Thanks for the reply Weaselcracker!
I glad you mentioned the stretch, as that is something I worried about timing properly to better utilize the screen. The main stem is still growing at a rate of about 1 1/2-2" a day. Not sure If this is a stretch for the light, or part of the flowering stretch, or a combination of both. The other main stems are growing at similar rate. as the mains grow I am moving them towards the outer edges of the canopy and I'm hoping the many shoots in the middle will continue to stretch through the screen towards the light. The cfl fixture is about 3-4 inches away from the middle canopy, cant lower it anymore because of the 2 T5s on each side. I was hoping the T5s would help encourage the shoots the stretch towards the light. Is this plan legit?
