:30] period lights off cycle. Light's on, I'm running 800 through 1200 PPMS. While it stacks to over 2,500 to three K at

[00:10:38] Seth: night. I would probably look for a potential malfunction in the controller or find a controller that has a nighttime setting. So you can turn off your CO2 injection at night. It is basically once photosynthesis stops the plants, not uptaking any of that CO2 really.

[00:10:54] Seth: So that's just accumulating all night. And your sensor may not, or your controller may not be able to [00:11:00] effectively shut it off overnight is what it sounds like.

[00:11:06] Seth: And to keep those controls

[00:11:07] Kaisha: under

[00:11:08] Seth: control, huh? Yeah. And I will say to, you know, I've seen this problem happen to and vices that have like malfunctioning burners. Or typically something with the CO2 control system. Sometimes it's just the sensor it's drifted or it doesn't sense. Well, outside of a certain range,

[00:11:23] Seth: So the system's response is to responding correctly. When I can't accurately read the value. [00:11:30]

[00:11:30] Kaisha: All right. Or Barca. Good luck out there. Let us, man. How you doing? All right. Okay, moving on to the next one. Anthony submitted a question they wrote in after your first four shots and you reach field capacity. If you reach that within the first two to three hours, do you not water again until

[00:11:46] Seth: the next morning?

[00:11:48] Seth: So for looking at, you know, The time that the plant's going through a stretch. That's exactly what we want to do. Basically, you know, water over ideally at two hour last window, and then push that long dryback. [00:12:00] That's what's going to give us that generative node stacking that we're looking for. And then, you know, once that stretches done,

[00:12:06] Seth: I'm gonna flip over into bulking where we stretch that window out a little bit and then try to optimize our irrigation strategy to make sure all of our plants are receiving. Is close to the same care as possible.

[00:12:19] Seth: All about that

[00:12:20] Kaisha: uniformity. All right. Coming up next here from super cotton mouse. They vote in. Could you ask about converting bulk, easy to pour water ISI? I think [00:12:30] they're just kind of wondering how to do that.

[00:12:32] Seth: So, I mean, basically bulky sees what we're looking at in solution. Maybe they got bulk VDC or bulk round hockey. See, we're looking at a liquid solution.

[00:12:40] Seth: Pour water. You sees what we're seeing in the actual pores in the media. So there's not really, I mean, We could probably find a mathematic conversion to do that. The real way to do is to actually measure that poor water ISI. And if we're looking at it, poor water ISI would be the bulky. See that we're measuring in solution inside the substrate.[00:13:00]

[00:13:00] Seth: And at the end of the day, that's what we want to see is an actual comparison between what is our input ISI. What is our ISI in the media pores. What's going on there? You know, are we stacking salt up in there? Are we washing it out? And then looking at our runoff, you see, we can start to determine like, Hey, do we have any channeling going on? And then we're looking also at pH there to see, do we have any pH script happening and trying to analyze what's going on inside the plant?

[00:13:24] Seth: The reality is some of that runoff though, is like, we're looking at all poor. OTC. [00:13:30] In the runoff, we're just looking still at salinity. We're not actually evaluating what is running out of there. And that's where pH comes in to kind of tell us. Where we're at, as far as plant nutrition goes inside the roots.

[00:13:44] Seth: Everything really

[00:13:45] Kaisha: is connected. Isn't it. All right, sending it over to you, Mandy. What's happening on YouTube.

[00:13:50] Mandy: Yeah, Hector has a question. How much PPM of nitrogen and solution do you suggest. That I use so that it doesn't disturb flower [00:14:00] development. Also for ISI and substrate, does it have the same increase over time in the plant life cycle? Like DLI

[00:14:06] Seth: does.

[00:14:09] Seth: We're looking at nitrogen PPM. I mean, where to start there, I guess, are you using calcium nitrate? What's your source? Exactly. And then looking at also, what is the ratio of that nitrogen to your phosphorus and potassium? You know, earlier on, when we're looking at a bed cycle, we want to nitrogen to one ratio, FOSS.

[00:14:25] Seth: Two and two, one PK, basically. Ratio, and then we're going to later [00:14:30] bloom, you flipped that ratio. Now different PBMs are going to be effective at D. Yeah, different PPM ranges. Basically our house strong. Are we putting in. Typically you can have kind of a wide range of that. It's just going to affect the C level that you're seeing. So as far as PPMS go are typically running around.

[00:14:48] Seth: You know, 3.0. Which is 1500 PPM on PPM 500 scale, which is most commonly used. So, you know, a lot of times we're looking at running, you know, maybe five to 600 PPM nitrogen. Now, like I [00:15:00] said, if you're using calcium nitrate, you've got to look at, okay, we're not just putting in 600 milligrams per liter.

[00:15:07] Seth: Of calcium nitrate is not 600 PPM of counseling. It's 600 BPM nitrogen. Excuse me. We've got a calcium calculation we've got to do in there. So. I would basically stick to a general outline and up and down. Your overall ratio rather than switching your nitrogen PPM too much. And if you're really looking at how to do it, I mean, you can go copy a bunch of different feed formulas out [00:15:30] there.

[00:15:30] Seth: And feed charts that will tell you the same thing.

[00:15:35] Mandy: Awesome. Thank you so much for that. Tyler wrote in. Should I try to catch runoff and measure during the feed or poor. R O through after irrigation runoff. How high should I let runoff ISI rise during shin and beg before thinking, I need to push more runoff. Any advice?

[00:15:53] Seth: I mean, that's going to be tough.

[00:15:55] Seth: My best advice would be to go get yourself a substrate sensor, so you can actually see what's going on [00:16:00] in the root zone. And part of the reason for that as we're talking about runoff we've got to look at like, okay, do you have any channeling going on? Because if we've got channeling, our runoff is going to be a lot more reflective of the FIDI seat.

[00:16:12] Seth: Than it is going to be anything that's actually going on in, because that water didn't have time to modularize with. The nutrient solution in the block. Therefore, it's not going to pull any of the ions in the block out and tell us any change and what we're looking for. Looking at runoff ISI. Typically we don't want to see a draft higher than four or [00:16:30] five, but that's very dependent on what you're actually running in your root zone.

[00:16:33] Seth: And a lot of times those don't directly correspond. You're going to be a lot better taking the better off, taking the accurate measurement than trying to deduce how much your plan is. Feeding. For runoff measurements, the big thing we're looking for is a. Stacking above. We'd like to see a little bit higher runoff in the a higher UC in the runoff than the feed.

[00:16:52] Seth: And then we also want to see that PAs roughly stable to maybe slightly lowering a little bit. We don't want to see a drift up too far down. My biggest [00:17:00] advice is if you're at this point in the game, Go invest in a soul as it's going to keep you from chasing your tail so much. I mean, I spent years trying to analyze that and when I go back and look at my daily data, it's like, okay, this is spread out among a bunch of plants. Some have channeling some don't, some are getting run off every day. Some are getting run off every three to four days.

[00:17:20] Seth: So trying to get an accurate evaluation of that runoff is really tough. And it's better to rely on better data collection methods, rather than just stick [00:17:30] with that. And you can get decent results, but basically part of what allows growers today to run higher EDC is using substrate sensors because we can directly see what's going on.

[00:17:39] Seth: You know, and that's part of it too. Like if you go to take a bulky C measurement using As water, our water. That's not going to be quite as relatable is using a charge solution to pull a run off a sample. And then on the other side of that, if you were to run, you know, a bulky see extraction, so deionized or.

[00:17:58] Seth: Oh water. The way [00:18:00] we do that in lab is to go take a sample of that soil or that media take it into the lab, do the rents, and then do the measurement. Now, if we do that kind of technique where you either pulling media out of an already small pot. Or we're rinsing a bunch of BC that we spend all this time putting into the pot.

[00:18:18] Seth: Out of it. So it's a, it's kind of a risky move, trying to sample runoff too much. And especially with our water in application. If you, like I said, if you have a lab [00:18:30] facility and that's what you're looking at. That's an awesome way to analyze it. I'd love to be able to do that, but then at the end of the day,

[00:18:36] Seth: How many pots do you have to take a sample from every day to do this wash out? And where can you sample from the pot? Is the other side of that is if we're looking at soil sampling, we'd be using cores. That's also really not good for your one to two gallon cocoa pot to just take a one inch core out of somewhere in the pot, all the way from the top to the bottom.

[00:18:55] Seth: Awesome. Thanks for

[00:18:55] Mandy: that said. And thanks for everyone for sending in your questions. We're going to keep going down the list. [00:19:00] Caesar wants to know. How often should I feed nutrients in Coco? I see many growers who only feed twice per week and the other days only straight water.

[00:19:10] Seth: So I mean, essentially what you're doing there is typically running a pretty low ECE strategy.

[00:19:15] Seth: Which is not necessarily the worst thing ever. You're just not, as you're not taking advantage of that osmotic pressure. And controlling stretch. Now, when we're talking about cocoa, it does have some cat ion exchange capacity, meaning it can hold on to some nutrients, a little bit compared to [00:19:30] rockwool.

[00:19:31] Seth: Not very much. But another thing you can look at too is saying, okay, if I fed a 3.01 day, And I had the ability to really limit my runoff. You know, basically if I'm not pushing any of that salt out of the bottom, there's only one place that can go into the plant. Right. So if I've charged that up, I can keep getting it wet and maintain a level of salinity in there, but basically you're loading it up and depleting it over and over.

[00:19:58] Seth: And typically that means that you're staying at a [00:20:00] low EDC and riding on just, you know, not necessarily the ragged edge of deficiency, but again, we're not pushing it quite as hard as you could be. The other way and where that comes in though, is it. You know, Traditionally go back to the liquid nutrient discussion, but.

[00:20:16] Seth: It ties in. If you're buying liquid nutrients, you probably aren't buying as much fertilizer, which means you probably aren't investing as much into sensing technology. Which means running a Hi-C is much riskier for your operation.

[00:20:29] Seth: You [00:20:30] know, Hi, AEC has its benefits, but it also is a lot tougher to manage pH and can definitely lead you down some confusing roads when you're trying to diagnose plant health and you've got high. Higher low pH. And then, you know, other issues associated with a potentially very tall ISI range throughout your dryback.

[00:20:50] Seth: And if you don't have eyes on that, It can be very difficult. It might be like, is it a pH problem? Oh, I think so, but I don't know what's going on in the substrate. So I don't know if it's pH or did my [00:21:00] ECE massively fluctuate today. So that's really getting that baseline down is pretty important when we're trying to determine things like that.

[00:21:09] Mandy: That's super important to keep in mind. Awesome. Thanks for that. Indie bud wrote in. I got so much knowledge from you guys and I can't. Thank you enough. Oh, that's super nice. I'm going in on my first run. I'm in Coco. I have two rooms and one sensor will. I ruin my grow. If I just water two times a day till full saturation,[00:21:30] what kind of advice can we give in that situation? So,

[00:21:32] Seth: Would you mind repeating that the media, that he's in. Yes. Coco. Okay. Okay. So it depends on what size pot you're looking at, you know? If we're trying to run generative and a. Properly proportion, plant to pot size. We can hit that 22 hour dryback. Bringing you to saturation twice a day is, I mean, depending on how many shots you use is not necessarily

[00:21:53] Seth: Articularly vegetative. Although definitely is a little bit when we're opening up that irrigation window. However, if you're in [00:22:00] a smaller pot, like let's say we're in a one gallon Coco pot, we're shooting for a four to five foot tall plan. And paired to a two gallon pot with the same plant size. We're definitely going to be, you know, a little more sensitive to drying back too far, just because we don't have as big of a reservoir for that plant all from.

[00:22:16] Seth: And in that case, that would be where you're going. Hey, I know I'm going to overdrive if I'd go for that 22 hour dryback. So at the end of the day, I need to put on a shot to correct. And how much I might over dry. Well, if the media you're using, like, let's say you have a [00:22:30] cocoa that's hitting 44 or 45% field capacity and you're hitting a 25% dry bag.

[00:22:36] Seth: Early, let's say an 18% dry back by the end of the day. All right. You're already getting down fairly low and you know, you're going to overdrive by another 10% overnight. You're safe as bad might be bringing it back up close to field capacity, the danger there is pushing extra runoff for no reason. So that's something to think about if you're approaching field capacity later in the day.

[00:22:57] Seth: Are you going to rinse out extra ISI? [00:23:00] And do you need that second full drench to really ride it out until the morning? If you're not going to overdrive your plants? It's probably not necessary to bring it back up that far. And, you know, Maybe you could be a little more efficient with water, use that way. And also, like I said, possibly monitor your runoff better and maybe allow to get a little more control over how your ECE stacking inside the pot.

[00:23:23] Mandy: Awesome. Thank you for that. I'm going to keep going down our list. Nasta. Coast wrote in. Do you think running [00:23:30] my room at 1800 PPM CO2 is a waste of money. And what week would you start to taper CO2 in flower? Thank you for all the InfoSec.

[00:23:39] Seth: I mean, so CO2 is always going to be directly proportional to how much light's going into the room. Right. And then also our ability to give it.

[00:23:46] Seth: Enough nutrients to support that level of growth. So if we're looking at 1800 PPM of CO2, Are you running 1500? PPFD. And at that point, I mean, that's pretty high. There's not a lot of people pushing it quite that far.[00:24:00] But that would be the case. Like that's when you would need that much CO2. And, you know, our basic rule here is about

[00:24:06] Seth: PPFD plus two 50. And PPN. So anytime you're actually thinking about decreasing your CO2 amount or increasing it, it's always directly proportional to your lights. So if you're looking at, Hey, I'm actually dimming my lights in the last week of flower. You can pull your CO2 pack. Quite proportionally, you know, and yeah, basically at the end of the day, if you say, have, you know, what's really common about a thousand [00:24:30] PPFD at canopy.

[00:24:31] Seth: 1800 would be just pretty much venting money out into your atmosphere for sure. The cost is probably not something that's going to kill you. But it's definitely one of those spots where you could tighten up. And find a little cost efficiency inside the system you're running.

[00:24:47] Mandy: All about controlling those input cross.

[00:24:49] Mandy: Awesome. Thank you for that. Seth. Tyler has another question. We use two gallon Coco key and perlite from start to finish with two week vege only [00:25:00] need to irrigate during vege three-ish times. Is it worth it? To use four by four cubes per vege and put those into one. One and a quarter gallon Coco for flour.

[00:25:11] Mandy: I think so.

[00:25:12] Seth: Yeah. That's actually not a big, not a bad plan. I find with the four inch pots, you know, even if I was just transplanting those straight into a bigger pot. I'm getting a lot easier badge in terms of effort on my part, because it's much more difficult to over-water that small pot. And it allows me to get a much faster route in when the [00:25:30] routes only I have to call. And I as a four by four space.

[00:25:33] Seth: And basically instead of watering two or three times in a two week vege, I can start watering. Pretty much a day or two, right after transplant, especially with the hyper, like concentration in there. And what that does is allow me to have just a little bit more uniform crop when I'm not waiting for them to push routes nearly as long. And then also, you know, one thing we see is that transplant has.

[00:25:54] Seth: Pretty good hormonal reaction to the plant. We gone go from that four by four and put it into a bigger media. [00:26:00] Exactly root growth has to be driven by oxen production. So when our roots are growing, that's also putting the plan to a hormonal state that once those roots can support it, the upper part of the plant is also going to grow up much faster. So.

[00:26:11] Seth: That's kind of part of why you see, you know, the all, not all the rage, but this bigger movement towards stacked media. And if personally, if I were going into a one and a quarter gallon cocoa pot, I would be looking for like a 0.3 gallon. Okay. That I can just set on top of there. And that's got two benefits. One those roots go down out of [00:26:30] there faster and more aggressively.

[00:26:32] Seth: And it allows you to pulse those roots by putting your irrigation in that top spot, that top pot pulsing it down through those roots are going to follow that water movement. And you're also keeping that plant up there. Healthy. And then it's also less labor. It's easier.

[00:26:47] Seth: I think he can make an expensive Coco key work through flour, and they're a great medium choice and that's absolutely true as well. You know, if you're at a two gallon. It's a good point, Mikey. You're going to a one, one and a quarter. You might [00:27:00] notice your bedtime house was a lot easier, even with the one in a quarter compared to the two gal.

[00:27:04] Seth: So it might be worth giving that a shot before going too crazy with mixing it up.

[00:27:11] Mandy: Awesome. Great question. And Mikey, awesome feedback. If you make. If you can make a six by six cocoa cube worked through flour. They're a great medium choice. Great. Love the knowledge sharing on the show. I'm going to keep going down our list. Let's see. Who's next. Cesar has a question. With a good nutrient base. Our [00:27:30] supplements really necessary. I see many growers who put too many bottles into their reservoirs.

[00:27:36] Seth: I mean, yeah. Yes, you nailed it. You know, if you've got a proper nutrient base, you won't need to be supplementing things. There are certain things that don't mix well. And solution than others. Like, you know, there's a reason Cal-Mag is usually a separate liquid it's because it doesn't make a good salt mixture.

[00:27:52] Seth: With other components same with most Silicon supplements. So, you know, The answer's. Yes. I [00:28:00] mean, you can put in some other supplements that for growing purely in a hydroponic system, though. Basically most rockwool. Our goal is actually, you know, not to have the most biological activity in the root zone. We're trying to skip all that and give the plant direct nutrients.

[00:28:13] Seth: And Going to a high level of additives. There's a certain point where we've gone past. Our basic plan, essential elements, what we call nutrients. And that's where we're diving into some of the world of like, Oh, some of your like molasses based products, aminos and other things. And some of those products that have a lot [00:28:30] more advocacy and really actual living soil type applications, because what you're doing is feeding a lot of those microbes in there.

[00:28:37] Seth: You know, if we're putting sugar and carbohydrates into the soil. Plant camp uptake, carbohydrates through its roots, but if you have a bacterial community down there, that's going to produce some of the different things that the plant needs. Or be able to metabolize phosphate and things like that. That's what we need to feed most of our commercial situations like that. We're not dealing with trying to put too many additives in because it makes it a.

[00:28:59] Seth: Much [00:29:00] more difficult to maintain your irrigation system and yeah, you nailed it. We're trying to provide in this solution that is ideally specialized, mostly for plants and not a bunch of other things that we don't want to grow in the room. We're trying to give it everything we need. Or everything it needs. And the longer cannabis specialized fertilizer companies exist, the better they're getting at really targeting.

[00:29:22] Seth: What exactly is needed and there, and that's another cool thing, you know? In terms of plant research and fertilizer research over the years, everything's [00:29:30] experimental, right? So it takes years of research to prove that like, let's say molybdenum is a plant essential element or nickel. There's a field of things. We can go down that line, but cannabis is allowing us to do it at a little bit more accelerated pace because cannabis growers typically pay a little more for their fertilizer.

[00:29:47] Seth: And we're going, you know, we're approaching this from the high input side and trying to make it. A little bit cheaper. Rather than approaching it from. What is the cheapest possible way we can get [00:30:00] any kind of crop out rather than, you know, there's a level of quality in cannabis. That's really pushing the suppliers.

[00:30:06] Seth: Fertilizer and you know, everything in the industry to constantly up their game and try to stay on the cutting edge of science. You know, as compared to a lot of the bigger ag world where. I mean, we've got fried into products, you know, to. Two four D if you're talking to anyone that sprays fields that's been around a long time, it's still in use in a lot of places. Cannabis things progressed faster, so it's getting better and better all the time. [00:30:30] Trying to get less bottles to put in your tank. That's for sure.

[00:30:34] Seth: It's such

[00:30:35] Mandy: a great industry to be a part of too. It's always changing. That's a great question. And thank you for that advice. Then Tyler has a question. What generally causes Rivage Fox tails and weeks five tonight and

[00:30:46] Seth: flower.

[00:30:48] Seth: A couple of things, you know, If you're seeing it just on the higher, the Cola's on your plans to top next, a lot of times heat. Just go get a thermometer out there. And that if that nugs 85, 86 [00:31:00] 90 degrees at the surface level. That's probably pushing a lot of that foxtail formation, especially with certain genetics that are more susceptible to it than others.

[00:31:08] Seth: We can also look at, you know, repeated bulking stimulation in the plant. So basically at some plants, genetically will respond to repeated bulking. By continuing to vet, especially in combination with running a higher nitrogen concentration later in flour. Yeah. So this before I'll say it again. There's a good reason that a lot of older feeding schedules.

[00:31:28] Seth: Would really back [00:31:30] off on nitrogen after like week four or five and even, you know, read three, four sometimes. Just because in certain plants that calcium nitrate will have an oxygen, like effect that'll cause the plant to continue to stretch. So that's part of that box tailing is when you're pushing vegetative growth with nitrate and repeated bulking signals, that's telling the cells in that plant to stretch out.

[00:31:52] Seth: And also implants that are genetically predisposed to start forming those Foxtails. So a good place to start is to see, Hey, am I seeing, you know, I [00:32:00] always check temperature first because that to me has been the One of the biggest reasons I've seen it typically it's like, Hey, why is it just in this corner of the room? Like, okay, that's where the D is blowing down or we just can't get it cool over there.

[00:32:13] Seth: All right. That's a good sign if it's on every single, but all over the plan. And a lot of times you can see, I wish I had some pictures here to show. It does Foxtails are, you know, pretty mashed down together and you're not seeing a whole lot of pistols coming out. You're just seeing mash.

[00:32:27] Seth: Basically Brack stacking up. [00:32:30] That usually leans a little bit towards that late nitrogen condition. Whereas the classic loose Fox tail with just a little stem and a couple Bracks on each side, shooting up. That's a lot more of that heat leaning, genetic response.

[00:32:45] Mandy: Yeah. Ox feeling. It's a crazy topic to talk about, but write that down bars. Awesome. We're getting the questions over on YouTube. Tom wants to know, and this has a couple of. Couple of parts to it. So hang in [00:33:00] there with Nissa. Tom wants to know hello guys. Thanks for all the great info.

[00:33:04] Mandy: I'm currently in Vedge with 18 inch tall plants and Delta 6.5 S. I'm looking to transplant into 2.5 gallon cocoa bags. What would you say would be a good initial irrigation strategy for the route in process? I was thinking about continuing with the current irrigations I'm doing until I see a 15% dryback in the cocoa bag.

[00:33:25] Mandy: Then switching to sizing the shots for the cocoa rather than the 6.5.[00:33:30] I am just a little worried. The cocoa might wit too much moisture from the 6.5. The Coco will I will be using only has 40% fill capacity. Any advice for him?

[00:33:41] Seth: Yeah. I mean, the first thing to start out with, make sure gravity is your friend.

[00:33:45] Seth: Don't actually bury that cube too deep in there. You know, if you have a four by four by 2.5, don't bury that instead it right on top. And then put your emitters right into that. Rockwool cube. Especially for that first week or two. Because what you can do is basically you're going to push water through [00:34:00] that down into your cocoa and yeah, you nailed it. You're going to do deep, smallest micro irrigations. You know, one purse basically, though, what I would suggest is 1% of that cocoa volume.

[00:34:10] Seth: Once a day until you start to see that dry bag fall, once you passed about 6%, you might hit it with too. As long as you're seeing that line continue to fall. And then yeah, 15 to 20% total dry back. And you can start applying Who your, you know, your two gallon Coco.

[00:34:27] Mandy: Awesome. We love that. I keep the questions coming. And [00:34:30] then Mikey just gave a comment, give your roots space to grow down and allow the cube to vent moisture out of the top of the cocoa. Good advice.

[00:34:37] Seth: Yeah, I really want to stress. I've talked to quite a few people and that's been their biggest hiccup with stacking media is resisting the urge to bury that in there.

[00:34:46] Seth: You know, your rockwool cubes have the little airation Stripe or aeration gaps on the bottom. The little ridges. The flatter your coconut can be. And if you can still get oxygen into there, then you're, that's the best you're going to do as far as preventing that week. [00:35:00]

[00:35:00] Seth: Awesome.

[00:35:01] Mandy: Thanks everyone. I believe that's it for the questions on YouTube. Thanks you guys. For all of those. Keep them coming, but until then, I'm going to pass it back to you. Kaisha. Some thank

[00:35:10] Kaisha: you, Mandy. Yeah, just a reminder. You know, the way this works. If you want a question, you want to get your question answered by the expert, the best way to do, to be live on the show. So 11, all that activity on YouTube. Do you have anything you want to ask? We got a little timeline on the show.

[00:35:23] Kaisha: I'm going to go to this YouTube question here. We got a couple of weeks ago, but didn't get to, they wrote in, I want to prevent, [00:35:30] but by mold, due to calcium deficiencies. Was wondering what ISI of calcium nitrate through run the last week of flower running Coco. What do you think, sir?

[00:35:40] Seth: I mean, very low.

[00:35:42] Seth: That's where looking at calcium silicate Cal-Mag anything other than calcium nitrate. But you're right on. It's not just calcium deficiency. It's several deficiencies that are linked to calcium deficiency. That's causing, you know, death in the plant late in flower. Typically, I mean, I'll still run a 2.5 to 3.0 [00:36:00] all the way through the end. The biggest thing, and that's why we see companies, you know, with Athena.

[00:36:05] Seth: Not so much recently. And we're for awhile, they've actually had their fade product out to help growers deal with that and getting, you know, the correct calcium EDC in there without having to add calcium Lightroom. So I made. The best answer I have is trying to find a way to pull that calcium nitrate severely bad or out and supplement calcium.

[00:36:24] Seth: With a different product.

[00:36:28] Kaisha: All right, friend. Yeah. Good [00:36:30] luck out there. Thank you for that too upset. I'm going to send it back to Mandy. I think we have a poll on YouTube. We've got some results.

[00:36:38] Mandy: Oh, my gosh. Janice. I'm trying to make sure that I had the most recent poll. Answers in. All right. The

[00:36:44] Kaisha: latest breaking

[00:36:45] Mandy: news, right. Yes, this is late breaking. Sorry, you guys, people are just passing me news left and right here. So we wanted to know which topic keeps you up at night.

[00:36:53] Mandy: Has management, genetics compliance or extracts. So what are you guys thinking about when it comes to your grows?[00:37:00] And we had 40% came in at pest management. So you guys are thinking about that. Okay. So you guys are dealing with bugs. You guys are trying to get ahead of them. You guys are trying to deal with that.

[00:37:08] Mandy: Are there with you genetics? It came in at 30% love that. We're always thinking about genetics over here to compliance came in at 30% also. Okay. We're all dealing with that. Got to follow the rules and then extract 0%. But I think that it's just because we had a lot of big topics on this one.

[00:37:24] Mandy: So thank you all for voting and we love posing holes. So we'll have more for you guys next time. Back to you, [00:37:30] Kaisha, for more

[00:37:30] Kaisha: questions. Awesome. Thank you, Mandy. Yet pest management. Just the topic that. The gift that keeps on giving. Right. Everybody. All right. Moving on to another question that was submitted a little earlier from Dr. J three or three.

[00:37:44] Kaisha: They wrote into you recommend running off every day. I have not been getting enough. And it starting to burn some leaves week 6.5. What do you think? So.

[00:37:55] Seth: Yeah, I mean, that, that goes right back to the origins of the whole drained away system that we're running here with [00:38:00] drip irrigation on a soil as media. Part of the, part of what we're doing is really inputting, you know, the most complete nutrient solution that we can.

[00:38:07] Seth: And once we put that into the media, the plan actually wants, especially once assaults. Dissociate and dissolve completely in the water. You know, like when we put calcium nitrate and for instance that's assessing, that's turning to calcium and nitrate is two separate ions in solution. And the plan has the ability to pull, you know, calcium ninth grade. They can put both but other other ions you find in there that are positively charged the plant. Generally [00:38:30] isn't pulling them in. So part of what drained a waste is we're pushing out and not for those positively charged ions.

[00:38:35] Seth: And resetting that pH balance every day, resetting that nutrient balance. So we do want to see, ideally run out a little bit or run off every single day in a good way to really kind of monitor that if you're not getting enough and you are seeing some plant health issues. Is do want it around, off collect that and see what your pH is doing.

[00:38:56] Seth: You know, And one thing too about this, when you do go to do that high [00:39:00] grace, you know, we talk a lot about channeling and stuff, but the best. Run-off reading you're going to get is if you can manage to hydrate that media slowly and make sure you're not getting any channeling or premature runoff after let's, you know, if you need.

[00:39:12] Seth: For four year to recover your dry back, but you're getting run off after your second. That's not going to be quite as representative as if you can slow that down a little bit and manage to own, they get run off at field capacity because that's a given most of your irrigation water time into homogenize with that route. [00:39:30]

[00:39:30] Seth: Route. Area, nutrient solution. Sorry. That was hard.

[00:39:36] Seth: You know, we want to really see what's going on in there. And once you do start seeing signs of that burning, that's typically what it is we've got a pH drift because we haven't been resetting that ionic equation every single day. So. I got to sit down here before typically I only like to run about three days with no runoff, if possible.

[00:39:53] Seth: Sometimes, you know, it might get pushed to four or five if I'm trying to really get that you see yet, but. I know that sense of my [00:40:00] pH if the plants healthy should always be drifting down a little bit, compared to my input. My input pH. That tells me the plants eating that tells me I really want to be replacing that nutrient solution as much as possible.

[00:40:13] Kaisha: Fantastic. Thank you for those hot tips. All right. Back to you, Mandy. What's going

[00:40:17] Mandy: On YouTube. Oh, it's popping over there. Y'all know it. Brockett, bud farms wants to know. How should I water my Fino hunt with all plants on the same line. Thanks for all the knowledge you guys are amazing. [00:40:30]

[00:40:31] Seth: I well, I mean, Step one, take it for what it is. It's a Fino. So try to have somewhat of a rigid timeline where you say, Hey, when we're hunting, Finos we just follow this standard procedure. And then, you know, realize that you do have all these different genetics on one system. And then when you are doing Fino, Hans, there's a few things to consider too.

[00:40:52] Seth: Personally. My favorite way is to sprout seeds, take some cuttings and then grow those cuttings. And not typically female hot, the actual seed [00:41:00] sprouts too hard themselves, just because. I'm not going to be growing seeds after this. So, that's not going to be representative a lot of times we see opposite bud formation compared to alternate bud formation and a few other differences between seed, ground plants and.

[00:41:13] Seth: Flown grown plants. So that's a good spot to start. That's also going to keep, you know, a little bit more management on your media size. Like if I'm starting from seeds you know, I've got a taproot and play. Typically want a little bit different pot style and size than if I'm going from clone.

[00:41:28] Seth: The other thing too, [00:41:30] is once you've got that standard recipe, you're probably going to be around me is not the highest DC. Cause you kind of got to make everyone happy and try not to kill any of uncertainty, probably pushing a fair bit of runoff. And then from there evaluating, okay, what are we actually looking for here? Are we looking just for quality? I mean, you've got to have a pretty good way to select for these plants.

[00:41:51] Seth: In a way that's going to work in your system. So if you've got a female hon, a good place to start as like, Hey, we need to figure out how to throw away 90% so that we can blow. [00:42:00] Some up at least a one valve, and then we can properly evaluate how well it's going to perform for us because. I mean personally and phenol, Hans, I found some plants that were, seemed awful.

[00:42:12] Seth: And when I went and grew them on my own outside of the facility. I got great results off of those cats, but. Those particular, you know, Finos that we were hunting just didn't really, they had a different morphology, there are different sides and everything on the bench. We didn't get a good expression during that first run. And I think that's something you just gotta be [00:42:30] aware of and try to sometimes limit your Fino hunt to only so many different Finos at a time as well.

[00:42:35] Seth: Make it manageable. So you say, Hey, I really liked. You know the nose on this one. Like the bud structure didn't put out as much as I wanted, like, okay. Let's keep that one and give it a second chance and not just look at yield off of that initial female hunt. It's a time-consuming process. And it's that I will admit it's hard for girls to keep up just because of the menu is always changing out there. Right. When everyone's trying to do it, it's constant competition. It can be [00:43:00] stressful, but.

[00:43:01] Seth: It's just part of the game.

[00:43:03] Mandy: She was part of the game. Mike, he had a comment here to run close to the SOP. Those that don't make it won't fit your standard program and aren't worth keeping around unless it's a unique and fun strain. Yep. Yep. I agree. Awesome. Great questions over there on YouTube. I think it's, I think that's it for now. So I'll pass it back to you, Kaisha.

[00:43:21] Mandy: Thanks

[00:43:21] Kaisha: Mandy. I love talking about Fino hunts. I'm like Pavlov's dog. I immediately started thinking about. What I get to enjoy me. [00:43:30] Awesome. All right. We're back. We branded at the hour. Folks, if you have any live questions, now's the time to ask. We got a comment on episode 64 of YouTube. Obviously I was on YouTube and I wanted to run this one by, you said you were also in that.

[00:43:43] Kaisha: Basically you were talking about how dry back is the sum of a lot of different factors, VPD heat. Rightsource. And what is that need? And The immediate two millimeters around the leaf surface. So Peter wanted to get a little bit more information. He wanted to understand that a little more, a little bit more.

[00:43:58] Kaisha: That immediate two [00:44:00] millimeter around the leaf surface, please enlighten me. Okay.

[00:44:03] Seth: So, you know what's affecting the plan in terms of transpiration at when we're talking about that leaf surface, like just that immediate Zone right around the leaf, basically. That's the environment, the plant lives in, right? If this is a leaf surface,

[00:44:15] Seth: And I put my hand over here closer to the grow light. That temperature is not reflective of. What's being felt right here. Right. So what we want to do is shrink that area down to what's really going on in the leaf surface. Cause that's where esta Mata exist and that's where everything's [00:44:30] responding to. So.

[00:44:31] Seth: You know, if we've got, for instance, a great air movement above the lights. And great control up there, but then we have poor air movement and the canopy. Now we don't have a very, you know, Homogenous, can it be, we have different rates of transpiration going on. So what we really want to focus on that area around there, the only problem with that is right.

[00:44:49] Seth: It's a. I mean, you could use not for this purpose, but as an example, I wish I had an, a leaf parameter, which kind of looks like a crazy science clothes pin that he clip on a leaf, but [00:45:00] there's not a good way to just attach a sensor to your leaf and get that leaf surface temp and the conditions around it.

[00:45:04] Seth: So what we do is we use, you know, things like relative humidity, but mainly VPD. And then we do a leaf temperature calculation, then factor out the differential, you know, to what it would be given the condition, the temperature, right on the leaf compared to what we're seeing anywhere else in the room.

[00:45:20] Seth: And where that comes together with dry bag is if you. Use VPD. You start to calculate transpiration rates. You're looking at, okay. This plant takes up so much [00:45:30] water over so much time. And that really is what determines what our dryback is going to be. So if I have a one gallon pot, for instance, versus a two gallon of the same media,

[00:45:40] Seth: And I have the same size plant and each one is going to dryback so many milliliters of water. It's going to consume that amount. That dryback percentage is going to be proportional to the plant, the media. Right? So if each plant consumes 600 milliliters of water in a day, or let's say, you know, more like 12 or 1500.

[00:45:57] Seth: That percentages can be different compared to the [00:46:00] media size. That's why, like when we're talking about dry back percentages, there is a fair baseline. We want to see that indicates you have a well proportioned plant and media size and water concentration. But. You know, again, that's the sum of a lot of factors. So if the leaf temperature warmer, we see increased transpiration because the BPD is higher in the area immediately surrounding this demand.

[00:46:24] Seth: It's at least surface stem. It gets too high. Then the VPD right around the lead gets too high, [00:46:30] even though, you know, that would be the case. Let's say where we have an 82 degree. Ambient temp hid room, but we have some hotspots in there under the lights where, Hey, that leaves surface temp is actually like 86 degrees. All right. Those particular leads are hitting that point where they're actually getting, starting to shut their stemmata.

[00:46:48] Seth: And slowed down transpiration. So that's why at least surface temperature is so important because it can vary, depend on depending on different environmental factors in the room and just having, you know, a thermometer [00:47:00] hanging. Or a sensor that tells you VPD there. Isn't necessarily going to guarantee that you have great leaf surface conditions and that you're going to get the desired output compared to what your environmental conditions are.

[00:47:14] Kaisha: Fantastic. Thank you for that overview. It's kind of fun. Jessica question from a few episodes ago, I love that. Oh, yeah.

[00:47:22] Seth: Well, I get that one a lot too.

[00:47:25] Seth: Yeah, and I think it's because so much of the conversation around crop steering in general, just revolves around the dry [00:47:30] bag. You know, it's become another quantified number where mine is bigger than yours. Basically right. Man, you're only pushing 15% drybacks. We'll look at this, I'm pushing 25 and here's some pictures of some frosty, bud, you know?

[00:47:43] Seth: There's a hype thing on it, but it is, it's all very relative. And I think people really need to remember that when. You're comparing your particular data or results with another grower. Unless you've been to their facility. And I can tell you I've been to a lot of these. They vary [00:48:00] so wildly with so many different little factors going on than it is really. You really can't compare apples to apples based on just to dryback percentage, even in the same media with the same nutrients.

[00:48:12] Seth: I mean, you better have everything the same down, you know, right down to at T to really compare that.

[00:48:18] Kaisha: That's right. Stay away from those comparisons growers. Yeah, laughing. Okay. We have a few more live questions on YouTube. Let's get to those over to humanity.

[00:48:26] Mandy: Awesome. But whose drawback is bigger?

[00:48:28] Mandy: I don't know. Sorry. How'd [00:48:30] you all right, let's get to these questions. Y'all. My dad, 86 wants to know. Just adding a sweetener to a hydro system, really improve

[00:48:39] Seth: flavor and smell.

[00:48:42] Seth: I mean, it depends on what that sweetener product's supposed to be. I can't see it now. And when we're talking about like bud sweetening products, we've got, you know, general micro boosters, PK boosters. And in those cases. Yeah. If you're already doctoring up a nutrient solution, that's not necessarily deficient, but could use more of that to push the plant.[00:49:00]

[00:49:00] Seth: The thing to look out for is some of these sweetener products, like I said, are a little more marketed towards people growing in soil. And, you know, using probiotics generally. So you're feeding microbes with some of those sweeteners. If they have carbohydrates, some that I've seen marketed are just simply bloom enhancements. And what they allow you to do is run a fairly conservative.

[00:49:20] Seth: Fertilizer solution. And then basically add those in to up your PK ratio and micro ratio and push that. That growth and the plan a little bit. [00:49:30] So do I think they can work some of them? Yes. Depending on what nutrient line you're running. Is it the end all be all in that nutrient line? Probably not. That's like a finishing touch on having everything else dialed. So you're actually getting, you know, a healthy plant and at week eight or nine and not one that is already dying from, you know,

[00:49:51] Seth: And I was modic shock or something else like that.

[00:49:56] Mandy: Awesome. Thanks Seth. Caesar has a question. Do I [00:50:00] really need to fade or as long as I follow the Athena feed chart, will I be

[00:50:04] Seth: fine? It highly depends on the strain. And that's the way to put it. Basically, you know, we do a lot of talking on this about, on this show about like late nitrate availability for plants. Some plants will respond to that late nitrate availability.

[00:50:19] Seth: Ablate nitrate availability in the root zone by taking it up and expressing more vegetative growth. I E. New Bracks, white pistols, et cetera. Others are [00:50:30] less sensitive to uptaking that. And also, you know, there's another factor that comes in here. That's levels of determinism in the plants. So when we look at plants that flower a much shorter period of time,

[00:50:41] Seth: Typically, one thing we see is that, you know, those are a lot more close and closer to a true determinant plant growth and can auto flower where. And these plants, once we flip them to 12, 12, they're marching and they're going to stop when they want to stop. Other plants, you know, we go back to like some of the more

[00:50:57] Seth: Oh, geez. Hayes is traditionally just get stretchy [00:51:00] stuff. When you stimulate that plant to keep growing. It will just because in the environment that those genetics involved, it evolved and they may not have a season that absolutely kills the plant out at a certain time. So their natural selection or human selection, hasn't lended to the plant being that determinant. So basically, like I said, some strains, you're going to be fine.

[00:51:23] Seth: Totally fine. Running that late nitrate all the way through. Other ones you're going to see late white pistols. Sometimes bud stretching [00:51:30] apart looser, bud formation. And a general resistance in the plant to wanting to mature the way that we expect it to.

[00:51:40] Seth: Awesome. Thank

[00:51:41] Mandy: you though, for that set. I think we have time to get to one or two more questions. And Chad has a question. Running Rockville media. Do you keep a strict blind on how far to try back? I E do you not go below 30? If my volume metric water content is only getting to 45%. How do I [00:52:00] get a big dry back? If I don't go below 30%?

[00:52:03] Seth: Well, I mean, this really goes back to one of the things that scares a lot of girls off of Rockwall initially. And my hard line is 40%, especially if I have sensors because. I know that I don't have a sensor for every plant or every slab. And if I know for a fact, if I go down below 35, I'm going to start developing some hydrophobic pockets that will not allow the media to reach the field capacity. And previously had.

[00:52:28] Seth: So [00:52:30] 40% is the hard line. And then really, yeah the reason a lot of girls we got get scared off a rockwool initially is if you do too far of a dry bag, you know, Just after rooting in just after transplanting or at any point during generative, when those plants are growing and taking up more and more water.

[00:52:45] Seth: Now you have that dwindling field capacity and you're basically shrinking your pot. You're shrinking its ability to hold water and make it available for the plan. So you're effectively limiting how big your plant can get in that pot. And when you do that, you're going to [00:53:00] suffer. You're going to see reduced yields at the end.

[00:53:05] Mandy: There we go. Awesome. Thank you for that said, I believe that's all the questions for YouTube for now. So I'll pass back to you, Kaisha.

[00:53:13] Kaisha: Awesome. Andy, thank you so much. All right, we got a good one here from chest. He wrote in and what would be the highest BPD or preferred to BPD from mid flower to ripening?

[00:53:24] Kaisha: If, you know, you will not have mold issues.

[00:53:28] Seth: The highest. So. [00:53:30] If I'm. I mean, that's a, that's really competent statement. But. If

[00:53:36] Kaisha: you're yeah. And, you know, for a fact that you're not going to have any mold

[00:53:40] Seth: issues. Well, I mean, and there's, there are some people who are fortunate enough to live in a climate location and facility to where they're able to isolate that from their environment.

[00:53:49] Seth: Not everywhere has an apple tree by the front door, the air intake. So that's, that is possible. Typically though, just for general transpiration and plant health. We want to see usually [00:54:00] between a 1.2 to a 1.4 or five. For max transportation. As you know, approach bigger and bigger buds, typically you want to keep it a little drier in the room, just because, you know, if you get the inside of a bud wet, you know, add a little tiny fan, you can go put by each bud to dry it out. Right.

[00:54:17] Seth: So typically, yeah, it's still about 1.2 to 1.4 range. And especially, you know, when we're talking about late flower, one challenge, a lot of girls find is. Maintaining that same BPD overnight. You know, my, [00:54:30] my general rule of thumb and this just comes from years of growing in greenhouses is that if my VPD drops below a 1.0.

[00:54:36] Seth: The last two weeks of flower for almost any amount of time. I'm going to be looking for mold. I can very much expect to see it. So that's where, you know, We kind of talk to people in the past about like, Hey. If you can't maintain 43% our age at 65 degrees, if you do that and you still can only hit like 60% humidity.

[00:54:57] Seth: That is a pretty hard line where you're [00:55:00] quite potentially going to run into mold problems, especially if you have any condensation in the room or anything like that. So even if it's not in your environment, You can also run into other problems. And this is one thing I have seen where you do have, like, let's say one condensation grip in the room from an AC unit.

[00:55:17] Seth: Or a pipe or something on the ceiling. That drip can hit one bug. And another thing we've seen as a lot of cocoa comes in with some Aspirgillus into. And it eventually right. If you have that [00:55:30] available in the room, you get a bud to sopping wet. There's a good chance. You're going to get Aspirgillus to pop instead of detritus, which is, you know, not only can destroy that, but.

[00:55:38] Seth: Potentially failed the rest of the room. So. There's always some, they consider generally speaking. We want to keep those buds dry in the end and there really is. No. You know getting too hot and dry is probably going to sacrifice quality but as long as we can keep those tamps a little lower in the daytime you know 75 or so and maybe a little less Then [00:56:00] we're going to run it okay for that to have quality running again super high not a huge benefit less reporting mold Super low even if you could run up 0.9 for the last two weeks with no mold That would also be no growth or maturing benefit to that

[00:56:17] Kaisha: Fantastic thank you so much for that sense all right we're going to close at the hour with a very controversial poll results Oh, my gosh, Mandy

[00:56:26] Mandy: What's the news we got the news in hot off the press you guys The most important [00:56:30] question we asked you guys help us with our next meme theme Did you guys want chris barley, patrick swayze anchorman or matthew mcconaughey oh my matthew mcconaughey what was the tie between chris farley and patrick swayze yeah Thank you for. Everyone for chiming in for that one We're going to leave it at mystery which one we're going to pick though so you'll have to tune in, follow us on all the platforms awesome

[00:56:52] Kaisha: Hello everyone So good mandy is the meme queen so any inspiration is always appreciated for the best [00:57:00] part is that we don't know what we're going to see until we see it The magic we all see the magic all at the same time together All right, the last couple of minutes before we go i'm going to turn it to me Seth. I have two little cannabis ceilings in grow bags in my backyard they've been out there now for about two weeks I am watering them every day but they are noticing a little bit of yellowing and i'm worried that like maybe this is now the panic starts immediately am I watering them too much am i not watering them enough i don't have a [00:57:30] soul as i don't have a aroya i need to get it together But what do you think

[00:57:34] Seth: Well i'll send you some of those things but i think you need fertilizer That's probably Most of your potting soils don't come charged with very much of anything and they might come with a little bit of nitrogen starter And that's about it so even if you bought like fox farm or one of the traditional unesco companies you might buy it from you still typically in a pot want to start supplementing Okay

[00:57:57] Kaisha: Got to get my new chance in there all right i'm on it [00:58:00] Yes please send me a care package thank you so much okay Awesome i think that's everything right mandy anything else on you do

[00:58:08] Mandy: I believe that's all we have over on YouTube. thanks everyone for your questions and thanks for joining us today
