The humidity in my ball python's cage is much too high (68%-78%). I'm using aspen substrate and a small deli cup as a water dish (can't go any smaller) placed as far from the heat source as possible. The heat source is flexwatt placed underneath the cage. The cage itself is an Animal Plastics T8 with sliding glass doors. I live in western Washington state, which is probably why it's so humid right now. It's also been kind of foggy and rainy, typical weather here. Any ideas on how to lower it to an acceptable level?
