So, what I did today is soak some of the substrate in water in a separate tub. Let it sit for about 20 minutes, to soak in the water. Then. removed some substrate from the enclosure, and replaced with this more damp one. After about 30 minutes, humidity shows up at 71%. Being that my girl has some stuck shed on her head anyways, if the humidity stays up there, hopefully it helps. I'll see what its like tomorrow.
Maybe the problem with the humidity is that I never really soaked it. Well, I did to uncompress the brick, but then let it dry out completely. So, we'll see if this helps out.
