I agree with this. Although I don't have a glass tank anymore using damp sphagnum moss in a hide box worked out the best for me. I even moved some mulch over to expose the glass, filled up the empty space with moss, and then added a hide above it. It created sort of a sauna effect being that It was underneath the heat lamp. As long as you keep it damp and not really moist you shouldn't have a problem and the sheds will be perfect. During the winter misting and covering almost the whole top still wasn't working to get my humidity up until I added moss.
