[00:00:00] Kaisha: Hey, it's Thursday at 4:20 PM Eastern. That means it's time for office hours. AROYA is weekly session for cultivators to hear from the experts and talk to each other about what they're seeing with their grows. I'm your co Kaisha Mandy. It's our last episode of 2022. Can you believe it?

[00:00:19] Mandy: Oh my gosh. Episode 49, the last of the year.

[00:00:23] Mandy: Oh my gosh. What a crazy year it was. Yeah, no, we're also going live over on YouTube shortly. [00:00:30] So yeah, whether you're here live with us or you're over there, make sure you send us your questions. Also if you're active on social media, be sure you're following us on all of the platforms. So that's Instagram, TikTok, YouTube, and now Social Club.

[00:00:45] Mandy: But we have a ton of questions from the last few weeks from you guys, so I'm gonna go ahead and throw it back over to

[00:00:50] Kaisha: Kaisha. Awesome, Mandy, thank you so much. And just a reminder, those of us who are live with us, if you have a question, we're gonna tackle your questions first. So feel free to type those in the chat at any [00:01:00] time.

[00:01:00] Kaisha: And if your question gets picked, we'll either have you unmute yourself or can ask for you. Jason, how you doing? Looking like you're in the holiday spirit over

[00:01:08] Mandy: there. Thanks. Yeah, I'm doing my best. We got some wonderful decorations thanks to Mandy, and just happy happy we're closing out the good the year on a good note.

[00:01:18] Mandy: For real.

[00:01:18] Kaisha: Yeah. The sweater is dope. Mandy, love that reef. W r e f in the background. We are in the holiday spirit over there and let's get started. Ready to kick off our first question. Let's get it going. All [00:01:30] right. Cold in. The d wrote in with a question here. They wrote, I have AROYA and I've recently integrated with metrc. How do I create a harvest batch? Maybe give us a little overview on that.

[00:01:41] Jason: Sure. And as usual, I'm better with the visuals. Let me just jump in and see if I can't share my screen and get you to ride along with us.

[00:01:58] Jason: All right.[00:02:00]

[00:02:02] Jason: So it starts off kind of similar to how you would be using it if you weren't metrc integrated. But a few things that you will want to start to do before you even actually build the Harvest Group. First off is we need to know what AROYA or what metrc tags that you have. And so you can import those into AROYA.

[00:02:22] Jason: We have two options to do that. You can do it with a CSV export from metrc. It's pretty easy. You just go up in the menu items there and [00:02:30] download your available tags list. In this case, we're gonna say add new, so in this remaining unused tags section right there, or we're gonna say add new. And we can either put the first serial number of the roll right there and.

[00:02:47] Jason: Tell us how many's on the roll. Or you can also just use a file upload. And this is that CSV that I was talking about from metrcs. So do that first and that'll make sure that we know what tags you've been shipped and you can [00:03:00] use to attribute your plants and packages. Right here it looks like we've got 200 unused tags, which is great.

[00:03:06] Jason: That number should always be the same number that you have of unused tags available at the facility. And we'll jump in and make the harvest group. So in this case, we will go to our production tab. Just like any harvest group, we're gonna say create new group. In this case, it's gonna have any of the unsaved or incomplete unfinished harvest groups.

[00:03:29] Jason: There you go. [00:03:30] And you can either resume those or you can start with a brand new. For this administration, we'll start a brand new group. We're gonna get it started today. And the grow recipe is just like any other AROYA recipe where it's outlining the different phases and the different parameters, target ranges, tasking, any of that type stuff, light light schedules, and in the future here, irrigations for the different phases and stages of the plant life.[00:04:00]

[00:04:01] Jason: So let's actually use just a example that has prop, veg and flour and dry in it. If you use one recipe that's just for flour, it's gonna ask you only for the flower room, and it's gonna have you select existing clones to add to that group. In this case, we're gonna start fresh and pretend like we're building it from from moms.

[00:04:25] Jason: And so our propagation, let's go to prop [00:04:30] veg flower. We can go to, we go to Flower three for good luck, and then our dry room will go to dry one. And we're starting this Harvest Group today. Let's say we're gonna go take some cuttings and we need to make sure this is registered in compliance. I'm gonna say add plants.

[00:04:50] Jason: And on the left side here, this is, you know, one of the most important pages. This is where we're selecting the mothers that we're taking the cuttings from. A couple ways that you can select those mothers. My [00:05:00] favorite AROYA is just by scanning the mom tag, and you can use RFID scanner or you can use a barcode scanner.

[00:05:07] Jason: Another way would be to type in the last four or six digits and just verify that matches the rest of 'em. So in this case, I'm gonna type in 8 3 0 6. Well, let's use the one that's on top 8 3 0 4. If you don't type anything in, you can also just use this selection [00:05:30] and look through the list of which mothers are available.

[00:05:33] Jason: So if you know the mother, let's make some. Ice cream. Sure bet. And this case we'll use our 18 2 50. And then let's say we make 50 clones from that mom. And we wanna use this tag, or excuse me, this is the tag that we're gonna use for the clone lot. Again, you can scan it, you can also use the last digits of it.

[00:05:56] Jason: So if we use 6 75 for this lot can [00:06:00] select that 6 75 and let's make 50 of those. And while we're at it, maybe we need, you know, 200 of these ice cream sherbets and we'll select the next mom that we're taking a cut from. Obviously we're gonna type in the number that we are assigning for the clone lot and 50.[00:06:30]

[00:06:38] Jason: Great. Now I know I've got 200 clots 200 clone cuts that are gonna be registered into the system and we can go to the next step. Plan rooms. So you can see basics was the last screen that we went through. Add plants is the screen that we're on now. And plan rooms is gonna allow us just to give some more information about where these plants are going.

[00:06:58] Jason: So [00:07:00] propagation, let's just use zone one for all of my plants in this case. And you can do you know, makes Cultivar lots as well. Obviously any time that you're monocropping and things are gonna be a little bit easier to steer. But if you had multiple strains in multiple zones, you can select which zones those strains are going into.

[00:07:21] Jason: Looks like zone one's already used. Let's see if we can use zone four. Yeah. [00:07:30] And this is a demo system, so there might be a few things here that aren't real happy. We always really recommend that people do use the zone features in AROYA because that's what's gonna help attribute your substrate data to the specific cultivars that you have.

[00:07:47] Jason: And that way you could build a more detailed record. Sure. If we had a bunch of substrate sensors in a room and we were getting information, we could attribute that all as an average. But if you detail it in here, then you can start to [00:08:00] actually track the different performance of areas in the room and or different performance of the plants in the room.

[00:08:17] Jason: And it's gonna say, all set up great. So we can see the harvest group name, we can see how many plants that we're starting into clone lots. And then we'll see the workflow of this plant lifecycle. [00:08:30] So we're gonna be in clone for 14 days, veg for 14 early flower, and we're gonna hit some vegetative steering and then some ripening generative.

[00:08:38] Jason: And finish off with that dry cycle for a total of six phases, 105 days. Plan to finish date on 3 30, 23. We'll say finish.

[00:08:55] Jason: Up in the top right, we can see save succeeded. Now we can start to look [00:09:00] at what this harvest Group is gonna be like, and we can also check into production and just verify everything looks good. Cool. Ice cream sherbet, no action items right now. When we do begin to break those out, we'll have other options like advance to veg tag plants, and then towards the end of harvest, we'll have harvest plants.

[00:09:23] Jason: And so tag plants is going to be [00:09:30] Making individual serial numbers from your clone lots. You can select your clone lots. This is a different harvest group that I have. Very similar process. We're gonna say, Hey, let's use the starting id, how many of these plants are we actually turning into viable flower plants?

[00:09:48] Jason: And then we can say, create sequence recorded on the right. And that's gonna start building out individual tags as you put them on the plants. It's always best usually to use sequential tags if you [00:10:00] can. If you can't, obviously you can do a quick audit with barcode scanner, R F I D scanner.

[00:10:09] Jason: And then when you get towards the end of flour, obviously you're gonna have harsh plants. This is where you can enter your plant weights. We've got two options. You can obviously scan plants or whe plants individually. Traditionally some markets require you to have a weight per plant. In this case, definitely best to use your RFID scanner and compatible, preferably [00:10:30] AROYA scale scan, the plant tag with your RFI D scanner, weigh the plant, and when it stabilizes, it's gonna automatically push.

[00:10:37] Jason: So we call this our touch touchless harvesting system, simply because you don't ever actually need to touch the computer until you're done harvesting, and you'll wanna review and finish. In this case, you just scan the plant, it'll select the tag. When you. Throw it on the scale and it'll push through all of this without touching the computer.

[00:10:58] Jason: So that is [00:11:00] the quick and dirty on how to build a harvest group how to transfer your harvest group into different rooms and into different stages. And then finally harvesting that group of plants as well.

[00:11:13] Kaisha: Amazing. Jason, thank you so much for that. Do you mind just reminding our visitors where metrc integration is currently available through AROYA?

[00:11:22] Jason: Yes, it is available in California, Michigan Massachusetts, [00:11:30] Nevada. I think we got Arizona. Colorado. I'd have to look at, get the list in front of me for the, any of the rest of 'em. But I know that's where we're at.

[00:11:42] Kaisha: Awesome. Yeah. Perfect. Thank you so much. Yeah, we're gonna keep this moving. I, we think we got some YouTube questions, right, Mandy?

[00:11:49] Mandy: Yeah. You know we did. So yeah, we got a couple questions in Iron Armor in, we just recently switched from, switched our VE to l e d from C M [00:12:00] H. I'm still having a little trouble adjusting to the l e d learning curve. What are some changes I can make and things I should be watching out for?

[00:12:08] Jason: great question. One of my favorites is to always work with people when they're upgrading to LEDs. So, you know, one of the very first things to think about as well is you know, how much light intensity is those LEDs versus the H p or the C M H ceramic metal highlight in this case and what that's gonna do to [00:12:30] your plants and your environmental factors.

[00:12:32] Jason: I know we did do an episode at some point in time that goes, covers this very well, but we'll go just jump into the basics for for a quick brief on it. So yeah, look at light intensity. Definitely get an idea of the age fact differences that are happening any traditional , H ps or C M H lights gonna create a lot more heat than an l e D will.

[00:12:57] Jason: And so hopefully you can [00:13:00] make some adjustments to your HVAC systems. You know, if you're completely indoor, then you can save a lot of power on cooling in there. And that kind of moves right into the next idea. And that is that traditionally and ideally, it would be awesome to have a spectrum comparison from the manufacturer of your CMH versus your LEDs.

[00:13:20] Jason: A lot of times when people are moving from hps as a great example the spectrum's gonna be different. We're gonna see a lower [00:13:30] radiation to room temperature ratio when we move to LEDs. The simply what this means is that far red light, more infrared light that's traditionally produced by hps is actually keyed up the leaf surface as radiation.

[00:13:44] Jason: And so, you know, depending on how far off that C M H. What the spectrum is it's going to mean how much you want to change your actual air temperatures in the room. What we're shooting for is, you know, a really nice V P D. [00:14:00] So in a veg room, typically we're looking at, you know, anywhere early veg, say 0.7 to up to one towards the end of veg, and which, you know, if you do have leaf surface temperatures, you can also kinda use that to evaluate how much you want to go up in temperature.

[00:14:15] Jason: Usually when we're moving from like a H P S to a modern l e d, we'll wanna up the room temp, you know, four degrees or so. Bedrooms usually like to be pretty warm and pretty humid, right? We're trying to kind of mimic its jungle environment to get these [00:14:30] plants well rooted, get their infrastructure growing and enable their They're eating habits, they're growing habits to be as fast as possible.

[00:14:39] Jason: And so those are kind of the top three items to, to think about when you change it. Obviously, if you've got an AROYA system and you're looking at root zone, definitely get an idea of what those transpiration rates are in the plants. If you're starting to eat a lot faster than make sure that you're keeping up with the nutrient and water [00:15:00] capacities that plant can take.

[00:15:02] Jason: A lot of times, you know, when you do move to LEDs, they might need a little higher ec, a little bit more feed in there as well. Typically, you can cut off a pretty good portion of your veg times if you have improved both environmental factors. When you go. LEDs versus more traditional type of lamp.

[00:15:24] Mandy: Awesome. Yeah, it's been a while since we've talked about lighting but that was a really good rundown. Iron [00:15:30] Armer, you'll have to let me know if we have any other follow-ups with that. But moving on down our list, 5 0 5 Colt wrote in pros and cons of Coco versus rock wool when crop steering,

[00:15:42] Jason: The age old question, coco or rock wool. Yeah, there's obviously they're both probably the most popular hydroponic medias right now and for very good reason advantages of coco let it a [00:16:00] slightly more forgiving, so it has a higher cation exchange capacity, meaning that it's less susceptible to fast changes or dynamics in root zone ec just because the molecules are hanging onto the nutrients a little bit differently.

[00:16:14] Jason: It has more of a, an elbow in its matric potential curve, meaning that it, and that's why it's a slightly more forgiving in most cases, is our plants are gonna start to feel stress before there's actually no water availability [00:16:30] in the substrate. When we look at something like rock wool it's matrix potential curve is very linear, and so we can go to almost 0% water content before we're actually have seen irrigation stress in the plant.

[00:16:44] Jason: So when we think about matric potential, I always like to think about. If I put a straw into a sponge or a substrate, how much vacuum would I have to apply to that straw to get water out of the substrate? And that's just like roots, right? So how much vacuum does a [00:17:00] plant's roots have to apply to get the water from the substrate into the cells of the plant?

[00:17:07] Jason: And so for rock wool, It's pretty easy for that plant to dry that thing almost completely out before it has a lot of cellular stress. And with coco, a lot of times, you know, it's gonna have an elbow, meaning that we might actually visually see stress response in the plant before it it gets to an irrecoverable damage point.

[00:17:29] Jason: [00:17:30] So that's one of the reasons that when we suggest people start using rock wool is after they have all of their environmental and irrigation parameters dialed in simply because, you know, you're much less likely to recover from an incident with rock wool than you are with goco. I, you know, I always like to think about it as like, you know, a Lamborghini versus a Jeep.

[00:17:53] Jason: They're both gonna get us there. Depends what the road looks like if we want to choose the best the [00:18:00] best product for the trip. And then, you know, there's also other environmental factors. When we compare coco and rock wool, it's one that usually. People will tell you the information that supports the product that they like to use.

[00:18:15] Jason: So obviously rock wool is a little bit more difficult to recycle. We don't have nearly as many people that are throwing it out in their compost piles. It's something that should be disposed of or provided back to the manufacturer for recycling. [00:18:30] Most of the large scale rock wool companies do provide a recycling program to, to help recover some of the environmental impacts of that.

[00:18:40] Jason: That being said, obviously that's gonna include chipping and other types of energy use and environmental impacts with Coco. , it's very it's very easy to get rid of. I mean, it's a fantastic product. I use it in my garden very commonly. I use it for [00:19:00] replanting house pots. It's something that you can build awesome super soil with with recycled coco.

[00:19:07] Jason: So if you are a facility that has outdoor options, definitely think about recovering some of those indoor coco pots for future planting uses. On the negative side, you know, obviously there is a lot of shipping involved. Most of the coco's coming from areas like Indonesia and Sri Lanka. And so.

[00:19:29] Jason: [00:19:30] It's really kind of take your pick on the environmental factors. I personally you know, I like the fact that coco seems like a more natural, digestible product for me to dispose of. That being said, obviously rock wool is a natural product. It's blown basal. What they do is they super heat basalt rock and they blow it like cotton candy.

[00:19:54] Jason: It's just, it's does have some items impregnated into it and obviously the [00:20:00] structure of it makes it a little bit less digestible on the huge scale. . So there's some considerations. Interesting. Very interesting. Do you guys want to drop your favorite substrate in the chats? I'd love to know . And then one more kind of logistically I was thinking about I know we've talked about this in past episodes as well, is just storage.

[00:20:23] Jason: You know, Coco, usually you can get as compressed block and so it is a little bit easier to store large [00:20:30] quantities of that, whereas rock wool is going to be in a in a much bigger type of shape. Usually you're gonna get pallets that it's at full size. When it gets shipped, then it is slightly more susceptible to damage.

[00:20:43] Jason: You know, if we drop or kick our pallet of coco, it's not gonna impact the usage of that coco. Whereas if we disturb the fiber in our rock wall, it can have a negative impact on [00:21:00] how effective it is to grow. , that's super important. That would just like be the worst to be shipping it and then ruin it before you even got to plant.

[00:21:11] Mandy: Awesome. We did have another question that came through. Kevin Perez wants to know, what would your recommendation, I'm gonna start over. What would your recommendation be for raising pH runoff from five, 5.5, sorry. Got another question. 5.5 to [00:21:30] 6.2 pH. I raised my light intensity, but soon after my runoff went, but soon after my runoff pH continued to go down and they did come back with some contacts, inputs 2.8, EC 6.2 pH and then 1.0 to 1.3 D. let me know if that makes sense.

[00:21:52] Jason: Yeah it does for the most part. And it sounds like you're definitely in, in flour based on those EC [00:22:00] and VPD numbers. Usually when we see nutrient, or excuse me pH drift, it's related to nutrient imbalances in that in that plant sometimes.

[00:22:11] Jason: Yeah. You know, like in coco we'll see it just natively rise due to the coco buffering. Some things to consider here is obviously, you know, make sure that you are getting that substrate wet up with the appropriate pH. I actually like to go in a little bit lower than my typical feed pH if I can, for rock wool simply because there's a [00:22:30] wedding agent in there.

[00:22:31] Jason: It's a surfactant that allows the rock wool to wet. Perfectly the first time and it's when we, that's why we talk about avoiding dry downs beyond, say 35% in rock wool is after that wedding agent has been pushed through it, then it doesn't necessarily have the ability to soak back up like it does from the manufacturer for original wet up.

[00:22:54] Jason: And those surfactants are usually a little bit more basic. So I'll go in it, it's a slightly less say [00:23:00] 0.2, 0.3 for my initial soak up just to try and, you know, wash any of those surfactants out and make sure it's balanced. That being said, you know, if you do a good job over soaking, say after you slit the bags, you'd run a couple irrigation cycles through, you may not need to have that pH drop.

[00:23:16] Jason: So it just depends on what your irrigation system looks like on what is the easiest for you to do. Getting back to the question, sorry, I got kind of sidetracked there. Check out your leaf tissue analysis. That's gonna give you an idea of what the [00:23:30] plants are eating. And why that pH imbalance is coming into your runoff.

[00:23:35] Jason: Sometimes, you know, if you're going from a five, six to a 6.2, you're probably just right at the edge of being concerned on how it can affect your plant growth. You know, usually we'll see some amount of drift in pH and then that's inevitable in anything but an absolutely perfect system.

[00:23:53] Jason: It's gonna become, really come down to what what nutrients you're using and what strains that you're [00:24:00] growing on, how they eat the different elements and the nutrients. So the best thing you can do there is get a leaf tissue analysis and just check in on if that plant specifically is preferring cations or anions.

[00:24:18] Mandy: Awesome. Thanks for that, Jason. So yeah, we had a bunch of questions come in in that time also iron Armor wants to know when going from an L e D [00:24:30] bedroom to an H P S flower room, should I be matching the DLI from veg to flower, or should I be roughly matching the P F D because of the change in spectrum?

[00:24:40] Jason: I would go with dli. Absolutely. And then, you know, at this point. Most of our l e d manufacturers make pretty good LEDs for both vag and for flower. I know some of 'em out there have even selectable spectrums so that you can help the plant use light at the [00:25:00] right ratios during the times in other industries, and we're seeing it pretty commonly with most cannabis plants right now, is that more, more blue light does help early plants develop roots stems, stocks, the infrastructure, you know, the vegetative type of growth that we're trying to hit as hard as possible during veg.

[00:25:20] Jason: And then a lot of times when we get towards the end of ripening just like, natural mimicry, The little bit farther red helps the plant develop its terpene [00:25:30] profiles, finish off and ripen the buds as well. So you've probably gone a great track using LEDs and Vegs gonna help you cut that veg time using hpss cuz it's what you have in Flower.

[00:25:41] Jason: Definitely a good route to go. I would use dli. . And that's simply because, you know, when we are hitting those different chlorophyl A and chlorophyl B, it's really gonna be the sum of photons that's hitting the plant. And so when we drop our light cycle from 18 six [00:26:00] to a 12, 12 cycle, obviously we have about what third, you know, 33 less 33% less time under the lights.

[00:26:07] Jason: And we wanna make sure that plant is keeping up with the growth rate that has come out of veg at which means we need to get it the same amount of energy. You know, when we look at the basic process of photosynthesis, it's CO2 plus water catalyzed by light turns us into digestible sugars that the plant makes its biomass from.

[00:26:26] Jason: And so you definitely wanna make sure that you're not dropping out [00:26:30] light at a point in time where you can definitely Make time, make plant with with what's coming into it. You know, as far as how much people want to ramp up after they've gone into flour. I've seen a lot of different tactics here.

[00:26:46] Jason: You have a lot of people that, you know, say that, Hey, we need to, you know, baby these plants going into flour. Can plant is a very light hungry type of plant. So usually I only try to step the lights up maybe once or twice. [00:27:00] So as I'm coming out of veg, I'll match the DLI in my flour, which means that my ppf D needs to be about 33% higher the first day of flour.

[00:27:10] Jason: And then I'll usually try and step up to full intensity in, you know, five to 10 days, depending on how big that step is based on my.

[00:27:20] Mandy: Awesome. Thanks. So yeah, we have a ton of questions over on YouTube. Dan wrote in and wants to know, hi, could you discuss [00:27:30] ways to minimize plant touches? I've been growing in rock wool with drip irrigation for a few runs now, and my leaves are growing so fast and big that I have to defoliate every week.

[00:27:40] Jason: Oh, the good problems. Yeah. Ways to reduce plant touching. Well, Nick obviously depends on some of the practices that you're doing now. Using the right substrate sizes is one way to do it. So making sure that we're not doing something like a four by four block on a six by six block, or making [00:28:00] sure that we're vegging in the right size substrate and we're going into flour on top of the right size substrate.

[00:28:06] Jason: Some of the ways that you can help. By, you know, help to not have too much foliages using some of the crop steering techniques that we talk about. So making sure that we're not pushing the plant overly vegetative, and that's just gonna help encourage node spacing encourage that the plant hits the plant height that we want to at the right time to do that.

[00:28:29] Jason: And [00:28:30] then obviously get an idea of, you know, what your light penetration is. Anytime that we are at a good light penetration, we're gonna be able to control some of that node spacing with our irrigation. You know, if we're doing too low a light than, a lot of times we'll have plants that stretch much more than we want and, or make more leaves, then we're desiring that plant is trained to harvest as much light as it can.

[00:28:53] Jason: And So making sure that your environmental factors are right is one way to do [00:29:00] it. And then some of it kind of comes down to what's the cost of the labor work versus, you know, what's, what do you gain by reducing some of that lower stems? I have worked with clients that do see of green type of application where they're very heavy on the de leafing and they're trying to get as much eight buds as possible.

[00:29:20] Jason: And while that's great every input is a cost. And so if we can use techniques to reduce our labor, make sure that all of our nutrients and [00:29:30] energy are turning into some type of sellable product, maybe it's worth it in the end to possibly, you know, do a quick machine trimming to, to get the lar few stuff off that.

[00:29:40] Jason: And then allow our trim teams to, to process the A buds sell out the larf to, you know, either a nickel fritz brand or a, you know, a schwag product. And then make the most of it. And so it really kind of comes down to what some of your distribution looks like and some of your labor staff. You [00:30:00] know, how much does labor cost, where you're at?

[00:30:02] Jason: How effective are your teams? Obviously making sure that you are debriefing the right parts of the plant are some of the ways that can help. awesome. And make it easy. Yeah, make it easy for your people to work. And I guess that's not specifically related to how you reduce the plant touching, but you can reduce the time that plant touching takes by, you know, making sure that your benches are rolling well, that your aisles aren't so [00:30:30] tight, that people can't walk past each other, to get rid of the waste product.

[00:30:34] Jason: You know, if labor is one of your concerns, make sure the facility is as ergonomic as possible so that your team can work effectively.

[00:30:43] Mandy: That is a great note. Ergonomics can add to efficiency. That was my last job. Enough about office chairs. So yeah, we have some more questions over on YouTube. Jason wrote in Aha. Hi, another Jason. They're from South Africa. I found fusarium in [00:31:00] some trees. How do I deal with it preventatively for the next run.

[00:31:04] Jason: Fu fusarium. So, you know, some of the rot that's usually related to some root issues. A couple things that you can make sure that you're using as sterilized media. Obviously rock wool and coco these days are on the top of it. They've got very low organic matter. Both of them are sterilized, usually for most all manufacturers when you get them making sure that you're [00:31:30] using clean tools so that you have sanitized cloning practices that these diseases aren't transferring from mother to clone.

[00:31:39] Jason: And kinda on that same route, you know, if you are still using hard pots, you're gonna have to clean them. Probably one of the, my least favorite jobs in a facility is cleaning out hard pots. And so I always encourage people to move away from them if they have the opportunity to do so and move into coco bags [00:32:00] or rock wool slabs.

[00:32:02] Jason: Another thing that you can do is also making sure that you're creating a healthy aerobic root zone. So in any time that we see in black roots that aren't just beautifully white, a lot of times that's related to a lack of oxygen in the substrate. And there's really the two easiest ways to make sure that you are getting the right oxygen in the substrate is by using low flow drip emitters so that we are irrigating in smaller pulses.

[00:32:28] Jason: It's allowing for the block deck, [00:32:30] like a vacuum. Pretend we irrigate, it's gonna pull fresh oxygen in behind that irrigation. And then another thing is making sure that your irrigation has as high a dissolved oxygen as you can to support the healthy root zone. And, you know, there's a number of ways people do that, you know, nano bubblers and air stones in their irrigation tanks.

[00:32:52] Jason: Really the easiest is making sure that the air tip or the water temperature of your irrigation lines isn't too warm and isn't too cold. [00:33:00] That way we can, one, keep the dissolved oxygen as high as possible. Ratio of dissolved oxygen. This solubility of any gas in a liquid decreases as the temperature of the liquid goes up.

[00:33:12] Jason: And so, you know, if we're keeping it, you know, I'm saying that 67 degrees range, that's usually gonna be about right for not shocking the roots and maintaining a higher dissolved oxygen.

[00:33:25] Mandy: We love a healthy root zone. Awesome. Yeah, that's it for the [00:33:30] questions over on YouTube for now. So I'm gonna pass it back over to you, Kaisha.

[00:33:34] Kaisha: Amazing. Thank you so much Mandy. And one of my favorite things about all of these platforms that we're on, there's a lot of resource sharing happening on YouTube, so we love that. Love seeing the conversations going. diyan posted a comment here, too much nitrogen can cause you to defoliate that often also as pertaining to that earlier question. So thank you for that diyan. And then also our teammate Rachel. Shout out to Rachel. Good to see you. Clarified the states that AROYA work [00:34:00] AROYA is, metrc integration is currently available.

[00:34:02] Kaisha: So I wanted to clarify for everybody that's in California, Colorado, Massachusetts, Maryland, Maine, Michigan, Montana, Nevada, and Oklahoma. Woo. All right. Thank you Rachel. Yes. Takes a village. Y'all. Alright. Moving on to the next write-in question here. This one came in from turp daddy. They wrote in does giving multiple irrigation signals to the plant in veg versus giving huge dry backs and then completely saturating the pot, [00:34:30] increase or decrease metabolism in the plant.

[00:34:34] Jason: Yeah. So always gonna start off here by talking about a balance. And in veg usually we're gonna shoot for a little bit smaller dry backs. Yes. Irrigation events do trigger plant growth. And so in general, we'll want to have a little bit wider irrigation window. We'll wanna do multiple shots. You know, say if the plant can take it, you [00:35:00] know, six to eight might be an decent place to start in veg, and that's just gonna depend on how old the plant is and how big of the substrate that you are using.

[00:35:08] Jason: But yeah you know, it is a balance. We do want that plant to build biomass as fast as possible, stem stocks and other things so that we can flip it a little bit. I know it's a little bit vague, but, you know, we've got so many factors in there as far as is the environment right? Is our substrate size appropriate for the size of plant that we're going?

[00:35:29] Jason: Are we [00:35:30] vegging too long? And we need to get those plants into a flowering stage and start to push 'em more generatively and decrease that irrigation window and decrease the number of shots. But typically yes, you're right. We'll wanna have more smaller shots when we're trying to steer vegetatively.

[00:35:47] Jason: And that does include during the veg phases as well. The early badge 18 six light cycle.

[00:35:56] Kaisha: Beautiful. Thank you Jason. diyan, I see your comment here. Low light [00:36:00] level also will, it is gonna turn out too much leaf, so that's another drop in some more knowledge here. Love that. All right, Andy, I know we got more live questions from YouTube. Sending it over to you.

[00:36:09] Mandy: Oh yeah, it's popping over there. So Ismail wrote in, where can I find a feeding schedule for irrigation, times for both veg and flour? Automation is new to me and I've been following for a while now, and I've just begun getting more and more into it. I'm hearing different things everywhere I look. Love y'all. Thanks.

[00:36:29] Jason: Well, [00:36:30] I'll go out there and just tell you where I like to see some of the information and somewhat does disagree that probably the absolute best starter irrigation schedules come right from groan. Surprisingly enough, that's your substrate manufacturer and they have some pretty nice white papers on how to get stuff growing.

[00:36:52] Jason: I also like the floor flex tech support. Instagram. They do a fairly good job walking through the introduc introductory [00:37:00] steps to P one and P two irrigations and how that can affect plant growth and give you kind of an idea on. How to make the calculations. You know, we do, if you're a AROYA customer, we've got we've got our cultivation quickstar guide, which probably should have been my first answer.

[00:37:17] Jason: But that's okay. And then, you know, I think there's some other companies out there if maybe we've seen Front Row Athena, some of those guys are starting to produce some materials in there to help everyone utilize their products. There's a ton [00:37:30] of information out there really. If you just Google search crop steering or irrigation strategies, cannabis you're gonna get it.

[00:37:38] Jason: And really the best thing that you can do is read from multiple sources before you begin. That's because there is no exact right strategy. So when we start with how we want to get it done, we have to kind of tick accumulation of how are all these other companies recommending this to, to work, and how does that fit my [00:38:00] specific application?

[00:38:01] Jason: You know, are my light levels gonna keep up with transpiration rates that are described in the white paper that talks about what their transpiration rates are, right? Some of this stuff is based on an outdoor where we might have extremely high P F D. Some of it might be used in a different substrate size or substrate type.

[00:38:18] Jason: Some of it might not be at the nutrient levels that, that you need to be at. So, you know, the best thing you can do is use your tools to build the knowledge that you're at and [00:38:30] then reassess using those tools and see did I make an improvement? Have I decreased it? How many things did I change?

[00:38:37] Jason: Which one of them made the difference. And so I usually try to help people not get too excited about making all the right choices at once, if you will. Before you begin, try and get the best solution that you know how. And obviously since you're asking questions here, use our resources as well.

[00:38:58] Jason: Watch office hours for [00:39:00] as many hours as you'd like. I'm sure that there's a ton of things in here that can help anyone get started on the right irrigation schedule. Early in the show, I, we probably did 10 or 15 episodes, specifically dedicated to crop steering and talking about P one s and P two s and how you can evaluate how many shots, the right sizes, shots, and the timing of those shots for your application.

[00:39:25] Mandy: Awesome. Thanks Jason. We got a couple more questions over on YouTube. [00:39:30] Iron Armor wants to know, as for climate, from transitioning from l e d veg to h p s flower, should I be adjusting the flower room's temperature and relative humidity to match the leaf's surface temperature and rooms V P d to what it was in veg?

[00:39:47] Jason: It's probably not a bad route to go. I would definitely, probably be a little bit cooler as just a starting baseline. And that's simply because that plant's gonna [00:40:00] feel slightly hotter environment, even if our temperature is been dropped in that h p s. So that's that radiation room temperature ratio that we'll talk about some more advanced agronomic books do talk about this as well.

[00:40:15] Jason: It's nothing that's new and specific in. Agriculture. It's just that a lot of times for indoor growers, it's not something that we have thought of for cannabis. So definitely make sure that you are [00:40:30] taking that route. You might not need to drop it all the way to match perfectly. But that would be the starting point I would go for.

[00:40:40] Mandy: Awesome. Thanks for that advice. Diyan has a couple of questions about boron. So what's a good boron level for my tissue analysis? And second question is for how how much boron should we aim for in stretch? You know, I can't [00:41:00] give you exact numbers for the boron concentration on that.

[00:41:05] Jason: Best thing that you can do is document what those boron levels differentiate between different runs and which runs match the plant morphology that you want.

[00:41:18] Mandy: awesome, diyan. Yeah, you'll have to let us know if you find any resources out there. But yeah, let us know. That's it for YouTube right now. So Kaisha, I'm gonna pass it back over to you.

[00:41:28] Kaisha: Thank you, [00:41:30] Mandy. All right. The questions are coming fast and furious, and just a reminder to those who are on Hangouts, now's your chance. We got 20 minutes left in the final episode of 2022. 22. So drop your questions in the chat. Let's get 'em answered. All right. I'm gonna ask this one. Northern grown TURs asked, what does a proper flesh look like? That seemed like a fun one to talk about in the last episode of the year.

[00:41:52] Kaisha: Thoughts on,

[00:41:53] Jason: yeah. So a proper flush doesn't use the term [00:42:00] flush because I think there's just so much different usage. Or application of what people mean when they say flush. I'd like to call it ripening. For some people, what I say is ripening is exactly what they're doing for flush. The thing that I like to use ripening is because I'm talking about the goal in the plant, and there are many strategies to get to that goal.

[00:42:23] Jason: And a lot of it actually has to do with getting the plant to the right [00:42:30] age, using the right environment at those points and not specifically what you do exactly when you get to the ripening stage. For me, yeah I'm gonna like to keep that vpd up. It's say 1.4 just to help me avoid any molds, mildew, titis towards towards the end of the cycle when I'm most liable to, to get that.

[00:42:50] Jason: Obviously when I've got huge coals and stuff, it's it's a time where we need to keep it a little bit drier just to optimize our chances of [00:43:00] having a fully harvestable crop. . . And the reason I don't like flush is because a lot of people historically have gone to no nutrient content in their in their irrigation when they say that.

[00:43:13] Jason: And so that's usually definitely not what you want to do. That big of change is gonna starve your plants out. It can build necro, necrotic sites in those big colas and encourage. Some of the pests and molds and [00:43:30] mildews to be attracted towards the bud. You know, another thing about going to no nutrients is it's such a quick change to the plant that you're not gonna see positive results.

[00:43:41] Jason: So usually I like to, you know, kind of taper it down towards the end of the cycle. And depending on how long the cycle is, it might be anywhere from, say, five days to 10 or 12 days. A lot of times we'll talk about half or three quarters nutrient levels. [00:44:00] We've seen some people that actually adjust their nutrient balances and really try and taper out, make sure that there's no nitrogen in the irrigation towards the end.

[00:44:10] Jason: But we do wanna make sure that plant has.

[00:44:14] Kaisha: That's a perfect segue into this next question here, which was submitted by French Flair. They wrote in what is the impact on the nutrients, on the yield, and they wrote cannabis nutrients versus agriculture.

[00:44:27] Jason: Well, if I mean, [00:44:30] if I hear that right, cannabis nutrients are just a specific woo specific blend of nutrients and most big agriculture, they just have their nutrients blended, custom for specific different plant types for different specific application methods.

[00:44:52] Jason: And cannabis. A lot of the companies, they're just getting a custom blend that they know works well for cannabis and [00:45:00] specific. So it's not like there's really anything different in the actual elements. And to the molecules, it's just comes down to the blend rates and the concentrations of those molecules.

[00:45:12] Jason: And simply because, you know, I'm not a nutrient scientist. I like to usually just tell people the brands that we see customers be successful with, and . And if they have an agricultural scientist that you know, does nutrients and chemistry, then you know, [00:45:30] feel free to source, source your elements and make, do your own blending.

[00:45:34] Jason: That's what the nutrient companies do for the people that buy the chemicals from them.

[00:45:40] Kaisha: Awesome, Jason. Killing it as usual. Thank you so much. All right, Mandy, we got YouTube.

[00:45:45] Mandy: Oh yeah. You know, we do. Craig wants to know when daily dry backs in generative steering exceed the medium's ability to stay above an extreme low volumetrc water content. So 35 to 40% in rock wool [00:46:00] are less larger shot size or more smaller to bring wa volumetrc water content up enough to not have to P three. Let me know if you wanna hear that again.

[00:46:11] Jason: No I got it. You know, if you are there, then you might be growing too big of plants for the size of substrate that you're in. And so kind of think about that going forward. I know almost anytime that you hear Seth and I talk about solutions to solve problems that comes down to [00:46:30] why are we dealing with this problem rather than what can we do right now to make things better. I would probably go with, you know, more smaller shots just to try and keep that water content up a little up towards the top a little bit higher.

[00:46:44] Jason: Obviously that's gonna be steering your plant less generative. So if you are a generative steering, just keep in mind, hey, my substrate is limiting me on the control I have over this plant's morphology.

[00:46:57] Mandy: Super important stuff to keep in mind. Yeah, you'll have to let [00:47:00] us know if you have any more follow ups. But yeah, I'm gonna kick it back over to you, Kaisha.

[00:47:04] Kaisha: Doing it here. All right folks. We had a few minutes left in the show live. Folks, now's the time. Type in your questions. This came in from drunk Norm Nomad four 20. I love the handles. They wanna know when in vegetative bulk is it important to achieve 30% runoff.

[00:47:22] Jason: I, it's gonna depend on your media a little bit. Like 30, pretty high. That's, those are hungry plants if you're in the right [00:47:30] size substrate. Kind of coming off of our last question, you might, you know, you might have a plant substrate size mix mismatch where you're just pushing it, you know, way too hard.

[00:47:41] Jason: That being said, you know, big dry backs during badge bulking means that plant is utilizing a lot of nutrients in and water as far as percentage goes. Obviously if I'm growing a six foot plant in my little cup here, a 30% dry back would mean [00:48:00] that I still am not getting anywhere near enough water and nutrients to optimize that plant.

[00:48:05] Jason: That's why we talk about optimal substrate sizes, making sure that we can modulate in the appropriate water content ranges and still get the amount of plant that we wanna grow.

[00:48:20] Kaisha: Wonderful. Thank you for that, Jason. All right. We got a good one from Demo Grown here. They wanted to know what's the best way to steer the crops the last few days of flow, say day [00:48:30] 45 through 63, and then they list here vpd in temps. So I don't know if they're looking for some ranges there, but yeah. What are your thoughts? Best way to steer crops the last few days of.

[00:48:40] Jason: Yeah, I mean, kind of goes down to what we were talking about with ripening. I mostly just hit on irrigation there. You know, for environments being in say, 1.4 would be the type of V P D that I try to hit.

[00:48:55] Jason: Obviously at night you can have a little bit lower p d just really try to [00:49:00] avoid vpd swings, especially towards the end. I mean, those are the kinds of things that, that can get you into trouble. And the reason that I do mention that was because of night day temperature differentials.

[00:49:12] Jason: And depending on you know, what kind of strain that you're running and how much purling you need into it that night day differential, usually when it's increased, it'll help the plant produce anthocyanins, and that's what's responsible for the purling color. Cannabis and also in things like blueberries and [00:49:30] huckleberries.

[00:49:30] Jason: And in a lot of markets right now, especially, it is a more desirable product. And so we'll see, you know, 10 degree, maybe a little bit more than that. Night, day differentials. And you wanna make sure that you're modulating your humidity to keep those VPDs nice when you are doing that big of a change.

[00:49:49] Jason: And obviously when we do that, if we can taper it, our systems allow us to taper it rather than, you know, going from, Hey, we're at 75 and now [00:50:00] we're at 65 and maybe we saw, you know, 10 or 15% humidity change. Let's taper those out over an hour or two hours if we can, just to kind of help the environment attribute to it.

[00:50:13] Jason: There's some interesting. Literature on tomatoes, on how actually, you know, doing that at specific times in relationship to lights on, lights off have enabled people to get slightly more biomass on their products. But you know, Intel, [00:50:30] we get a little bit deeper into the science of cannabis.

[00:50:34] Jason: Probably nothing that I'd get too wild about unless you've got a good r and d room and you've read a lot of those tomato papers.

[00:50:45] Kaisha: Always learning never stops. Right. All right, we're gonna keep going here. Drunk nomad rod. Oh wait, sorry, Mandy. Yes, you too. What's going on there?

[00:50:53] Mandy: Yeah, we just said I'll follow up from Craig about his daily dry backs. So he says next round has half the [00:51:00] veg time. Thanks so much. I've been giving fewer shots, so we'll change tomorrow.

[00:51:04] Jason: Cool. Awesome.

[00:51:07] Mandy: Awesome. All right, back to you, Kaisha. Changing lives over here. I love it. Okay. Drunk Nomad Rodin, how often should I water when using Royal Gold Tuper as my substrate? I hadn't heard of that particular substrate before, so I thought that was a cool question. What are your thoughts, Jason?

[00:51:23] Jason: I've grown a lot of cannabis in Royal Gold Tuper and [00:51:30] think that you're gonna need to use some sensors and watch what your water contents are and what your transpiration rates. The dry down in there is as far as the number and the amount of irrigation kind of just comes down to our. Fairly basic P one P two irrigation strategies. Are we trying to build infrastructure so that we have enough plant to produce as much bud as possible, [00:52:00] or are we trying to produce more buds because we've got the infrastructure that we need?

[00:52:09] Kaisha: Sorry, too many windows open. I feel like that's probably a general rule of thumb for any steps straight. No, Jason.

[00:52:15] Jason: Yep. For any substrate. And that's kind of why looking at water content and EC is such a universal tool. Anytime that we have some type of media that we're growing with, [00:52:30] we wanna be making sure that we're staying in the ranges that keep that media effective.

[00:52:37] Kaisha: Wonderful. Thank you so much. All right. Over, back to you Mandy,

[00:52:41] Mandy: man. So many questions today. So diyan has a question. Can I switch from calcium nitrate to calcium sulfate after stretch? Cuz my plants won't need that much nitrogen after stretch.

[00:52:52] Jason: I mean, you can, it, you know, it's something that you might do a little [00:53:00] blend or mixing with and not do any instant change. And best thing that you can do is document, Hey, here's when I did it. Here's how much I changed of it. And without limiting some of those horses of those chemicals as well. And just get an idea of how that affected your plant growth. So give it a shot. I personally haven't, so I can, I can't tell you.

[00:53:24] Mandy: It's all about documenting and living and learning. All right, back over to you, Kaisha.

[00:53:29] Kaisha: Thank you, [00:53:30] Mandy. All right, we gotta write in here from Guatemala. Andre's four 20 wrote in, can't get fully white ashes. I use water to flesh and reach 73 ppm, but not enough. I use general hydroponics because he's in Guatemala. We're not there. So, wanted to get your thoughts. What do you what advice can we share with Andre's four 20?

[00:53:51] Jason: You know, just making sure that you are harvesting at the right time is probably one of the easiest ways to do [00:54:00] it. Obviously some results have shown that making sure that you've decreased the amount of nitrogen in towards the end.

[00:54:07] Jason: Yeah, that the white ash thing is I think a lot of times where people do want to go to straight ro. That's not how we like to solve it because we don't wanna jeopardize the chance of of crop loss due to plant starvation and Nero necrotic sites in the buds. So yeah, I, [00:54:30] I would probably keep feeding it nutrients and maybe just modify that plant uptake with a little bit higher pH or a little bit of an adjustment to your nutrient blend.

[00:54:40] Jason: Obviously if you are just using some general hydro. Pre-mixed nutrients, you may or may not have an easy option to taper out something like nitrogen.

[00:54:55] Kaisha: Awesome. Thank you for that Jason. Good luck on Jays K. Keep us posted, let us know how we can help. [00:55:00] Okay. Fire Station wrote in, when do you start the elevated EC levels prior to stretch? Looking forward some advice there.

[00:55:10] Jason: Yeah, sure. So I mean, prior to stretch, so like if we're coming out of veg I guess that's probably what it's talking about here. Like, you know, running in Periods when we're getting into a new media, most of our system we don't usually recommend people do too many EC [00:55:30] adjustments.

[00:55:30] Jason: We like to use the actual crop steering techniques to modify the ec in the substrate itself. So if we got a bunch bigger dry back than our daily ec in the substrate's gonna be higher. Simply cuz we're not pushing it out with fresh nutrients. We're allowing a little bit of nutrient buildup. And so, you know, when we talk about generative stacking, that's exactly when we're talking about it.

[00:55:54] Jason: And if we're transplanting right at, right when we start flour, [00:56:00] so our plants are going onto a bigger substrate, right at 1212. We'll run through you know, three to five days of Rodin and dry down maybe a little bit more maybe seven days if you need a little bit bigger dry down.

[00:56:14] Jason: And then that's right when we'll go into generative stacking and letting that EC build up in the substrate simply by reducing the time that we're irrigating and reducing some of our runoffs. So, you know, feed ECS are gonna depend on [00:56:30] the nutrients that you're using light sources and environmental factors.

[00:56:36] Jason: And historically we've seen that higher ECS in the plant can have benefits at this point just based on some of the qualities of the nutrients versus what maybe 10 years ago people were doing in their medias. And so, Yeah. And get a system that can tell you what those ECS are over time, because you know, [00:57:00] when we talk about ecs Sure.

[00:57:02] Jason: FDCs pretty easy to capture, right? When we're looking at nutrients and solution they're not gonna change too much unless we change the rate that we're injecting them to. Or we had more in a batch tank, for example. Whereas the nutrients in our substrate is always gonna be dynamic. As our plants are using up water content, we're gonna see some concentration of those nutrients.

[00:57:26] Jason: Us usually go up. If we're already low in nutrients, we actually might [00:57:30] see it go down if the plant is eating nutrients faster than the concentration is increasing due to water content loss. And so having an idea of what those trends look like, One, it gives you exactly knowledge of what the plant is feeling in the substrate, what your EC at the plant is, and then two, how you can best modulate your practices in order to get those ECS where you want them.

[00:57:56] Kaisha: Okay. Thank you for that. Jason. You know, this [00:58:00] episode is really we're talking a lot about substrates, so this is great. Great way to close it out. All right, I have one more question. It's a multi-part. I'm gonna read the whole thing. If you need me to break it down, I'll break it down. All right.

[00:58:12] Kaisha: Here we go. Dave Ray Rodin. I'm trying. Chark Bio Pot compressed coco. Three liter pots next round. Any experience with these? They stay stabilized. pH six to 6.5 and that they're high. C, e, c. What feed [00:58:30] pH should I be aiming for? And then he is just wondering, any other tips going straight from clone into them? Quick few, eat, bed, then flower. Should I be targeting the same dry backs for promix and three gallon pots as I would in coco? I'm able to get 1% dry backs per hour. Currently during the day 2020, day 22 of flour. Side note, my peak moisture I'm able to achieve is 44% low on the day. Lower of the days has been, the nine has been 19%.[00:59:00]

[00:59:00] Kaisha: do I need to rewind a little bit? Break that down.

[00:59:02] Jason: I think I've got most of it. We'll just start off with some of the easy ones. Yeah, charcoal's been a pretty long-term producer of coco, and, you know, for the most part they're pretty well regarded, so not a bad product to use. I don't know that they're the most popular with really high quality growers right now.

[00:59:21] Jason: But they've definitely proven their value in the industry. And you know, pH as far as going [00:59:30] into coco, usually I like to be about 5.8 to 6.0. Maybe get a little bit higher towards the end of the cycle just to, to help the nutrient balance in the plant stay where we want it to be.

[00:59:43] Jason: And so, yeah. Next question for how is that different than something like you know, promix one, you're not filling pots. That's definitely nice you know, I think in application, there [01:00:00] really shouldn't be that many differences. You're definitely gonna see some changes as far as how that water is retained and how the nutrients build or release from the substrate.

[01:00:09] Jason: The best thing you can do is use time series data, use a system like AROYA that gives you an idea on how you can adjust that for growth parameters that are similar to what you're used to.

[01:00:24] Kaisha: Amazing. Thank you, Jason. All right. Normally we will close down the show, but we had a couple more questions and then YouTube. Mandy, can we [01:00:30] take them? Can we get it? Get it in?

[01:00:31] Mandy: Yeah. Yeah. You guys know I can talk fast. Okay. So Craig wants to know, can I assume when runoff first occurs that the heavier elements in solution are more likely to be washed out before the lighter ones having problems keeping calcium levels up and nitrogen down With Cal ca, N oh three I think that you know what that means.

[01:00:53] Jason: I mean, one, one aspect is gonna be, yeah, how [01:01:00] long has that nutrients been into the rock wool? Like how long since it was blended in in solution. So if you are hitting a lot of shots in a short duration, there's a chance that the some of those haven't settled yet and towards the bottom, but I mean, probably gonna be a little bit heavier.

[01:01:21] Jason: Nutrients are going to settle toes the bottom just because of gravity. Not something I've actually specifically really ever looked at or thought of. If [01:01:30] our plants have a well-established root zone, I don't think it's gonna matter. The plants will. Grow roots in the most preferential solution possible.

[01:01:40] Jason: If so, if I had two cups here and the plant was right in the middle with some ruts in both sides, I could modulate the EC of either cup and the plant's going to grow more roots in the one that it prefers. So kind of, kind of a fun experiment. You know, , if you wanna see it in application. So, you [01:02:00] know, as far as h how that actually, you know, affects the roots, probably not a ton.

[01:02:04] Jason: Sure it's gonna affect the nutrient balance and the EC levels if we're on a very low runoff amount. , keeping an eye on your pH is how you're gonna know if this is actually happening or not. And making sure that you have leaf tissue analysis to say, all right, well, I'm seeing this happen even though my plant tissue is showing a healthy balance.

[01:02:26] Jason: And you can use, you know, SAP analysis as well [01:02:30] too. Really just whatever you're used to, using what you have documented and what's most available for you to get those tests done. Awesome. Thanks for that. Oh yeah. We're we're rounding on our hour and we have two more questions. They're both from Kevin over on YouTube, so he wants to know what humidity do you go for when curing the flowers in jars after the 12 to 14 day dry?

[01:02:53] Jason: We'll start with that. Yeah. So, you know, in a 12 to 14 day dry, we're [01:03:00] usually shooting for a water activity specific number. A lot of times we'll talk about 0.58 and it does slightly depend on what your consumers prefer. The reason that we are looking at something like a 0.58 is just to help make sure, you know, by the time it's packaged, it hasn't gained any water content and that you're not losing more quality than you need to by over drying more weight than you need to by Overdrawing.

[01:03:27] Jason: So in, you know, in something like a jar like [01:03:30] that, if I have a 0.58 water activity going into the jar, then I wanna 0.58 water activity during the cure cycle, and that's going to mean that I'm maintaining water balance in there and we're not having any moisture transport between the bud and the environment that it's curing.

[01:03:47] Mandy: Awesome. Sweet and succinct. So Kevin had one final up, final question. Do you recommend stacking EC in late veg a week before flower?

[01:03:57] Jason: In [01:04:00] late veg. I mean, we could I mean, it depends what you're trying to do with your plant heights and how if you've already trans transplanted or not, you know, if you've already transplanted into a new media, then you know, you might want to keep that media stabilized during that timeframe.

[01:04:23] Jason: If we're gonna transplant later on, it might be nice to, you know, start to let your EC [01:04:30] stack up a little bit so that you're ready for the ECS that you're hitting in flower. You know, a lot of nutrient brands are also recommending that people have higher ecs during their veg you know, especially if they are veg and LEDs.

[01:04:44] Jason: So really kind of just depends on what your targets are what your room parameters are in order to. Make the balance. Obviously we don't wanna make changes too fast but if we're looking to alter plant morphology, then that's an option. [01:05:00]

[01:05:01] Mandy: Awesome. Thanks for that. And that will be it for us over on you too. Thank you guys so much for all your questions and shout outs. Kaisha, I'm gonna pass it back to you.

[01:05:09] Kaisha: That's the true thank you to everybody on YouTube. Thank you to everybody on Hangouts today. Anybody who's watching this later on. We really appreciate you. Jason you killed it. Thank you so much for answering all of these questions today.
