Thanks for stopping by. Basically, my PC grow box doesn't have to be stealth all the time, so instead of having it closed which only allows 4 CFL's. What If for a few hours a day, I could open up the box and shine an extra 2 or 3 CFLS to the side of the plant PLUS have a fan blowing at the plant? ..would using the 4x CFL completely enclosed be better(by utilizing the reflective mylar) or would having the box open using extra lights+fan be better? Since I understand the further the light travels, the more lumens are lost, i'm wondering if i'll be wasting a lot of lumens by having the box open View attachment 2575162but if it will be GREATLY compensated with the other lights and a fan going?
