I had my girl set up in a 41qt tub, had cypress mulch(or you can use orchid bark) and mixed it with some damp sphagnum moss on one side of the tub over the heat. then got a smaller plastic container that fit upside down in the 41qt tub, big enough to go around the girl and eggs both with and length wise. Cut a hole in the small tub for her to enter through, bury it so it touches the bottom of the 41qt tub and fill the substrate in around the hide (leave the substrate inside the hide too) place probe under the hide to monitor temps. I sprayed around the hide every other day more or less, I didn't worry about humidity too much because of the substrate and moss. I think mom can also bump the humidity up if needed if there is not a huge depletion of it, by soaking in the water bowl. I hatched out 5 healthy babies, one is now one of my breeder males. I have two clutches that I did not think were going to drop this year; one less then a week in and one about 20 days in, i'll see how they come out.
