I cut a piece of plywood the same size as my closet and wrapped it with mylar and then mounted six 2' T5 HO FlourosWhat are you using as a reflector? I believe that will cause hot spots on your plants and could be a problem in the future. Reflective is good, but you want it to diffuse the light. Otherwise it focuses little laser beams at the plant.
Your plant looks much better! Very nice very nice. Keep it up, Keep us posted!
Peace
