I repotted today. I was hoping between that and getting an air cooled reflector my temps would go down, and my plants would get nice and green again.
I repotted, watered, got high, had lunch, etc, and when I came back about two hours later after repotting, my temps are holding steady in the mid to upper 70's, and my humidity is slowly rising...so that is awesome. I might hold off on getting that air cooled hood. If I don't need it, its $100 less I need to spend. I still may get one, but for now I think i'll keep it as is.
All I can think of is that with the plants being spaced differently, there is more air flow, which leads to lower temps. And with bigger containers and more soil, there is more water, so the air gets more humid
I'll get some pictures taken later.
