this is the first time that growth needs to be stopped
Before I find myself with a forest in my bedroom and some wild animals, any advice to slow down the growth?
I would say you don’t have near enough light to flower a room that size and be up that high above the plants. Looks like you have 2 x 600w HPS’s? They are up very high and your plants are just not close enough to them to keep them from stretching out to them. The further the plant is from the light the more it will try to stretch to it.
Decrease growth ? Well that would mean purposly harming your ladies if you wanted to slow the growth in all ways you would haveto mix a very strange nute mixture you could purposely cause a nute lockout. I would never recommend this. Though if its just the size of the plants your concerned with ie: Height. you can cut them in half and they will still grow and produce. HST is one of the best forms of training. you can even cut every branch in half if you want. though I wouldnt recommend it. What I would recommend is like 2 or 3 more Lights. lol thats a big room.
Top or bend if u have to cover more grow area or put them in flower if u haven’t already done and bend the brenches and if u can’t bend someone top it to last choice , better some stress than a burn cola.
Dajè paesà!
