My ball python is getting ready to shed but I can't seem to keep the humidity up. I have a spray bottle that I use every couple hours because the humidity keeps dropping below 50% and will sometime get below 40%!! I have a 10 gallon tank to start her off (she's still pretty young) with a metal mesh lid. I have a heat lamp sitting on top and a towel covering most of the lid (not too close to the heat lamp). There is a bowl of water in there as well.
I need some safe, easy, and cheap ways to keep the humidity up please! Any comments, tips, tricks, and criticisms welcome.
