Greenhouse Grow Jack Herer

[Voodu]

These are my 4 Jack Herer plants I'm going to grow in my greenhouse this year. They are only 40 days old from sowing the seeds. I have started LST on 3 of them so far. Im going to let them dry out a little before I start to tie them down a little more. Happy growing

Second round of LST just finished.

Round 3 for tying these girls down.

Looks good so far. Looking forward to seeing how your JH does. I'm sitting on some Jack Shunk {jack herer x shit/skunk} seeds. I need to pop a few.

Nice! I love a good home grown skunk too. Skunk was the the first strain I started growing.

So I made a mistake. I used cheap salt based fertilizer for my plants. It caused 3 of the plants to have some issues around PH and nutrient burn. One plant the PH was 5.8, it's leaves began curling upward and showing signs of zinc deficiency. It's leaves were becoming darker and thin. Two other plants showed a PH of 6.1 and had standard nutrient burn characteristics, tips of leaves curling down and yellowing, and yellowing spreading from the tips further into the fan leaves. I used the same nutrients in previous years, but this is the first grow I have done in a greenhouse. My thought is they worked well outside because the natural rains flushed most of the cheap and salty food out before they can cause damage. Live and learn.
I gave each plant a thorough flush, I kept soaking and letting them drain until the water came out clear. I let them recover from the flush and fed them some better nutrients from a local grow store. I balanced the PH to 6.7 PH in the nutrient solution. After the feeding and PH balancing, I managed to bump the PH's up by 0.3. All new growth looks very healthy and green and the plant with the 5.8 PH has even started to uncurl it's leaves. Once the dry out a little bit Ill continue watering with a PH of around 6.7, I want to have each plant at 6.5 PH.
I tied them down for the fourth time in LST. The branches in the earlier part of the plant are starting to grow vertically, like new tops. I topped each vertical branch, to help stimulate the main stem growth and to get two heads on each new branch top. The trick is to try and keep the branches around the same height by topping and or tying them down. In previous years, when I did not do this, the plant eventually picked a "new top" and focused it's energy on it[/ATTACH]

My plants have recovered nicely from the bad food. I had to flush one of them a second time but the leaves have stopped yellowing and burning and turned a more light green on the previous damaged areas. I just tied them down for the fourth round of LST. Im going to water with 6.5 PH balanced water, next watering and Im going to wait about another week before feeding them again.

I have fed the plants once since their flush, at half strength. They are growing well, and I have continued to tie them down and top the branches.

I see you have a big bag of soil there, if you put those beautiful girls into bigger pots they will grow much bigger and yield more. They look great, best of luck

Definitely will be following!

That soil is for my next crop of spinach. I hear you on the pot size, the bigger the pot, the bigger the plant. I have grown cannabis in these pots for several years, I typically get them 5- 6 feet tall after the LST before I harvest them in the fall. If they get any bigger, I run the risk of burning the tops of the plants in my greenhouse. It's a converted sunroom, and it doesnt have vents in the ceiling like normal greenhouses, the vents are on the walls. Heat rises, so I try to keep my plants out of the red zone. I burnt the tops of my corn last year when they reached the height of the structure.

2 days ago I gave the plants a full strength feeding of the grow store nutrients at a PH of 6.3. A week ago I gave them a good watering of plain water, that I dropped to 6.3 PH. I would have liked to let the soil dry out a little more before feeding them, but I noticed a few signs of yellowing bottom leaves.

More watering, more tying down, more topping...

Looking great!!
I definitely need to go grab some mutes my plants are way light green now after seeing yours

I am feeding my plants at full strength once a week now. I am still tying down the branches. main top and topping the branch tops. After about one more major tie down, they should be all set for me to let them grow verticle.

 

[Voodu]

I'm letting them grow vertical at this point. Occasionally a new top is selected by the plant, and I tie it down. Other than that, I'm going to let them really fill in now. I should get another 4-6 weeks before they start to enter the flowering stage. I'm really enjoying taking care of these plants, I can't wait to see how big they get!

I've been doing the same to my plant and now it is time to let it go vertical as you said. Any stray shoots that climb too fast I will bend (supercrop). Here at 42 degrees I expect flowering will comence in 3 to 4 weeks.

It's close to 45" in diameter so it's time to climb. ACDC from seed in early May.

Last years Jack Herer grow. Pictures were taken late September/early October. Grown in 25 gallon pots, the smoke was good although I harvested a little earlier than I wanted due to rain. I left the bottom 3 branches for another 3 weeks and that was primo.
