1. I would move your themometer down (closer to the substrate) as that is where you need to be measuring the cool side temps.
--- I will do that and message or post it in a couple of hours.

2. You really need to get the top before you start adjusting too much. Most likely you will need to insulate the top so you can raise your humidity up some (50-60%) When you do this it will also have the affect of raising your temps up some.
--- getting the top when the pet store has it (soon)

3. I agree with others seperate the hides to either side with the water dish in the middle (better temperature gradient)
---- moved them.

4. The warm side hide...is it like a bowl (does it have a bottom or is the bottom open to the substate)?
---- It is like a cave thing and is closed in with moss in it.
