There is a fan constantly blowing on the plants during "daylight" hours. The stems look pretty strong in real life.damn man i suggest u more lights n put a fan in there to get ur stem stronger cuz there starting to look a lil stretced and ur gunna have to tie up the branhces or w/e to keep them from fallin
Every night, I close a blackout shade inside the closet so that no light gets through the cracks of the door... so hopefully it's pitch black in there!gj on the females, be 100% sure u got it 100% lightproof! you dont want to be having hermies
be sure to get clones of them and grow them even bigger!
