High temp control / greenhouse
I just bought a house, and it has an attached greenhouse! I'm thinking of moving my 12-gallon planted/shrimp tank into there, and eventually expanding to a 50-gallon in there as well.
My question is, what methods are there for COOLING a tank? The greenhouse gets up to 75 in the dead of winter, and I am not sure yet how hot in summer. There is a circulating fan, and soffits that open up to the outside. The house itself has central air, so I am thinking the greenhouse will usually stay around 75-80.
Thanks in advance!
