HELP! Big plants, little room HELP!

[Melissinmass]

I started these from seed indoors and planted them outside in early June and knew they would get big but some of them are now in trouble! The two plants in the middle have already reached the top of the tent and I’m guessing we are at least a few weeks away from flowering. I need to train them down but I don’t know the best way to do this and I’m worried I won’t be able to get to the back to feed the others once I do. They have a soaker hose running at 5am once a day and I’ve been feeding them biweekly with Fox farm. I have some cages around them now which don’t seem to be doing any other then encouraging to grow up! I live in New England and I’ve invested so much in this grow and I don’t want to lose it due to some rookie mistake! There are 4 different strains growing as well. Please help me get these ladies under control.

Posted this below also as I’m not sure proper edit etiquette

* I also forgot to mention that I had an auto flower that I just harvested early because I started getting bud rot I really need to prevent this from happening to the current plants. I have a few little fans in there now but would love advice on proper air circulation as well as resources for pruning to prevent this or any other ideas! I just got some liquid shade to paint on the outside of the greenhouse and was thinking of spraying all with Neem oil and putting down some straw.

Good morning Melissinmass your plants are loving the environment their in. Now heres what I do when I put my plants back into greenhouse in the fall do to rain and them needing to finish. My plants are in pots so I gently squeeze the stems approx. 12" from tops rolling the stem as I squeeze till I feel it bendable. It will flop like a dog ear nearly. It's the only way I have found besides bamboo poles staked outside of pots and pulling branches sideways. You could selectively remove weak branches also, may slow them down a bit but you have time since in a greenhouse. I've left them in mine till late Oct. here in Oregon. Not sure how hot or humid your area is so careful about leafs overlapping and sweating in there. Super crop is what i'd do. Goodluck

I 2nd the idea of super cropping. If you’re concerned about getting to the back of the green house you will want to make sure to direct the branches to lay down on only 3 sides of the plants, leaving you an alley to walk through. It looks like you have strong healthy plants, they’ll bounce back from the training.

Hi Melissa in Mass ,Im in mass as well I agree with supercroping it wont hurt them and it will increase your yield ,mine have been in my GH since april and I havent run out of height yet ,I top my plants as soon as I can and as often as I can this keeps them with a big flat canopy , but I have had to supercrop before and its not that hard ,if you do snap a branch dont break it off a little tape and it will be as good as new lol if you rub long enough you wont snap it , the plants along the sides are mine I manifolded 4 and did 8 the normal way,the ones in pots are a friends they are all manifolded

Hi Meliss: This will teach you how to train plants in order to avoid the problem you've run into: https://www.growweedeasy.com/low-stress-training-lst

the only way to stop bud rot is to open up the plants so air gets to all the bud sites ,I lollypop mine ,I cut all the low stuff off ,as far as fans go I have 2 box fans ,3 6 inch fans 1 18 inch oscillating fan and 4 20 inch high volume fans 4250cfm , I may have gone a little overboard but this last week end that was 100 , my GH was still cool, I do put hay down (straw was to expensive)
I opened both ends of my GH from the top and have 1 4250 fan blowing from one end to the other with one more blowing out,the 18 inch is in middle isle,2 box fans at end of rows ,the other 2 4250 fans are set in the middle of the rows to push air under plants then the 3 6 inch fans blowing directly on my manifolded plants, there is a huge difference between the air temp at the top and air temp at the bottom but its the volume of air thats keeping it cool I believe
