Yes! I checked my plants this morning and it was so hot in there they wilted.. I am going to use a few fans for sure on this. also I noticed that they are hot to the touch, which I didn't know either, I thought all fluoros were cool, but not these. I have to keep them away from my plants now.. so less grow room for me..
you guys think it would be better to use just three of those lights?
this is a pretty good thread, lots of info and it's not boring to read!! i love this place
