PssdffJay, I use EcoEarth as a substrate, and have a bit of dry moss thrown in there too. She seems to like it, she can hide under it. I put a bit of the substrate and the moss in the rock, to make it feel more "natural".
I find with the EcoEarth, when you clean the tank and out new stuff in, the humidity goes up quite a bit, since you soak the brick in water to get it to expand. I let it dry out some, then put it in, and try to do it around the time she is going to shed, saves on the misting

The rest of the time, once it is dried out, the humidity seems to stay right on 50%. A hygrometer is a good thing to have, helps me out alot.
Haha, I know what you mean about spending so much money, I have a horse and the snake that are my "babies", and they NEED to have EVERYTHING

Good thing I work at a petstore! :crazy02:
