Post-harvest reveg of UK Cheese

This is not your typical grow journal. After finishing a personal-best grow of UK Cheese clones, I decided to try my hand at a full post-harvest re-veg of a couple of plants to see if I can get them to produce enough to get some cuts for clones. I didn't have any room in a tent to take cuts and reveg them earlier in the grow, and I didn't leave much in the way of branches that I could cut and reveg now.

Day 1: I left some branches with small flowers on two of the plants, cleaned out my 120x60-cm (4x2-feet) tent, and moved the plants into there. I setup the auto-fertigation system with high nitrogen early veg nutrients, set the light to a light/dark cycle of 20/4 hours, and hoped for the best!

Day 3: Not much change. I had to adjust the fertigation time a few times to get enough outflow without wasting too much nutrients.

Day 12: Is it possible that those are tiny new green leaves starting?

Day 16: Yes, those definitely are new leaves growing at the top of one of the plants! I am going through a full 50-liter reservoir each week, so this has been quite the effort for those tiny little leaves! Let's hope the rest of the branches get the same idea soon.

Day 17: A few more branches are starting to set new leaves

Most of this new growth includes some floral parts, so it hasn't completely revegged. If I had a third tent, I would be tempted to put one of the two plants back into a 12/12 light cycle and see if I could get some rodelization to occur and convince the plant to make some staminate flowers and pollen. It would be interesting to see if S1 seeds from this cut would keep the yummy UK Cheese traits or revert. Maybe another day.

Day 18: I pruned off the old half-dead fan leaves to avoid getting any disease problems.

Day 19:

Day 20: Starting to get some true vegetative growth, with new leaves unfurling without any signs of pistils or calyxes.

Day 21: Three full weeks after harvest, and UKC1 is definitely starting to reveg. UKC2 is thinking about it, with some odd little furled up leaves that haven't quite opened.

Day 22: Growing nicely. All of the leaves are expanding and looking healthy.

Day 23: Noted some mold or mildew of some sort on the surface of the coco, but only near the rim of pot where the hydro halos don't reach. Drenched the soil with dr zymes. If that doesn't knock it out, I'll see about scooping out some of the coco and replacing it with fresh. It is just a few small patches, but it looks nasty in the microscope!

Day 24: No sign of the mold. I'll keep checking. Still feeding about 1150 EC early veg nutrients at 6.10 pH. Outflow EC is 1377. Everything is copacetic, and I'm loving the crazy leaves!

Day 25: G4r 27°C 60%

Cannabis Grow IMG 9733

Day 26: G4r 26°C 67%

Cannabis Grow IMG 9736 (1)
Cannabis Grow IMG 9737 (1)

Day 27: G4r 25°C 67% Found more fuzzy mold on the surface of UK2. Removed top layer of coco on both pots and drenched again with Dr. Zymes. Rinsed drain pan.

Day 28: G4r 25°C 68% I realized that back when I first found  the mold in UK2 on Day 23, I had turned off the valve to the hydro halo and never turned it back on again. She was already pretty stressed, and 5 days with no water or nutrients certainly added to that! So, starting  tonight, UK2 will get a #5 nursery pot over her head, to give her a full 12-hour dark cycle (with light leaks). If that doesn't causes her to make some stamens, I don't know what will! (Well, I know silver thiosulfate would for sure, but I don't have any. I may have to order some.)

Day 29: 🇬🇧🧀#2 spent the night with a pot over her head for 12 hours. My goal is to stress this plant even further and force it fully back into flower, hoping that the process of rodelization may lead to some stamens and pollen production.

Day 30: G4r 23°C 68%. I removed many of the old browning flowers from 🇬🇧🧀#1 to try to avoid any mold or bud rot. It's hard pruning off the dead parts without also cutting the new leafing branches. I'll keep at it a bit at a time. I may actually see if there are any trichomes left on these flowers and dry them. I've never had flowers that ripened this much!

Day 34: 25° 74%

I gave up on trying to get 🇬🇧🧀 #2 to make some stamens. All the pot was doing was cooking the plant.

Day 39: 23° 69%

No sign of any mold, and the plants are growing great. 

Cannabis Grow IMG 9874

Day 45: 24° 72%

These plants are getting too big! I need to take cuts soon and then flip the bushy one. 

Cannabis Grow IMG 9915

Day 47: 24° 73%

Took 18 cuts from UKC2, cut through nodes with a new razor blade, dipped them in fresh aloe vera and then Bontone rooting powder and placed in the Oxy Clone hydrocloner.

Day 49: 22° 70%

I removed 🇬🇧🧀 #2 from the tent and moved 🇬🇧🧀 #1 to the center of the tent and installed a scrog net. She is way too tall! Once she stretches, I will not have enough height in the tent.

Cannabis Grow IMG 9951

So, I lowered the net down as far as I could and trained the branches out to fill as much of the tent as possible.

Tomorrow is flip day, so she has 24 hours to recover from this not-quite-low-stress training! I'll keep pulling the branches to the sides during the first part of the stretch. My goal is to fill the entire tent with one plant.

Day: 58
Flip Day: 5

Day 50: 24º 68% Lights from 18/6 to 16/8.

Look at how well she is recovering after just a day! The leaves are growing above the net already. I pulled them out a little further to try to fill the rest of the tent.

Day 52:  Lights to 14/10. Filling out the tent, bit by bit.

Cannabis Grow IMG 9977 (1)

Day 53: 27º 60% lights to 13/11.

Cannabis Grow IMG 9982

Day 54: 26º 69% lights to 12/12.

I really understand now why they call this "monster cropping." I am so curious to see what she does now that I have fully flipped the light to 12/12. Will she stretch? How long until she starts popping pistils again? Will any of these branches make anything approaching colas, or am I looking at a sea of larf?

Day 55: 21º 55% Added Bacillus amyloliquefaciens strain D747 to reservoir.

Day 56

Day 57: Temps in tents were 10ºC this morning! Apparently, after I turned down the heat last night when it got too hot, I forgot to turn it back up. Looks like my grows survived just fine, though. In fact, this one is getting out of control. I think some serious pruning of those lower branches is in order, so she can focus on filling the canopy and stretching tall.

Day 58: 24° 63%

This is out of control. I need to get this pruning done, but I don't know when I'll have time. I snipped a couple of the most obvious branches off the bottom. If I had more room in my cloner, these would have been perfect cuts to clone. I guess I will just keep working at it a bit at a time, when I can.
