I have a couple small suggestions. I keep mine in tanks and fight the same problem. 1 make sure the water is near the heat source. 2 something I tried that made a world of difference I took a small plastic container and made holes around the middle with about an inch in between. I soaked some repti bark then put it in the conainer put water to just under the holes and put it by my heat source (next to the water behind the hide). I havent had to mist once I just refresh that water everyday when I clean the water dish.
