Ok I get it, but it works for me so I'll continue to use them until I run into problems. And thanks for the info,And everyone for stopping by
..if I was using big light in a little space then I can seforhe problem, but I have cheap small lights in a big space so it works. shit I'm smoking mirror grown bud now and am high as fuck right now. But no really I think it would have a lot to do with the size of the grow room the space you have how many mirrors you using how many wattages of light you have and and I would guess maybe if you're in a dryer area it would be different than being in a humid area. The problem is because something doesn't work for someone then they think it won't work for someone else and it might not but it just may work...
