[00:00:00] Kaisha: All right. It's Thursday at 4:20 PM That means it's time for Office Hours. AROYA's weekly session for cultivators to hear from the experts and talk to each other about what they're seeing with their grows. My name's Kaisha and I am co moderating with my good friend Mandy. What's up Mandy?

[00:00:13] Mandy: Hey Kaisha, super excited to be here. We're here for episode 43. The crew's all here together again. Did you guys know that we're also going live over on YouTube right now. I'll be watching for your questions, so don't be afraid to send them on over and I'll get them to the team. Also be sure you're following us on Instagram and [00:00:30] TikTok if you aren't already. But I heard word around the virtual office that we got a lot of questions for Seth and Jason this week. So I'm gonna throw it back to you.

[00:00:37] Kaisha: Ka. Yeah. Thank you, Mandy. Yes, we have a lot of questions today, but you know our live attendees, you are the focal point. If you have any questions for us, be sure to drop 'em in the chat.

[00:00:46] Kaisha: Let's get your question answered by one of the experts. Seth. Jason, how's it going guys? Great. Good to see you.

[00:00:53] Seth: We're in our bright white room here. Sorry. Oh no. Squint que at the camera all day,

[00:00:58] Kaisha: meaning business in that [00:01:00] big, bright white room. All righty. You ready for our first question from Instagram?

[00:01:04] Jason: Get it going.

[00:01:05] Kaisha: All right. This one comes from Mark Ms. 90. First of all, he starts out with thanks to Seth and Jason for all the knowledge over the last 41 episodes. Not all heroes wear capes facts. All right, first question. They submitted two questions this week. They wanted to get your thoughts on the strict T Y A M microbial limit.

[00:01:25] Kaisha: Below 100 CFUs program for EU medical [00:01:30] cannabis. Now that's in the eu. You guys have any thoughts on that? Familiar with

[00:01:33] Kaisha: that? I'm not familiar

[00:01:36] Seth: with it. Yeah, so What he is talking about is like bacterial stuff. So colony forming units is what CFU stands for. Like in Washington State, you have to be below, I think it's 80,000 for pretty much anything and.

[00:01:49] Seth: It sounds like it's a lot more strict in the EU than here. As far as that goes. I mean, basically you're just doing a test to see what's on it. You go out, people are gonna plate out not your actual weed, but a [00:02:00] surface sample of it. We're gonna see what grows. What do we get? Do we get petritis?

[00:02:03] Seth: Do we get aspergillus? Are we getting, several different kinds of bacteria? Are you spraying compost ts? Is it gonna fail for e coli? What are we looking at? As far as those tests go? I mean, obviously as a medical recreational producer, if you're gonna be selling your product in the US you're definitely required to undergo microbial testing.

[00:02:20] Seth: As far as reasons to fail, go pretty numerous, we can grow our own buds inside that have lots of rot. We can promote power mildew. Like I said, compost. These are a great [00:02:30] way to fail microbial tests depending on your timing and application, just because you're can't really pasteurized compost.

[00:02:37] Seth: Otherwise, we lose all the benefits we get out of it. There's not a whole lot to say out it other than try to keep your facility clean there's probably a few key places you don't ever want to build an indoor or grow facility, or specifically a greenhouse. Right next to a feed lot or any place where you're gonna have a lot of airborne contaminants coming in.

[00:02:55] Seth: That means you're gonna have to spend more money on filtration if you want to grow there. Other than that, yeah, just try to [00:03:00] stay clean.

[00:03:02] Kaisha: Yeah. Thank you guys for that. Yeah, certainly industry standards are varying all over state by state, country by country. But really appreciative of that question.

[00:03:10] Kaisha: One of our attendees, Bill Bow, you posted a couple comments on this, you wanna unmute yourself and speak to it.

[00:03:19] Guest 1: Okay.

[00:03:20] Seth: Yeah.

[00:03:20] Guest 2: I've dealt with this in the past. E G P. It was a big thing. And I think the biggest place that we saw failures was in the design [00:03:30] build phase. So well design phase and licensing. So particular companies would build a facility with the intent of going eu, g n p or shipping to that region. Design a facility based on local ordinance.

[00:03:46] Guest 2: And then, some executives would get a wild idea to go actually complete on E G P. And then you get the E G M P auditors coming in and they point out very obvious things in a tightly constrained regulatory [00:04:00] environment. The one that stuck out the most was not necessarily SOPs changing within the facility, but how it had been constructed particularly around how the air movement.

[00:04:11] Guest 2: Designed in the build, in the ancillary space and then within the growth space itself?

[00:04:18] Seth: Yeah, I mean it, it absolutely affects how you wanna design your system. We've seen over the years, I'm glad you brought up the design build phase, cuz I usually consider that also gen one of your build out.

[00:04:27] Seth: Most people are gonna, with success, they're gonna have [00:04:30] their Gen one build out. Then gen two is like, Hey, let's fix all those shortcomings. Right? And that's a big one. I've seen a lot of people switch away from having shared HVAC systems and also just investing in a lot more fan power to move air around the facil, not around the facility, but around the room while trying to separate rooms within the facility.

[00:04:49] Seth: So, yeah it all comes down to bringing clean air in, if you're gonna bring it in and if you got air inside, making sure it stays clean.

[00:04:59] Kaisha: [00:05:00] Excellent. Thank you. Love this conversation, Bill. But thank you for your perspective too. Excellent. Well, this person also had a second question that they submitted this week. Here it is. What are your thoughts on soaking plugs in a high ec? Range of two to three solution before cloning.

[00:05:15] Jason: It's gonna be a little bit dependent on the nutrient manufacturer and using some of the most common two part salt, which is usually what we recommend right now is two to three's not that high of a range for a lot of what they're recommending specifically for their product at that time.

[00:05:29] Jason: Things [00:05:30] kinda keep in minds. Make sure you are taking a good sized clone so that you get a good head start on the growth of those. Know, make sure that you are soaking 'em for enough duration to get all the AROYA bubbles out and wash out any of the wedding agent in there that's surfactant, that is impregnated during the manufacturing process of that rock goal.

[00:05:48] Jason: So those are kind of some things to keep in mind and, make sure easy or your air p is right on par. Since you don't have a lot of substrate to work with, you wanna make sure that everything is as consistent from plug to plug as. [00:06:00]

[00:06:00] Seth: Yeah. One thing I like to remember is that we've gotta just have a rough baseline for the plants, and a good thing going into veg is to actually do that in a 1.5 to three solution.

[00:06:08] Seth: As far as our rockwool soaking. A big part of cloning though is plant health. How's your mom doing? If you've got an old mom that's getting pretty weak, you're not gonna produce solid clones when you're taking your clone cuts. Also, remember, we're, we want a lot of size consistency.

[00:06:21] Seth: We want to get it as close to the top of that dome as we can. Like Jason was saying, a bigger clones gonna get, be not only a taller head start, but also we've got more plant matter there to work [00:06:30] with. It's more robust, It has more energy inside of that little stick than a smaller one Does.

[00:06:34] Seth: And honestly there's two big things I see in cloning that people typically struggle with. Number one, where you make your cut. I see a lot of people cutting their clones to all of you, right up to having tape marks on their table and say, Okay, these are all gonna be exactly eight and a half inches long.

[00:06:49] Seth: Really, we want to go to the node and actually cut into that node tissue a little bit. So we get a little bit of that axial maritim. That's what's gonna grow the callus for us. Everything below the last, the bottom node on your [00:07:00] cut is gonna, When you clone it, So trim that up. One of the other things I see people struggling with, especially if they're just trying out, rockwool cubes in a tray.

[00:07:08] Seth: Get the plastic inserts that allow you to lift those cubes up outta there, you don't want those sitting right on the bottom of your tray. We want a good air gap in there just to, increase air flow, make sure we don't have any anaerobic conditions. and then actually like the inserts, you can pull 'em out part of the way through your clone run and put 'em into a different tray if you want to.

[00:07:26] Seth: It makes things like water changeouts very easy and gives you that [00:07:30] little extra padding because if that rock wall's sitting on the bottom of the tray and you've got even just a quarter inch of water inside the tray, now we don't have air circulation where we need it, which is down underneath where we stuck.

[00:07:45] Kaisha: Thank you for all of those tips actually, because the next question from Berker 10 15 was, what's your advice for best cloning strategy? Rockwood, I don't know if they met rockwool, clone machine, par trim leaves, et cetera. [00:08:00] Seth and Jason, anything you'd add to the advice you just gave?

[00:08:03] Jason: I, it's gonna depend a little bit on your goals and what your final media is like.

[00:08:08] Jason: Obviously if we're running an aeroponics set clone machines might be a great opportunity for us to not invest any rockwool, just get rid of the media altogether. However, I personally really like rockwool cubes, the, they're very consistent, which helps us get started.

[00:08:24] Jason: The The clones stick in there nice and solid. And one of the things that I recommend as well is you'll see the split [00:08:30] plugs used to be very common. Try to avoid the split plugs if you can. And what you wanna do is just take a. Barbecue skewer or a pin depending on the size, the thickness of your clones and just pop out kind of a quick hole.

[00:08:42] Jason: And not necessarily all the way through the rockwool, but as deep as you'll be putting your clones and try to make sure you're getting all the clones the same depth in that rockwool as well. So those cubes in rockwool are probably my favorite way. Of transplanting. Obviously if you are gonna end up in Coco you can transplant into Coco.

[00:08:59] Jason: It doesn't, [00:09:00] I found it doesn't quite clone as fast as rockwool, and I'm guessing it's just because the poor spacing in that coco itself. And if you are starting off in a rockwool plug, you can still transplant into a cocoa bag just fine. The biggest issues we find when mixing medias is if we've got something like a four by four on top of a gallon cocoa, for example, where we only have, a slight shared surface when we're cloning into something like a cube.

[00:09:25] Jason: By the time that you are ready for the new. The roots have [00:09:30] prolifica almost all the way through that media itself. And so you don't have to get too worried about differentials between the phs that you're running and the way that the hydraulic climate activity is different between the rockwool and the

[00:09:41] Seth: cocoa.

[00:09:43] Seth: Yeah, I mean I, I personally have used rockwool the most like that we can go back in the old days using phenolic foam cubes too, a little bit like rockwool, but you know, maybe a little gross on the environment. Root riots, cocoa plugs are also a great solution if you're going into cocoa.

[00:09:56] Seth: And, like Jason said, he knows a little slower results with [00:10:00] the cocoa. I'll be honest, I work with a lot of guys that do use those transplant into cocoa and once you get kinda the slight different watering hang of it, just because. You're gonna need to water those cocoa plugs a little bit more.

[00:10:10] Seth: Usually they're a little smaller, they don't hold quite as much water. But other than that, I mean, cleanliness is really one of the biggest keys. Always clean your equipment when you're sitting there taking your cuts and, taking off side branches and things. Always clean your tray between moms, between strains, switch out what razor blade you're using, switch out your SNPs.[00:10:30]

[00:10:30] Seth: As far as the actual cut, you. Usually like, try to get at least five nodes when you're taking it off the br the plant. Cut it down, make your cut on the node, Stick it 150 ppp, d a light and 75 or so degrees. And stick that dome on there. Get the humidity up.

[00:10:48] Jason: Yeah, when you're talking about the environment definitely try and build some SOPs in there and take samples across your domes.

[00:10:53] Jason: It's not super likely that you're gonna see huge differences from dome to dome. If you're using heat mats, like you don't have a completely [00:11:00] controlled environment, make sure that you've got enough data to suggest, Hey, all my heat works, or heat mats are pretty much heating.

[00:11:06] Jason: Clones, identically, or as close as possible for that. So build SOPs as far as what, when you're taking those hoods off, how much you've got your hoods or domes opened to keep humidity in or out. I definitely recommend weighing them as well. So get an idea of, the weights when you need toe.

[00:11:24] Jason: and then, outline that for your team so that they know, hey, here's when we intend these plants to probably be [00:11:30] done from our clone room, and here's the steps along the way. So as we always talk about, build some tasks in a harvest group and get a tablet post up on the wall. Encourage your team to use AROYA on the app and just keep him up to date.

[00:11:43] Jason: Do everything that you can. Their job is easier to stay consistent. If we've got too much mental going on there, you have lack of communication between employees. All that type of stuff can be really hard on following SOPs. And that's, I think, kind of the [00:12:00] real goal of o AROYA was to pair people with more information to function proficiently as possible for the.

[00:12:08] Seth: Yeah, and I think you, you really struck on it there, building those SOPs and then organizing it so you stay consistent. You know those clones every day you need to send someone in there to look. You gotta check on all of them. We want to be after, day two, three burping pretty regularly.

[00:12:21] Seth: We want to get some oxygen moving around. We want to take care of those. And part of it honestly, is environmental sensing. So if I'm looking at what's happening in a [00:12:30] 24 hour period, like, man, hey, I'm. It's taken me like three weeks to get through these clone runs. What the heck's going on? Suddenly I find out my temps dropped to the low sixties at night, every night.

[00:12:40] Seth: Like, okay, well slowing down metabolism for half the day every day. Wow. No wonder it takes an extra, 50%.

[00:12:48] Jason: Yeah, I mean, there's a couple more things in there. Like you're talking about trim leaves. I don't personally find it necessary. As long as you're not taking too big of of biomass chunk out of that plant, you don't need to [00:13:00] trim those leaves it in a good ideal situation where you're hitting the VPDs that you need, hitting the par that you need, you should be able to absorb, enough.

[00:13:10] Jason: Nutrients, water from that substrate that you're not running, that the plant dries. So, it goes back to those SOPs when you are doing a specific. So p for a strain. Keep in mind, all right, let's try not to grab more than this amount of of leaves when we are cloning. And that's gonna just help you be more projectable, more predictable.

[00:13:29] Jason: Your [00:13:30] sales team's gonna like you more. Your coworkers are gonna like you more because they get to treat all the plants the same. And obviously, if you check out a video about consistency growth behavior. Basically it just talks about how lucky we are to be working off of clones simply because the genetic performance from cut to cut should be very similar.

[00:13:49] Jason: Whereas obviously if we're working out of seeds, maybe we're doing some pheno hunting that consistency's not to be expected like it would from a.

[00:13:59] Kaisha: [00:14:00] man, dropping the knowledge today. We're just to let y'all know, we're gonna be sure to get a link to Jason's video and share that with the community, but man, nothing.

[00:14:07] Kaisha: Jason, thank you so much for that excellent breakdown to our live attendees today and we got a lot of them. It's so good to see all of you. We wanna know what questions you have. Be sure to drop those in the chat so we can get Seth and Jason to address those in real time. But I'm gonna get it over to Mandy.

[00:14:20] Kaisha: I think we have a right in.

[00:14:22] Mandy: Oh yeah, totally. So yeah, we had a ride in this week from our friends over at River City Growers. So they wanna ask Seth and Jason what's the line between a [00:14:30] drooping thirsty plant and a wilting plant?

[00:14:34] Jason: Yeah. So I'll get started just kind of with the science behind that.

[00:14:38] Jason: And so when we are talking about what those lines are, it's gonna be usually related to the matrix, potential characteristics of your substrate and the health of the plant, right? So kind of two factors when we think about plants that begin to drip, what is going on is the cell. Lose an amount of trigger [00:15:00] pressure, and there can be a number of reasons for this.

[00:15:02] Jason: It could be a cause of environmental factors. So the trigger pressure is low because we're too cold or too hot, or not enough humidity. That's why we always talk about vpd, hit your VPDs and most of the time that's gonna help that plant. Rigid tooker pressure in itself.

[00:15:17] Jason: And when you jump back into substrate stuff, when we talk about tooker pressure, we're looking at the matrix potential. If the plant has to apply too much vacuum to pull water from that substrate, those cell. Walls are [00:15:30] gonna lose their rigidity and your plant's gonna begin to Dr. So you, when we talk about people's plants are praying, that means that the tucker pressure is nice and rigid and the plant is acting well.

[00:15:42] Jason: Right? And another factor we can talk about is osmotic potential, which can affect tooker pressure as well. It's probably a little more advanced topic that we use sometimes when modifying electrical connectivity, the nutrient levels at different stages in the plant. What those lines are specifically.

[00:15:55] Jason: Easiest way to kinda get a start on that. If you've got good, healthy plants, your environment's on [00:16:00] par and stuff look up the matrix potential curves for your specific substrates. So you're in something like Coco, it's actually gonna have a little bit of an elbow, usually between, say, 20 and 25%, depending on the manufacturer and the pit chip size from that manufacturer.

[00:16:16] Jason: And something like rockwool is very. And so when we look at rockwool, as long as the other factors are right, the substrate can get very low in water content before the plant actually feels a stress due [00:16:30] to a high matrix or very low matrix potential, if you will, a high negative potential. So since.

[00:16:36] Jason: Major potential is the vacuum that's being applied. It's gonna be usually a negative kpa. And so it's actually one of the ways that most traditional crop growers evaluate their their soils. So if we're looking at subsurface drip, maybe, some corn in Colorado, for example, they will use something called a 10.

[00:16:54] Jason: For evaluating what the matrix potential is, or excuse me, the that vacuum lever level is in the [00:17:00] substrate. So, that was kind of the in depth ways to evaluate it. Sorry if I was not general enough.

[00:17:07] Seth: That's okay. I think one thing we should talk a little bit about on this though is a difference between wilting point and permanent wilting point and looking at different medias, and that's really where the rubber meets the road here.

[00:17:17] Seth: When we're talking about rockwool, like Jason said, he can go down extremely low without actually wilting the plant. Just because it has a low matrix potential, the plant is not having to pull. That water outta the soil or the media. Other or other media, [00:17:30] we're talking Coco. Yeah. It might be closer to 1215, even up to 17.

[00:17:34] Seth: And it's also gonna range by strain. One important thing to note though about wilting point in general is that in this type of system, we're never trying to approach that typically permanent wilting point is something we'd look at more in, in ground crops and we'd be looking at, okay, how.

[00:17:50] Seth: If we're looking at a vineyard, for instance, how dry are we gonna get it to put enough generative stress on these grapes to bulk fruit production and not leave production? So the practical application of wilting point in what [00:18:00] we're doing is if you think your plant wilted, you messed up, you got it too dry, Or we're looking at, Hey, do we have any fusarium issues?

[00:18:08] Seth: You can see the same kind of symptoms with a. Just because all the plumbing going up to the plant is clogged. Essentially, when you've got bacterial infection at the base of the plant and in your roots, it's not necessarily, disease symptoms. You're gonna see up top. It's starvation, it's wilting.

[00:18:21] Seth: There's no water. When the pipes are plugged, nothing can get up there. So I think it's important to look at like, Hey, we, there's a lot of talk about plant [00:18:30] stress inducing morphological changes. And while that's absolutely true, we're not stressing it in the same way that we would traditionally talk about, like let's say drought stress in corn.

[00:18:40] Seth: There what we're doing is if we have a drought stress trial or a PWP trial, we're gonna go out to the field, see how dry we can get it, and at what a certain point 50% of my plants are gonna die. And I go, All right, on this variety. Just like with drugs, LD 50, that's what we're calling a permanent wilting point, because over 50% of plants that I expose to this.

[00:18:59] Seth: Are gonna [00:19:00] die and they won't recover. So yeah, again, just to stress, we never want to hit that cannabis cultivation nowhere even close.

[00:19:08] Jason: Yeah. And one other factor there as well is nutrient composition. So, I get a lot of questions about, people send me a picture of their leaf and like, Hey, what's going on here?

[00:19:16] Jason: I've got clawing or veal, chlorosis, and. It's really hard to tell specifically what that's trying to say. If you do have other symptoms that suggest nutrient imbalance, send it in for a leaves issue [00:19:30] analysis. They're fairly inexpensive. The companies typically get around to you pretty quick and they'll give you an idea are which which components of your nutrient, which elements in there are out of expected ranges for cannabis.

[00:19:42] Jason: So, that, that would be kind of one last one that you definitely, probably should be doing anyways, just. Tabs on what different strains are eating. But definitely, absolutely. If you have any concerns that that are related to

[00:19:54] Seth: composition. Yeah. And just to follow that, I've been encouraging people to use tissue sampling [00:20:00] quite a bit.

[00:20:00] Seth: One thing I do run into though, is certainly in a a fear and an obsession when they find out that they have a potential deficiency. One really important thing to remember is like if you're already getting decent results with a fertilizer and you've got one strain that just doesn't like it, or this run sucked or whatever.

[00:20:16] Seth: Most fertilizer programs out there, most that I've encountered anyways, are fairly complete. By the time you've got a schedule put together, usually you have everything. And if it didn't work at all the first time, that might be a sign that you're doing something wrong. Cuz generally, [00:20:30] even if you go take these tissue analysis samples to a crop nutrition consultant for.

[00:20:35] Seth: The answer might not be some secret sauce that you're missing out on. Usually it's correcting pH and feeding strategies and then upping or lowering your feet. A lot of times it's not that you're missing anything special, it's just that strain wants more calcium so we gotta up the calcium nitrate to get at that during stretch or, it's usually a lot more simple and I just wanna stress that, people shouldn't get scared of those tissue analysis results at.

[00:20:59] Seth: [00:21:00] and really look for simple solutions before trying out like some new wild product that you've never tried before, three quarters of the way through the run,

[00:21:07] Jason: so you're telling me I don't need six different additives to achieve the. Best production.

[00:21:14] Seth: Yeah. Yeah. don't sell fertilizer, but you need a lot of sensors in internet.

[00:21:18] Seth: I can tell you that.

[00:21:21] Mandy: Yeah. Thank you guys for that. Yeah. We have the questions rolling in over on YouTube, so Yeah, I'm gonna get to those. I feel like this is a good segue. So Diane is writing in, Hey, good to see you [00:21:30] again. So he wrote, last time Seth was talking about calciums, but he didn't mention anything about calcium sulfate.

[00:21:35] Mandy: What are your opinions on that?

[00:21:40] Seth: Typically, unless you have some kind of huge sulfur deficiency, that's not something we need to supplement. I would tend to stick with calcium nitrate, particularly for supplementing you it's definitely an option to play around with. I would be careful in that, when playing around with deviating from what's considered more of a standard mix, just because.

[00:21:57] Seth: You might run into things like amcal nitrogen that do [00:22:00] not play well when dissolved with other things, and that being the reason for that amcal nitrogen is very low nitrogen content and it acidifies your solution very much so, like you're gonna end up battling yourself and spending more money putting in certain amendments, whereas, sticking with what's tried and true and works.

[00:22:17] Seth: And like I said, sometimes if we're talking a calcium de. throw in some good old Cal Mag, raise your ec. Sometimes we, sometimes, like let's say you've been riding a high EC for a while and we've got a steep drop off. [00:22:30] Okay? If we take a tissue analysis test, when those leaves yellow out, it's gonna show us deficient in a bunch of things.

[00:22:35] Seth: We're not actually that deficient in our feed, it's just that we stacked it up and then dropped it off, and now the plant is struggling to uptake water because we've changed the osmotic environment so quickly.

[00:22:45] Mandy: So yeah, we have another question over on YouTube. Salty r says, Thanks. Thanks guys for these podcasts. We love 'em. I was wondering, what are some cues you'd suggest to make the plant stack harder and flour under hps?

[00:22:57] Jason: I mean, I'll check off the [00:23:00] basic easy ones. Make sure your CO2 concentrations, CO2 levels in the room are in corresponding to your light levels.

[00:23:06] Jason: Make sure your light levels are nice and high. Make sure you've pushed that plant with some of the crop steering techniques that we consistently talk about through these episodes. Those are the ones to check off that are.

[00:23:19] Seth: Here's another one. Go for your shorter veg and don't top, go with a little bit smaller, more manageable plants.

[00:23:24] Seth: Maybe you're gonna end up with more of 'em. But if I take a plant that I've only grown to like 14 inches [00:23:30] tall and flip it, it's got, a smaller space between nodes at that point coming out of it, and that even leads into if we're really trying to get it to stack, that starts way back in.

[00:23:39] Seth: We're going for more generative style and veg if we've got a plant that's really trying to take off and just trying to keep those inner nodes short when we flip, if you're back there flipping a two and a half, three foot doll plant it's gonna be hard to get that to stack as well.

[00:23:51] Seth: It's just a game of proportions. If we say this plant's gonna double in size, pretty much every aspect of these inner nodes, well, bigger inner node is [00:24:00] way bigger when you double it, so, basically just, follow your program all the way through and don't let up on your generative attack. I'll say in the beginning, trying to fight that stretch,

[00:24:10] Mandy: awesome. Thanks guys. You'll have to let us know if you have any follow-up questions, but yeah, that's it for our YouTube for now. But please send in your questions. So Kaisha back over

[00:24:17] Kaisha: to you. Awesome, Mandy. Thank you so much. All right. Our next question from Instagram is submitted by Can Sutra og.

[00:24:25] Kaisha: They have a sensor question there. One wondering why does my terrorist 12 SOLAS [00:24:30] combo read 100% vwc in rockwool sometimes? Any thoughts on that?

[00:24:35] Jason: That's kind of weird. I, are you inserting the sensor to love? Possibly. Usually in rockwool we'll see the field capacity and say that's 60 to 70% range, sometimes up to 75%.

[00:24:48] Jason: So, that's definitely a little different. Might have to chat with you to get more specifics on the process. You are installing the.

[00:24:55] Seth: Yeah, absolutely. Please hit us up either of us would be really happy to go into that with you. [00:25:00] Typically, yeah, we don't see that high of reading. There is one case though, where I've been pretty stumps for a while and then someone sent me a picture and it just clicked for me.

[00:25:07] Seth: If your tray's not totally level and you've got a slab in one on one end of it, and it's not actually draining off correctly, you just have a slab that's constantly, there's a puddle underneath it, then you might see something like that. But otherwise, yeah. Try replacing the sensor, moving it to a different slab and try to determine if it is, if it is a sensor problem, again, talk to us.

[00:25:27] Seth: But if you move it to a different slab [00:25:30] and it reads something more normal, it's like, okay, well are we dealing with some sort of irregularity in this particular slab? We might be looking at that. That definitely happens.

[00:25:42] Kaisha: Awesome. Yeah, kinda kinda suture og if you see this and you, you still stump.

[00:25:48] Kaisha: Definitely hit us up on Instagram and let's see if we can figure out that issue. Send us some pictures. All right, I'm gonna keep on going here. Lot key submitted a question through Instagram. They [00:26:00] wanna know when running a perpetual harvest in a large glass house, what sort of night temperature difference and vpd range would you target?

[00:26:09] Jason: Ooh, that's gonna be the tricky part of perpetual harvests. Obviously, when we have young plants and old plants, it's a lot more difficult to tailor the day night temperature differentials. And the ideal V p D ranges, So usually young plants will be a little bit lower vd, we'll keep those daytime [00:26:30] temps nice and high.

[00:26:31] Jason: Nighttime temps will be pretty close, daytime temps. And then obviously towards the end of the cycle we're shooting for a little bit higher vd, mostly to avoid mold growth bacterias, that type of stuff. And so you gotta make the. Consideration that you can if we have big night day differences, we're gonna help induce an signin production towards the end of flowering as if we've got those on our younger plants, then we're gonna have a little bit [00:27:00] less little bit less fast in the production of it as that.

[00:27:03] Jason: Yeah,

[00:27:03] Seth: we're gonna end up with a smaller plant. You're gonna slow it down during stretch and not produce as much biomass. So I can answer that actually, do it. You're gonna end up running about 74 to 77. You might get a four or five degree overnight, diff, ideally, and probably 1.2 to 1.4 v p. Maybe down to 1.1, but just like Jason was saying, you're gonna have to pick trade offs.

[00:27:25] Seth: If you want to get your NUS to purple up, well, you're gonna be dealing with [00:27:30] smaller plants. And then the next step is, you mentioned glasshouse, which I don't know if you're in England, that's where I've heard the term glasshouse a lot more than greenhouse. But anytime we are talking about a greenhouse obviously the outside environment is a huge factor.

[00:27:42] Seth: Do I have the energy to actually keep that temperature up? We might be talking like about something that you can't even really achieve here. Like maybe if you can get it up to 68 at night and that's all you can get in the winter, well that's what we're going for. And that's, anytime we're talking about greenhouses and the bigger they are, the [00:28:00] more we need to count on there being a variation in harvest related to the time of the year.

[00:28:04] Seth: If we're talking a really small hybrid greenhouse that has mixed lighting, pretty self-contained. Yeah. That's basically a high tech grow room. If we are talking, 10,000 plus square feet yeah. Every yield's, every harvest is gonna yield a little bit differently and every run is gonna be different because when we're never gonna be able to recreate perfectly our nighttime times.

[00:28:23] Seth: Yeah. And run

[00:28:23] Jason: some time series. Sampling of your environment across that greenhouse. So, just,[00:28:30] from my experience, I was running in 40 by one 20 greenhouses and it was all horizontal airflow, right? So we had pad pump. On the front end of it and exhaust fans on the other end. And we almost always had a lot more heat at the exhaust end, right?

[00:28:45] Jason: As our solar radiations building up in that room, we're gonna collect heat in there. And so, let's say that was the perpetual harvest, we would probably want the young plants towards the exhaust fans where we have a little bit higher temperature, a little bit lower differentials, and move 'em towards the [00:29:00] front where we can take advantage of some of those temperature drops when the pad is opening.

[00:29:06] Seth: Yeah, all the greenhouse fun. Why does purple punch turn purple at the front of the room and never at the back ? So, yeah, I mean that is one of the fun things about a greenhouse though, is you do have all these dynamic things going on that you can, are a challenge. But as Jason pointed out, sometimes you can take advantage of that.

[00:29:22] Seth: Just like, I love having a greenhouse for a veg bay too, for instance. Then I can work in there in the morning without my lights on and then [00:29:30] kick those off a little later in the day and be comfortable. Is it perfectly consistent, Ppp d eh, probably not as quite as if I had a lamp on it all the time, but guess what?

[00:29:40] Seth: That's kind of a little benefit of getting to work in that system. Everyone in the flower rooms is sweating and everyone in the bedroom is nice and comfy.

[00:29:49] Kaisha: This was such a great question. Lock, we don't know where you're located. You'll have to let us know. But if you're in Europe, I love how talking cultivation is.

[00:29:56] Kaisha: It's global. It's international, so we are gonna keep [00:30:00] the party going. Mandy, what's happening on YouTube? Oh

[00:30:02] Mandy: man. We have a ton of shout outs and we have a lot of questions coming in. Yeah, I'm just gonna start at the top. Hoffman's choice. I think we've gotten some questions from you before. Nice to see you again.

[00:30:11] Mandy: They wanna know I recently installed pressure compensated. Drippers and my existing submersible pump is heating up the reservoir due to increased feed times, any external pump or booster brand recommendations.

[00:30:26] Jason: I mean, I like Grundfos equipment because it's been in the industry for a [00:30:30] long time.

[00:30:30] Jason: We see dab pumps all over the place. anything that's probably not specific to cannabis growing is what you're gonna want to use. Anything that's getting used in other industries is a great way to go.

[00:30:41] Seth: Yeah, and I mean, one thing we've found, just like your pressure compensating emitters, those weren't designed for cannabis either.

[00:30:46] Seth: Those have been poured over from the vegetable production industry and nursery industry. Like Jason said don't focus on cannabis specific ones, but at the moment, if you go to any number of hydro stores or online distributors, you will see [00:31:00] dap. You'll see gr fos, you'll see several of the same pumps.

[00:31:03] Seth: You get to the smaller end of things, like kinda more towards the home or boutique sub 2000 square feet, you might run into like the little giants. But basically, what you wanna look for is. You might wanna avoid a pump that's got, some kind of uncoated cast iron housing, for instance, cuz we're running salt water through there.

[00:31:20] Seth: So you wanna make sure you've got enough power. Probably a couple of horse depending on how big your system is. But really just look for a quality pump that has quality components and isn't gonna corrode on you. [00:31:30] That's the biggest enemy of everything here is rust. It's the one metal part in our system that can, and if you buy the wrong one, it will.

[00:31:36] Seth: And if you wanna see some plugged injectors, you think your salts do something. Wait till you get rest in your. All really

[00:31:44] Mandy: good notes and things to keep in mind. Yeah, Hoffman's choice. You'll have to let us know if you have any follow-ups. Yeah, going down our list. Diane wants to know. I don't wanna use calcium nitrate cuz after five week five and flowering, I don't need that much nitrogen, but I need calcium for sure.

[00:31:58] Mandy: So how am I going to be able to battle

[00:31:59] Seth: [00:32:00] that? Gotcha. Calcium silicates, another available supplement. I would strongly I mean, unless you've got some tissue analysis results to back you up and I looked at your entire feed chart and everything, including your graph of a whole grow, so I could see where you see was doing in the root zone.

[00:32:16] Seth: I wouldn't immediately put just seeing spots on. As a calcium deficiency, like, or should I put it doesn't mean it's deficient in our feed. It means our delivery strategy may not be sufficient for the plant.[00:32:30] For instance, a lot I've run to a lot of people that are running a few different brands that do have calciums supplemented in them and that they'll be adding cow mag and just having all kinds of problems cuz what they're, attributing to a calcium deficiency isn't one.

[00:32:43] Seth: They're just running in the wrong EC range or like, Hey, what's your runoff pH 4.9 to 5.2? Okay, well, everything's deficient at that point, so immediately going to that one supplement isn't always gonna get you there. At Diane, I would always probably try to raise my root zone EC [00:33:00] and get that root zone visibility before I just assume that this plan has a problem.

[00:33:03] Seth: There's a lot of ways to mess up a plant, building up to actually seeing that symptom.

[00:33:11] Kaisha: It's such a fine

[00:33:12] Mandy: line that you walk. Yeah. Thank you for that, Diane. Back over to you, Kaisha. We got some live questions coming in.

[00:33:18] Kaisha: Yes. All right, Mark, drop the question in the chat. Mark, do you wanna unmute yourself or I can ask for you?

[00:33:29] Kaisha: I'm just gonna [00:33:30] go on. I'm gonna just go for it and if you have anything you wanna chime in on, feel free to unmute yourself. Mark wrote in an indoor L e d setup around 30 feet by 50 feet. What would be your preferred air movement setup? Oscillating fans, V flow fans, axle type fans, racetrack pattern, et cetera.

[00:33:48] Kaisha: Thanks guys. Thanks to your question.

[00:33:51] Jason: So, this might be a little bit personal preference. There's a lot of different solutions that can get you good air mixing in there. My favorite way [00:34:00] is HVAC sox especially for an indoor, where you already have an HVAC system outside of the room. And, you've got ducting vents going into there, get some HVAC socks.

[00:34:10] Jason: Basically they're gonna distribute that air very well so that you have consistent airflow across there. And then, if you do see vertical stacking of heat I like some carpet pans. Every once in a while under the benches, if you do run into a lot of vertical varis,

[00:34:24] Seth: yeah. I mean, the carpet fans are great.

[00:34:26] Seth: I'll definitely, Well, I won't tell a story about 'em, but be careful with those [00:34:30] yeah, you nail it with the HVAC socks. Those are like pretty much the bees knees in this business right now. They're easy to put in. They're not in the way all the time, like hard venting. And then once you start running 'em, you'll realize, hey, I've got pretty even pressure across all the holes coming out of this sock.

[00:34:47] Seth: Versus, with my oscillating fans, like, don't really get even coverage after about five feet away from 'em. Really that sock is gonna be your best friend. And then carpet fans for the floors are all right. I think the big [00:35:00] thing is having enough fans and that's. That's where the sock comes in.

[00:35:03] Seth: If I have one huge one, I can distribute that. Otherwise, the equivalent might scare you to move the same amount of air with some oscillating fans and get it to where you're going to go. And then if we're talking like lift fans or V flows, anything like that, if I'm 12 feet in the air with that, I've only got so much efficacy.

[00:35:20] Seth: So that's really the thing to keep in mind is like we want the source of. Maybe not the, what generates the moving air, but the, wherever the air exits the fan or the duck, we [00:35:30] want it to be as close to the plants as we can get it for actual, efficacy.

[00:35:34] Jason: Yeah. And, you've got an advantage already with running on LEDs, so you've got less localized heat than we'd see from hpss.

[00:35:40] Jason: So probably not quite as much vertical heat stacking as we'd see in more traditional h hps setups. Another advantage of those HVAC hawks is they're diffuse. Air movement. So when we're running oscillated stands, for example, lot of times we're gonna have to have plants that aren't so close to avoid wind burning.

[00:35:58] Jason: You have maybe where you're gonna run into [00:36:00] wind burning anyways. Now you've got lack of consistency across your canopy. All those types of things. So that defused is just a really nice way to keep gentle movement throughout the entire space as consistent

[00:36:12] Seth: as possible. Yeah. And if, there's two things I like to look at too.

[00:36:15] Seth: Whenever we're talking about these equipment upgrades economics, Am I gonna buy 20 oscillating fans? Cause that's gonna be a lot more expensive than that sock. And then how much wire am I running to power all these things? So that's, there's a few logistics to think about.

[00:36:28] Seth: If I have to go add 15 [00:36:30] outlets to. That really jacked up my building cost quite a bit, especially associated wire. Hopefully I have enough space in the panel. We're already using a lot of power here. We don't wanna take it for things that aren't directly producing us money. Like more light makes me more money, more airflow.

[00:36:45] Seth: It's good for my plants, but not, it's not the same correlation for power usage.

[00:36:49] Jason: Plus fans are really fun to clean, so, Oh

[00:36:51] Seth: yeah. Yeah. There's that side too, right? That was a joke. No more taking apart your fans, oh yeah. And those socks, I mean, [00:37:00] I've seen people clean 'em. I've also seen there's some cheaper ones out there you can buy and throw away every few months,

[00:37:04] Jason: yep. Some of 'em you can throw in the laundry machine. Yep.

[00:37:09] Kaisha: fans, you can throw in a laundry.

[00:37:11] Seth: It's just it's a sock. It's just a long tube that inflates and has a bunch of little holes in it. Okay. Yes. Yeah. All right. But no cutting yourself, setting it up either, yeah. Wow. Science

[00:37:21] Kaisha: is cool. Really that Mark, thank you so much for that Excellent question.

[00:37:26] Kaisha: I don't think we've met you before, so if you wanna be in our raffle. [00:37:30] Please feel free to drop your email address in the chat. All right. Sending it back to you, Mandy. We got more from YouTube. Yeah.

[00:37:36] Mandy: Awesome. Yeah, the questions are rolling in. Diane did have a follow up question. So he wants to know what's the difference between M P K, mono potassium phosphate and m a p mono ammonium phosphate?

[00:37:47] Mandy: Also, if there are any benefits to use something else like poly potassium phosphate, let me know if you want me to drop that question in the chat, guys.

[00:37:54] Seth: Sure. I'll be honest, I usually avoid anything that's a maniacal when we're talking about [00:38:00] hydroponic solutions. Beyond that, I don't have the most experience to answer that question, to be perfectly honest.

[00:38:06] Seth: I'm

[00:38:06] Kaisha: sorry, Seth. What was that word you just said? A maniacal.

[00:38:10] Seth: Yeah. So like if we're looking at mono ammonium phosphate, that's like n H four. I can't remember the rest of it, but anytime you see ammonia, you're gonna have, a four to one ratio of hydrogen ions to nitrogen ion. Thus, you're gonna really increase the acidity in your solution.

[00:38:26] Seth: That would be the main effect of that, but you're not getting much nitrogen [00:38:30] either.

[00:38:33] Kaisha: Got it.

[00:38:34] Mandy: Awesome. Thanks for that. Yeah. Diane, let me know if you have any follow ups. We got a second question from Iron Armor. So what type of rudin irrigation strategy would work well with stacking a four by four rockwool cube on a six inch Hugo Day, one of flowering, I noticed the bottom block wicking out the moisture from the top.

[00:38:55] Jason: Yeah. So, that's probably a little bit more tricky of a Rodin process just [00:39:00] because it's not necessarily the best combination for larger plants. You've got a fairly tall vertical stack. But for some of the Rodin processes you're gonna do very similar to like we'd be doing in Slabs or onto cocoa.

[00:39:12] Jason: And you're gonna want, number of multiple shots a day that are pretty small. If you do see that lower block wicking, you might have to up the number of shots a little bit just to make sure that the plant's got some water up in that top block and you're not losing it all to hydraulic movement into the lower.[00:39:30]

[00:39:30] Seth: Yeah, I think that's an important thing to remember. After this transplant, obviously you want to have your drippers in that top block, but also be aware that your water content, your field capacity in that top block just dropped from 65 to about 35 so all your water moved downwards. There's not gonna be anything special going on, although if that's gonna be your growth strategy.

[00:39:51] Seth: Just a little tip. You might want to plant directly into the six by six by sixes and save some money on the Delta tens because you're not gaining an [00:40:00] appreciable amount of water holding capacity by going with the Hugos versus a Unilab or anything else. Great advice. Great.

[00:40:10] Kaisha: Awesome. Yeah, it, you guys

[00:40:12] Mandy: always have great advice.

[00:40:13] Mandy: Yeah. On Iron Armor. Let me know if you have any follow up questions. Other than the awesome shoutouts that we're getting from East Coast from pretty much everybody who's chatting in I think those are the questions for now, so I'm gonna pass it back over to Kaisha.

[00:40:25] Kaisha: Thank you so much, Mandy, shouting back to you Oliver on YouTube.

[00:40:29] Kaisha: So good to have [00:40:30] you. All right. And just letting all know everybody who's on live with us today. We've got about 15 minutes left, not too late for you to speak to the experts. I'm gonna keep it moving with our Instagram questions here. Casey Garcia wrote in, How do you set your maintenance feeds? Thoughts on that?

[00:40:46] Jason: Yeah. So let's start off with substrate size and transpiration plus evaporation rates, right? So I did this just the other day for a client that was doing crop steering class four and looked at, alright, [00:41:00] you're losing about 3% water content per hour during photo period on and about 1% per hour photo period off, right?

[00:41:07] Jason: And so then we can evaluate if we're shooting for. Say 15% maintenance, dry back, then this will be the irrigation window that we need for that size of substrate based on our water holding capacity. And so that, that's gonna be kind of your first constraint is, All right, what can we do to achieve the dry back that we're hitting the need.

[00:41:26] Jason: In, in their case, they were a little bit too small a substrate, and so [00:41:30] they weren't able to run a short generat. Irrigation schedule. So for any of the more vegetative, they're, the maintenance shots were pretty long. So that's the wide outline. As far as the number of irrigations definitely related to your drippers eyes.

[00:41:45] Jason: If or. Emitter rate would be the most appropriate, sorry to say that. So it, if we've got say two gallon per hour drip emitters, that's gonna be a lot faster water flow than we would like, and we'll need to break up our maintenance and probably [00:42:00] even our initial irrigations into shorter irrigation durations so that the.

[00:42:06] Jason: Capillary effect of the substrate can basically wick out the water before we start just running off because of

[00:42:13] Seth: that flow. Yep. We don't want cohesion or gravity to overcome cohesion before it exits the bottom of the block. Yeah, I think that you covered it pretty good there, dude. Yeah.

[00:42:22] Guest 1: Excellent.

[00:42:22] Kaisha: That's an excellent run. Rundown. Hopefully Casey. Has everything they need to know to to do their maintenance feeds on their end. [00:42:30] Excellent. All right. Gonna keep it moving here. We gotta write in from chubby factory ca. They're looking for some guidance when transplanting from one gallon quick fill bag to two gallon.

[00:42:40] Kaisha: They're wondering when to change the placement of the serves.

[00:42:44] Seth: Well, when you pull it outta the old pot and put in the new one, you're gonna wanna stick the new pot. Back to the, Delta 10 and the Hugo question, though, you're gonna get a lot better performance shortening up your veg by switching to like a three gallon cocoa pot, rather than going from a one to a two gallon with [00:43:00] that one gallon pot.

[00:43:00] Seth: We're looking at, More like a 10 to 14 day root end time before we can actually start hitting it quite as hard with our P one s. Whereas with that smaller pot, we're gonna get a faster root end period and also not have as much media to sling around the facility.

[00:43:16] Guest 1: Okay.

[00:43:18] Kaisha: Great. All right. Keeping it moving through Instagram.

[00:43:21] Kaisha: Folks are wrong with us. You still got a little bit of time. Ask your questions both in the chat. No. Middleman wrote in would dry back. I think they mean drying [00:43:30] back. My living soil mess up the life of the soil.

[00:43:35] Jason: Probably not. I mean, especially if you're within the dry back parameters that we talk about you're still gonna have moisture available to the organisms in that substrate.

[00:43:44] Jason: So I wouldn't get too worried about it unless you're, you're going of and dry which your plants aren't gonna like, so it's gonna be worse for your plants than the substrate itself or the soil itself.

[00:43:55] Seth: Yeah, I mean, I think the biggest factor there is looking at. There's a lot of talk out there [00:44:00] about what living soil is, and the reality is we're dealing with soil ex soilless mixes with organic amendments.

[00:44:05] Seth: So when you look at your living soil if you're constantly having to replace, if you're re inoculating or anything like that, regularly, Then you know that's gonna have a lot more effect on your plant health than drying back naturally in any given system, we're gonna have a dry back, right?

[00:44:22] Seth: It's not raining 24 7. So therefore we see, some range. That's why like when you see, an EC range, okay, it's not static. Like no it wouldn't [00:44:30] be. Cuz even in nature the ground's always slowly drying out and it fluctuates. So, yeah, go for it. Go for those dry backs, just like you're outside, but one thing to remember, if you are working with a living soil, quote unquote you're probably dealing with a peat or coco based mix. So you're gonna wanna run some of those same water content parameters, figure out where your field capacity is. Are you looking at 35%, 45%, 55%? And then say, Okay, I'm not gonna plan on [00:45:00] going below 2020 5% just for.

[00:45:02] Seth: It's if you are dealing with a soil that has some CEC and actually has some clay particles and things like that, then it starts to get a little more complicated on establishing where that wilting point would be. Like we were talking earlier, that's kind of where the, all that comes into play.

[00:45:21] Kaisha: Wonderful you guys. Thank you so much. All right. Running a last couple of Instagram questions here. Kevin Greens wrote in, I'm running well, H two [00:45:30] oh. Is it more important for me to use hydrochloric acid in my water?

[00:45:34] Jason: There's, I'm guessing you're talking about how to pH the water more than trying to treat

[00:45:40] Seth: it.

[00:45:40] Seth: He's talking about sanitizing. Hypochlorous has been pre popular lately especially in some people that have water quality issues, like the fu serum contamination and stuff. So how dirty is your, Well, let's start there. What kind of PPM is your well water coming out at? Is it full of carbonates?

[00:45:56] Seth: Is it alkaline? What's the pH we're looking at? That's kind of the basis there. [00:46:00] Well, water can be really great and it can be not so great. I mean, around here you can drill a 30 foot well and get some pretty gross water, or you can drill a 200 foot well and get some amazing water. So I.

[00:46:11] Seth: Yeah, that's a really broad question.

[00:46:13] Jason: I would say best thing you can do, send some samples in for water analysis and you'll get an idea of what nutrients are already available in the water, and then maybe what contaminants you might wanna be worried about, and that's why you're treating

[00:46:27] Seth: it. Yeah. You might be surprised to come find out that you [00:46:30] have 0.3 ec of things that you actually want in there, and you can save a little money on your mix.

[00:46:37] Guest 1: Awesome.

[00:46:38] Kaisha: Alright. Gosh, somebody's coming in. I love it. We're still going, we're going in hot in the last few minutes of Office Hours this week. Live attendees type your question in the chat. Now's the time. I got this one from Instagram, Peter Birch, I think I messed up your name. Sorry, Pete.

[00:46:51] Kaisha: They wanna know what is the cause of little green. Not fully formed and usually have more than two sides. Seth and Jason, you ever seen [00:47:00] that before?

[00:47:01] Seth: Yeah, late stage from aphrodites. So basically you're having either an EC problem, heat problem, or some other stress related issue potentially. Or you've got a strain that's an F one hybrid off of two female plants.

[00:47:14] Seth: So just by breeding two female plants, we've pre-selected for a plant that's gonna throw manners. if that plant starts throwing STAs in week, six, seven, that's not enough time for any of those seeds to actually. If you're actually out there looking for seeds and you're, you.[00:47:30]

[00:47:30] Seth: digging through your crop, looking for 'em, you made some crosses. The actual seeds that you'd want are gonna be down deep in the flower, close to the stem. They're gonna be those earlier galaxies that you want. Those late ones, like I said, that's just you. You gotta plant hering out in there. And You probably missed it somewhere.

[00:47:46] Seth: Yeah, just didn't notice it during the takedown. That's the, And it's probably right next to that one bud that's just loaded with seeds, that's usually how it works.

[00:47:56] Kaisha: Never a dull moment in cannabis cultivation. Is there, [00:48:00] All right, Billbo typed a question. You wanna go ahead and ask it Billbo?

[00:48:07] Seth: Sure.

[00:48:08] Guest 2: It's back to these tiny pots that I was incessant on running.

[00:48:12] Seth: So yeah, it happened. I'm now having to irrigate once

[00:48:16] Guest 2: approximately seven hours. After the P three has started that brings the volumetric water content up to a palatable range, and then shortly before light's on, I'm getting another [00:48:30] notice letting me know that I'm getting into that range again.

[00:48:33] Guest 2: I'm

[00:48:33] Seth: wondering,

[00:48:35] Guest 2: is there some strategy that I have? Thought of,

[00:48:40] Seth: or I mean, really you can, that's out there that has me not doing this

[00:48:44] Guest 2: again, but still maintaining the same

[00:48:47] Guest 1: mix.

[00:48:48] Seth: I mean, if you're stuck on that substrate volume and you want to be able to have more of a gas tank to steer with, essentially you're gonna have to get a smaller plant.

[00:48:54] Seth: That pot's gotta carry less. Plant matter being grown out of it. You, I mean, you can manipulate your vpd, but. [00:49:00] Typically I don't like to tell people, Hey, let's back off on the light and the V P D to the things that are actually really important for biomass production. Without lowering your yields, the only way you're gonna do it is more smaller plants.

[00:49:13] Seth: And by small, I mean there's some people in double stack situations that are flipping 'em. 10 Dave Edge, that sucker's got roots. It gets a 15% dry back, then they flip it.

[00:49:25] Guest 2: Yeah. I

[00:49:25] Guest 1: have not tried that. But

[00:49:28] Seth: usually because

[00:49:29] Guest 1: going [00:49:30] into flop, there's already some, I wouldn't say trepidation, but

[00:49:35] Guest 2: doesn't matter how many times you do it, it's always running new cultivars.

[00:49:39] Guest 2: You never

[00:49:40] Guest 1: actually know how it's gonna perform and trying to yield. In my mind it's easier, not necessarily cheaper, but it's easier to just administer a P three. But going

[00:49:49] Guest 2: forward, running the same cultivars, I don't want to continue that. So your only logical

[00:49:54] Guest 1: conclusion is Molly Plants. Well,

[00:49:56] Seth: that's where we're gonna head.

[00:49:57] Seth: Yeah. I mean, it's and honestly, I do work with [00:50:00] some people who use flood and draining tables and four by four rockwool cubes. Their plants are about two feet tall, two and a half feet tall at harvest, but they're putting 240 to 300 plants in a five by 20 table. So there are ways around it.

[00:50:13] Seth: It's just finding that, obviously finding that plant size to flip that works for your media and then deciding like, Okay, well I need this much more media to get the same amount of yield. And that's where that gets a little frustrating for.

[00:50:28] Guest 2: Oh and once again, thank [00:50:30] you everybody over at AROYA for your continued

[00:50:33] Seth: effort in the market. Absolutely, man. We like talking to you guys. It's fun. It is

[00:50:39] Kaisha: fun. Billbo. Thank you for asking that. Excellent question. Just wanted to return back to the question asked earlier about why does my Terra 12 sos combo read 100% BWC and rockwool?

[00:50:50] Kaisha: I think we, I think they came on live. And if you're on with us, please unmute yourself and let's see if we can get that addressed. [00:51:00] Canna Sutra, og, what's the, Maybe not. All right. Maybe they're thinking about it. In the meantime, Mandy, anything else from our folks over at.

[00:51:13] Mandy: Gido. It's a little quiet over there for now.

[00:51:15] Mandy: I think everyone's just listening to you guys. But yeah, another awesome show. Tons of questions answered. I know I learned a lot, Glasshouse and Greenhouse learning a new term every day with you guys. But yeah, I think I'm good over here on YouTube. So,

[00:51:28] Kaisha: back to you Kaisha. Awesome. Thank you, [00:51:30] Mandy.

[00:51:30] Kaisha: All right, Well, Seth and Jason, any final words before we close up?

[00:51:35] Jason: I don't think so. Pretty close to wrapping up October here. And I think most of the outdoor work in our area is coming to a fast end tomorrow. That's all

[00:51:44] Seth: I was gonna say. If you live in Washington or Oregon or Montana, get your outdoor in now.

[00:51:49] Seth: Today

[00:51:49] Kaisha: crossover needs to be finished by the 21st, huh?

[00:51:52] Seth: It's, Yep. It's freezing soon.

[00:51:55] Kaisha: Yeah. And actually Jason, thank you again for all of your tips. I was looking at my trichomes. I [00:52:00] will be harvesting this weekend. I'm pushing it a little bit but yeah, I'm looking forward to having some beautiful flower to enjoy and I'll share with, Only if it's positive outcome.

[00:52:10] Kaisha: If it's not such a good outcome,

[00:52:11] Seth: I won't say anything. I'm sure it'll be great. You got the climate down there and you did the best thing. You know when you think it's ready, wait another week, it's

[00:52:19] Guest 1: yes,

[00:52:19] Kaisha: exactly. Amazing. All right. Well, Jason, Seth, thank you so much for a great. Another great conversation.
