I really don't like the idea of humid hides because ball pythons are not meant to be in that type of environment. If they sit on wet substrate too long they can get scale rot. I would just figure out what is wrong with your set up that is causing you to need a humid hide. My guess is a heat lamp or some type of heat emitter. They are very hard on humidity, but may be necessary to keep your temps up if you are using a tank.
