I made a humid hide by cutting an appropriate size hole in an appropriate sized rubbermaid container (Kind you would refrigerate your leftovers in) with a cordless drill and a 1 1/2 inch hole saw. I spray painted the container black, let it dry and air out a few days. I only painted the outside with the lid on. You can purchase a can of spray paint that is made for plastic. Then filled the container with Reptile moss that i sprayed with water. The hole that I cut was on the lid. But you could cut in on the side of container. Worked great for me and they seemed to like the hide.
