Hey what's up guys I have a vertical grow room that's a octagon that I made myself and everything is well I'm just trying to come up with a idea to block the light from clones that I just put in the system. I use a cooltube with 1k hps and I am unable to raise the light away from the plants. I was thinking maybe some window tent film that's let's say 50% made into a cylinder shape to go around the cooltube without actually being on the glass. I'm just looking for some ideas. Thanks in advance guys.
