Getting humidity to regulate was a challenge for me for a while. i live in an extremely dry climate so if i didn't make changes then the humidity in my tank could get down to 10%. But I got some spagnum moss and put it in a plastic container with a hole in the lid to let out the humidity and it keeps my tank in the right conditions. It is so much easier than misting every morning and night as well as wetting towels above his cage twice a day. also if you check out this http://ball-pythons.net/forums/showt...-With-Pictures This should help with any other questions you have.
