I do this method as well while waiting on my Animal Plastics enclosure to get here. Spagnum moss covering his third hide on the cool side. The humidity in there is about 10-20% higher than the rest of the enclosure, so he can get in there if needed. This is a quick fix but doesn't eliminate the need to mist still. As other's have said, def look into a PVC enclosure. I also used tin foil with duct table on my screen cover which helped a lot.
