This setup will be for a panther, My idea is for the fan to set about a foot away from the side of the cage pushing air left to right along the bottom third of the cage, I will also have a mistking system to maintain humidity. As I said the cage is in a closet, but the closet is 4 foot wide with no doors and the cage is 2 foot wide so it's not like it trapped with no ventilation, I just thought some extra could be good for the cham and plants. I will have umbrella plants, pothos, hibiscus and maybe a jasmine.
