Main Cabinet Evolution

Also forgot to post a pic of a couple buds from the last run (‘Purple Haze’). ‘Tall’ plant is on the left, ‘Short’ plant is on the right.

They were both very dense & at a nearly-ideal moisture level, not clogging the grinder. They might need some more time in the jar to reach max potency, but they were both nice & strong. I’m still burping the jars for a minute or two every couple days, but they have gassed off most of the chlorophyll. I like the flavor of the short plant better, but they are both mild in flavor. The short had green coloring & is a little more sweet-tart & citrus. The tall had purple coloring & is more of a lavender & earthy flavor. I smoked a joint of each, & then a combo joint. They’re both good joint-weed, but the short plant might also taste good in glass, whereas the tall plant might not. I should test that later.

Three days since my full res-change, & did a 1-gal partial res-change today.

Plant seems happy with the PPM running between 640 & 660 for now. Plant is drinking around 1/2 gallon a day. pH crashed a little by lights-out yesterday, & lights-on today, running down to around 5.5 from around 6.1 - 6.2 both times. pH adjustment fixed that last night, & the partial res-change fixed it this morning. It ran down from 6.2 to 5.8 today, so I just bumped it up to 6.2 again.

Plant has seemed to have stopped stretching, although it still may grow up a little more over time.

I raised the light again a couple clicks today, trying not to burn the tall top.

I have three main tops around the same height, & that tall one, plus a shorty near the center of the back wall.

I’ve pruned off some more lower bud-sites & some lower main fan leaves, & also have partially trimmed some other main fan leaves.

Hoping to maybe be able to get some of the remaining lower bud sites to finish, since I don’t have a whole lot of tops up top shading everything down below. Unfortunately having to keep raising the fixture for that one tall top might lead to me chopping off more lower stuff.

Spent some time dialing in the controllers again due to moving light & sensors upwards again. Ambient RH has been on the rise over the past day or two, not sure that my humidifier has even run since filling it last.

Here’s a look at the three Thermpros hanging in the center, & in the front right top & lower corner. Leaf temps running around 8 to 10f lower than surrounding air temps.

Thermpro hanging in center: I moved it a little closer to the light itself & into hotter air after raising the light today, so it started reading a little hotter, but the tops were probably in about the same air temp as they were before I moved things. Eventually I dialed down the exhaust fan temp setpoint anyway, & it’s running a little cooler now overall.

Thermpro upper front right corner: It’s running pretty close to the hanging center unit. Idea is to be able to pull the hanging one out of the way after the stretch, & just refer to this one as if it were in the center, since it seems to be running closely to the center one.

Thermpro Lower front right corner: This helps to see what the temp & particularly the RH is doing down low.

Couple days into Week5 since the flip:


She’s been handling the max 675 PPM over the past couple days, I might try to push it up to 700 tomorrow. pH has been better-behaved over the past couple days. Although I did do an early partial res-change yesterday, mostly in order to bump up the PPM since she’s been taking chunks out of the ppm number daily. She’s also been drinking well, a little over a 1/2 gallon over the last 24h. She stretched up another maybe quarter inch over the past couple days & the tallest top seemed to be in too-strong light imo, so I raised the light a couple more clicks today. The leaves started stretching upwards by the end of the day, but I don’t think that they are ‘reaching for the light’, I think that they got a little warm in there by the end of the day, but maybe not. This plant seems sensitive to changes. Also the small sugar leaves have looked weird on this one. Not sure if that’s a nute imbalance, maybe a little too much N from my calmag, not really sure. Next week will be a scheduled ratio change & will be getting less N than now. Maybe too-low PPM overall, but working on that.

Going to start cleaning out some of the fan leaves down low, at least with partial pruning. It looks more crowded in the pics, not so bad when I’m looking at it.

Center-hanging Thermpro over the past 24h: The bump up in temps is from after I raised the light & sensors, & also moved the Thermpro a little closer to the light. If I feel it’s too hot in there now, I might dial down the set point of the temp exhaust fan, or I might physically lower the fan sensor & watch the Thermpro & adjust the setpoint that way. Sometimes if the fan sensor gets too close to the light, it can make it tough to set without causing the fan to run away. I’ll watch how the cab runs & the leaf temps & bud temps on that tallest top tomorrow, & go from there. Leaf temps are still running around 8 to 10f lower than surrounding air temps. The bud temps run warmer, & on that tall top they might try to get too warm tomorrow, so I want to watch for that.

Same Thermpro over the past week:

Into Week 6 since the flip:

Starting to build some buds, & I might have to raise the light up another click or two because the tallest one is getting a little too much light & maybe heat & maybe a little too dry sometimes. Overall this plant has not been looking that great with the look of the sugar leaves, & the bud production seems a little slow, kind of reminds me a little in appearance of the two Super Skunk runs that both hermied, so hoping I’m wrong about that.

Roots: Did a full res-change today & moved into the next scheduled nute ratio. I’ve been running the bucket at around 700 ppm for the past few days, bumped it up to 725 with the res-change today, & we’ll see if that is too much. pH has been around 6.0 to 6.2 with minor adjustments.

Central Thermpro, past 24h: I might have to raise this up a little or raise the light up, since this one is a little lower than the top of the tallest bud now, & might be reading slightly cooler air.

Past week:

Tallest top: Might start reducing light intensity a little early since it’s looking a little rough.

I’ve been wanting to try reducing dli a week earlier than the chart suggests, although I’m still a week away from that as of now. But with the tallest top looking a little rough, I might start soon anyway.

I’ve been making a couple minor changes to try & help the leaf tacoing on a couple of the tops, & the weird-looking smaller sugar leaves. A couple days ago I raised the light another click, but the tallest top is still probably a little too close, & I’m running out of room to raise the light without doing some more work & adding more mount-screws for the top oscillating fans, moving other things up out of the way, etc. So that tallest top might have issues anyway.
But lately I’m noticing some of the leaves on the shorter tops starting to have the same issue, so today I lowered the fan speed of the oscillating fans above the light, which slightly reduced the air hitting the tops. Then later in the day I slightly lowered the target temperature of my main exhaust fan, which helped to drop the air temps about a degree from 84 to 83f max near the tallest top, & without causing a runaway fan.
But later tonight I noticed something odd when looking at the readout of the Thermpro located just above screen-level, which I haven’t been checking lately. It showed that for around the last three weeks, the air has been warmer there during lights-out as compared to lights-on by around 5deg F. I double-checked the heater plates to make sure that they were switched off, but really this is happening due to much warmer outdoor ambient temps in general, & that heat soaking the outside brick walls & keeping the cab warm during lights-out. Not sure how much of a big deal this condition is, but I thought that I’d been noticing the plant transpiring more during lights-out (which seemed a little weird so I figured I was wrong). But I’m pretty sure that it is, & probably this is why. Not sure what the temps are doing mid-level up the plant, & I can add a Thermpro there starting tomorrow, but the Thermpros at the top of the canopy show that the air there is hotter during lights-on & cooler during lights-off, which seems normal to me. But I can still try to lower the temp during lights-off because my temp exhaust fan controller has a photosensor & separate dial for lights-off temps. I know it’s already set slightly lower for lights-off than for lights-on, but I’m going to gradually lower it a little more over the next couple days or so to see what happens.

Into Week 7 since the flip, & she seems happier with cooler temps during lights-off.

Lower Thermpro: Lights-off temps at the screen-level Thermpro went from 79-80f, to around 73f. I made two adjustments to my lights-off temp target over the past two days, & this should be good.

Did a partial res-change today, & will do a full res change in three days. PPM 730 to 740 & I think that’s about max for now. pH 6.2 to 5.8 with minor adjustments.

Tallest top: This one still might end up going crazy since it’s getting too much light & I’ll have trouble reducing that enough. But it seems to be hanging in there for now. Right now the buds at the top aren’t getting hotter than 75f, & the big fan leaves run at around 72f or so.

Top in the back right area: This one seems to have gotten a little better since I cooled the cab down during lights-off.

Full res-change yesterday, same nute ratio but slightly reduced CalMag for a slightly lower N number, & also starting to add a bit of epsom salts for the S, & also starting to reduce overall PPMs slightly from around 750 to around 700. pH running around 6.2-6.0 with minor adjustments.

This is the top of the tallest top, which keeps growing up little by little, & is probably too close to the light…

…so (after I took these other pics) I trimmed the main & clipped the top caylx. Not too familiar with doing this, but probably will have similar results to tops in the past that I’ve repeatedly accidentally bumped & ended up growing out instead of up.

Added a couple guywires to keep things from drooping around:

Some partial pruning of leaves & careful spacing to try & keep the lower stuff going. Was hoping that those small sugar leaves that are bending down would have unfurled & straightened out some more now that it’s cooler in there during the dark period, but they might have too much N or something anyway, not really sure on that:

Chart says to start reducing DLI at the end of the week but the shorter stuff might not like it, so I might leave it as-is for the next few days & just deal with the tallest bud if it starts to act up. Going to think that over some more.

Into Week 8 since the flip, everything is going as well as it could be, not too much drama.

I started the PPM at around 700 with the full res change, & it wants to run up a little each day & is up to around 740 750 by the end of today, which I think is a little too high for now, so I’ll probably run it down to 680-700 tomorrow during add-back & probably try to keep it around there.
pH ran down to about 5.6 a couple days after the full res-change which I’ve learned to watch for, & it usually wants to move down a little bit daily but minor adjustments keep it in check, along with partial 1-gallon res-changes every three days, & full changes every 10 days. That seems to be the most that I have to do to keep the pH in check.

Lower stuff: Been doing partial pruning every day on a few leaves here & there as necessary.

Underneath:

Pic of the tops in the back:

Here’s the tallest top where I chopped the top calyx off. I forgot to grab my Thermpro readouts (which mostly look like the last ones I posted except for an uncharacteristically dry night last night), but watching the bud temps & leaf temps & they are doing well. Leaves are running 8 to 10f lower than the air temps, & the bud temp is a couple degrees higher than the leaf temps. Plant is moving around 1/2 gallon a day. Less if ambient conditions are very humid, more if they’re very dry. The leaves look ok for the most part. Some of the biggest fans on the plant are drooping a little but I just watered before the pic, however I may sometimes be over-watering slightly, &/or PPMs are starting to run a little high sometimes, &/or a little too much epsom salts (started adding it last week), although I only used maybe 1/2 tsp per gallon, if that.

I’ll probably leave the light pretty much where it is & just deal with the tallest top probably getting too much light, because I think reducing the light or moving it up more than a click or two will dim the lower stuff too much. Also I don’t have much room to pull it up much further. I could cut the power from 50% to 25%, but that is probably too dim, so I’ll probably just leave it alone for the most part. I was thinking of making a small shade out of screen just for the tall one & hanging it above it somehow, but I probably won’t get to it.

Midweek update, I had a minor nute-ratio issue as I had realized a couple days after doing the last full res-change that I was supposed to have moved to the final nute ratio.

Not that big of a deal, it’s a difference of about 20% more of the Micro portion of the mix than it should be, & I started to correct it through my partial res-changes every three days. The ratio should be about where it’s supposed to be now after a second partial change yesterday, & it’ll be due for its next full res-change in a couple days. Pretty sure it aggravated the foxtailing, but it is what it is.

Also had a couple humid days & nights over the week, not sure if that helped to cause some bud blow-out too.

One improvement from the last few grows is that I went back to the Viogrow Price-Gouge green training wire, which is a lot stronger & well-worth the extra money compared to the cheaper wet-noodle wire that I had bought off of Amazon a while back.


I’ve been running the PPM around 680 after add-back & it’ll creep up a little from there after moving around 1/2 gallon of water by the next day, but it seems pretty happy doing that for now. I’ll be looking to keep it there or reduce it slightly over the next week, rather than letting it creep up higher. pH has been running around 6.2 - 5.8 with minor adjustments. One thing I figured out some time a few months ago is that I had mis-remembered something about pH Up/Down products & was forgetting that they don’t make up used nutes, but instead neutralize the ‘excess’ remainder to even things out. Once I re-remembered that, I didn’t really change much besides trying harder to stick with the 10 day full res changes & three day partial changes instead of trying to go longer.

Light is still at 50% power & the same height as before, & probably going to stay there until the end. Planning on chopping in a week & a half or I’ll be worrying about nanners causing budrot. Hopefully this thing starts to frost up a little more over by then.

‘Week9 since the flip’ started a day or two ago, & I did a full res-change today:


Been reducing PPMs a little to around 675 after add-back for the past couple days, & it’s been staying there or maybe gaining 10ppm by the end of the day. Been keeping pH between 6.2 & 5.8 with minor adjustments for the most part.

Things are starting to get a little floppy, & I spent time today adding some guywires & supports, & also doing some partial & full leaf-pruning.

I’m thinking that this plant will be getting chopped at the end of this week, or maybe a little bit into Week10. I don’t want any nanners growing in there causing rot or bad tasting smoke, & they seem to turn up around Week10 in this strain if they’re going to, based on what I’ve seen so far.

Looking towards the back, & there are a few more leaves to prune back there tomorrow.

Little Shortie sort of twisted & fell over into the back left corner, so I supported the stalk with some insulation & moved it along the back wall towards the right side. I’ll probably move it back towards the left a little bit tomorrow.

Still trying different things to keep things spaced out:

Lower buds: Maybe these will be dense & frosty.

Below:

Whole thing:

Tallest bud: It stopped growing up after I trimmed the top calyx, but has started again a little. I’m just going to leave it. The top flowers on that bud get up to about 76f at the top. The big leaves slightly lower run at about 73f. Air temps run around 83f around there.

Also continued the experiment where I’ve cut the top calyx on two of the other main buds because they are foxtailing pretty badly in some spots, & I want to see what will happen. Might be too late to tell one way or the other.

Pretty close, closer now on the RH with more plant in there. I could work off of either one as long as I know how they run. But also I’m not against just leaving the one hanging in the center if it’s not getting in the way of the light pattern too badly.

Hopefully this thing stays manageable for another week or so…

Did a partial res-change today, & reduced PPM to 600 from 650. I ran it down from 700 to 650 yesterday. I’ll probably keep it around 600 till the end of the week & then decide if I want to move it down more from there. pH has been running around 6.3 to 6.0 with minor adjustments. Been checking trichs & looking for nanners. No nanners spotted yet, but the trichs are not ready yet either. Still doing minor partial leaf pruning of the bigger fan leaves to get some more light down to the lower stuff.
The top of the tallest bud got up to 78f today. 82f is where I would do something to stop further increase. I turned the oscillating fans above the lights back up to high speed again - about a week ago - whenever I lowered the lights-off temp target. The big leaves a little lower down from the top of the bud are running around 73f. Air temp around there is around 82 - 83f.

Thermpro hanging in center, past week:


Been in a heat-wave with moisture in the air for the past week or so, but the box has been working well. Window A/C in this room has been set to 74f & running in non-eco mode for a while now, but I’m able to set it to medium fan speed at least. RH is about as low as ambient conditions are allowing. If I set my anti-RH exhaust fan lower than it is now, it will usually just run constantly without any further RH reduction unless I get drier ambient conditions.

Into Week 10 since the flip, & she needs more time based on the trichomes, but they are starting to turn. Hoping to chop asap before any nanners start to grow.

Roots: Did a partial res-change today & ran the PPM down to around 530 from around 550. I’ve been running it down from around 600 for the past couple days. pH has been running around 6.0 - 6.4. over the past couple days. It actually ran up a little into yesterday so I gave it a little ph down, & it seemed like it wanted to run down a little to around 6.0 by the end of today, so I gave it a little pH up to 6.2, & I’ll see where it ends up tomorrow. Plant is drinking around 1/2 gallon a day.

Foxtails are a thing with this one. Probably mostly my fault, but maybe a little bit genetic since there is supposedly some haze in it. They mostly seem to be on the wayward side of the brightest light, & I started to notice a few back when the shorter stuff wasn’t getting enough light after a few weeks into flower due to the tallest one stretching so much. But overall the buds seem to be getting fairly dense & looking more frosty, even though there are a lot of foxtails. The tallest bud is in around 1000 to 1100 ppfd, the medium ones are in around 700 to 800, & the shortest tops are in maybe 400.

Starting to see some fade in the big fans:

Was slightly cooler & more humid today (still hot), but it’s going to get hot & rainy for a couple days, then maybe drier for a few days, & hopfully the plant will be done by the end of the week.
Center Thermpro, past week:

I moved my older weed into two big jars from eight smaller jars, & plan to turn the big jars into bubble hash soon. I forget exactly, but I think this was two plants that I finished under the Kind X220 a couple grows ago. I’d have to go back through the thread to figure it out. As I was transferring the bud, I pulled out the densest frostiest tops & saved them in three of the small jars. So I still have 3 out of 11 small old jars. I also have 6 small jars of freshly-cured weed from my last harvest. The older flower is nicely cured, but not a lot of flavor & not as sticky as my last harvest. The newer flower is also nicely cured but has better flavor & is a lot more sticky. Plus I’m basically out of bubble hash. So I think I’ll make one of the bigger jars into bubble hash asap, & I’ll hold onto the other one until the current plant is cut & dried & curing, just in case it doesn’t work out & then I’d probably want to have some more flower on hand.

Time for a full res-change, I’ve been moving thePPMs down to around 400 - 425 over the past couple days. Also reduced cal-mag with the new batch. pH was 5.8 going in. I added more ph Down than I wanted when making the batch & correcting that with some Tussin90 before filling the bucket. But I knew that it might want to run down over the day due to the extra pH down, & I did have to add a little pH up this afternoon. It actually went in at 5.8, moved up to 6.3 by early afternoon, then down to around 5.8 early this evening, & I adjusted it up to 6.1 then, & again to 6.1 from 5.8 before lights out. So one extra pH adjustment & ‘watering’ today. (I usually run some adjusted solution back through the rocks to get everything balanced. I’ve noticed that this can sometimes calm down & cool down a bucket if its flashing. But I think if I do it too often, the plant can get ‘overwatered’, even though it sits in water all the time.)
Plant is still moving around 1/2 gallon a day.

Center Thermpro, past week: Heatwave again, hottest today so far, triple digits. Box is handling it though, & the aircon is still on the same settings as before, haven’t had to make it cooler or turn the fan up to high.

Tallest bud surface temp across the top of it got up to 78f today. The bigger sugar leaves there are running around 74 - 72f, as I check lower. Air temps around there are running around 82 - 84f. The thermpro is hanging a little lower than the very top of that bud.

Shorter stuff:

Things really started floppalating by this afternoon, a few hours after the full res-change & moving from around 450 ppm to around 400 with the fresh bucket, so I had to add some more guywires & green support wires to keep things situated. The right rear top flopped forwards into the front right top, & the front right top flopped against the wall to the right, until I fixed things.

Checking trichomes & looking for nanners daily. Trichomes are clouding up & hopefully will start going amber soon. I’ve been looking at trichomes on the older calyx deeper in the buds & not the newer foxtails, & checking top, middle & lower buds to see how everything is doing. Definitely far from an ideal run so far, but hopefully it will be decent enough. A little worried about the dark green leaves tasting harsh. Also hopefully no nanners show up to taste bad & start rotting. Worst-case if they do show up or if it ends up tasting bad anyway, I can always turn it into bubble hash.

Into Week 11 since the flip, but so far no signs of nanners or any other issues, besides a lot of foxtails. I used a flash for most of these pics & they look brighter than usual.

I’m pretty sure I’m starting to see some trichs on the calyx throughout most of the plant starting to turn straw-colored & hopefully will start becoming more definitive over the next two or three days (30x loupe). I have another three days of addback mixed up, & that might be all she needs. If not, that might be all she gets. Would like to wrap this one up asap. PPM running around 375, pH had been pushing down to 5.5 a couple times over the past couple days, but was more stable by lights-on today, even before I did the three-day 1-gallon partial res-change today. Plant is still moving around 1/2 gallon a day.

Had to add some more guywires to the front main colas. The two in front have three each, & the two in the back have two each.

Was able to remove some of the green support wires, but also added & adjusted some others.

Trimmed most of the leaves off, & the trim will be dried for bubble hash:


‘Sweat-tent’ conditions have been running around 72f-76f, & between 55 -60% rh. I try to keep it on the cooler side, but sometimes it runs up a little, depending on what the A/C is doing. I could get it colder but then I’d be freezing.

Plant installed:


I also made a slightly larger neoprene circular cover. I still have some coins on it to weigh it down & ensure a seal.

I pruned most of the roots hanging out of the sides, & left about 3/4" to the roots hanging from the bottom of the net-cup, although they aren’t visible in the pic. Res is starting at 410 PPM, 6.1 pH. (Plant was seeing 280 to 300 ppm in the passive hydro mini cab.)

Thermpro, ‘center’ of screen: I went in a little after 11 & installed the plant.

Light is at 25% power on both channels, 300 ppfd at the center (not accounting for the small amount of uv & fr that my meter isn’t seeing). Plant was getting around 225 in the Mini Cab.

Did some pruning & LST today:

Pruned to get down to a single top per branch, & LST’ed some of them to spread them out a little & to get them at around the same height. Probably not going to scrog this one & just do what I did last time again by LSTing these through the screen after spreading them apart a little more.

Thermpro at screen-level, past week: (First 24h was before the sensor was in the cab) I reduced RH target by 1% a couple days ago, & will probably do that again soon. For now the leaf temps are running around 3f lower than surrounding air temps.

Roots: They started growing out after a couple days.


The plant is still coming back online after the move & root prune, & I’ve been keeping the RH a little high due to those things, but it should start to transpire more as the leaves & roots grow, & after I lower the RH some more. PPM has been staying at around 400, pH runs around 6.0 & will move up to 6.1 or 6.2 by the end of the day, & I’ll move it back down. I moved it down to 5.8 today, since it seems to want to move up a little daily for now. Tomorrow I’ll do the first 1-gal partial res-change.

Light is still at the same spot & power as last time:
