Hey thanks for the answer,

My room is pretty hot, that's the problem, it's too hot for us, there always has to be a fan on in the room, I never had problems in the past with heating my reptiles and having my fan on, so it shouldn't be a problem.

the cages sizes will vary, like i said, some adult ball pythons, some carpets (baby or juvi) maybe a woma, etc.

what i want to try and find out is if there are thermostats that can control more than one cage, any ideas?

I really want to find the best non biased reviews possible for the exo terra cages though, cause my other option are the cages that i posted in the link above, they are nice, and have sliding glass doors, problem is I am scared that a snake can squeeze through.

other than that, thanks, and keep the replies coming
