Should I flower and wait 2 weeks till after stretch is over, and did u mean 3 in or 3 feet. I already arranged the tall ones on the edge. Or trim them now I would think after flower. Also do u think I would lose much yeild by flowering the first 2 weeks with 1200 watts to reduce stretch and then turn the other 2 bulbs after stretch is over. I have 2 growzillas on a light mover. Thanks
