In some places, like where I live, winter only means that the mid day temps get to low 70 degrees. No good for cooling. AC year round!!!!!
I like that winter air idea, but it wont work for me too well. Beacause of my grow location, the winters here are cold enuf but no way to get the cold air into my grow. A\C is not very affordable or stealthly for my needs. I was thinking some kinda wind tunnel\ cooling chamber. but thanks for the suggestions, and more ideas are definately welcome.
A cool tube will channel a lot of the heat from your light out of the grow space. Portable air conditioners run about $300.
