You have to bear with me because my knowledge on diy cob lighting is almost nil. 3 days ago I didn't even know what cob meant. However I think I caught the bug and probably will be building my own system. I've been pouring over everything I can find-here on afn, utube, riu, anywhere I can think of. I've come to the conclusion that this is something I can do. Right now to keep things simple I'm considering one of the Mau kits from Cutters but that could easily change. My question involves the size of my grow space. I grow in a closet that measures 28"x60". Would one long panel just short of 5 feet work in there and if so how many cob's would I need to light it up properly? I was thinking 4 or 5. I typically only grow 3 plants at a time but have done 4. Thanks in advance. Pipes
