Hmmm.. Makes sense. Lets take it a step further.. What if the room is the size of a closet that is 40"w x 40"d x 8feet tall. I have this old closet of mine that i dont use anymore. IT has 8 shelves built in it already. The other day i got the idea....hmmmmm maybe i can switch this into a snake room. But im unsure how i would heat it up....without a heater duct. As far as ventilation goes under the door is a good 2inch gap as well as all the way around it is not a tight fit haha. I can also put a fan inside. I suppose i could just run a light inside and see what kinda temps i get. I just wanna make sure i dont start growin mold. This might be a trial and error project with a made up cage and no snake in it to see what its possible of handling.
