I bought a "humidity hut" back when my Pied 1.0 was still in his cage because of the same problems maintaining the humidity levels. It was made by one of the Huge Reptile dist's. I forgot which one. It was basically a bowel with a hole that had a lid that could be removed. A day or two after clearing up from "the blue's" I would fill it up with Sphag that was soaked in water, and the first time I put it in there, he knew right away what it was. found him in there the next morning with a perfect shed balled up in side of it. Might wanna give it a shot!

The Reptile store here said if I couldn't find it, you can improvise by using a tupperware container and just make sure you make it non-see-thru if it already is, and to use a lighter to torch the edges of where ever you cut the hole out so the edges aren't too sharp. Hope this helps!
