A few of things.


1. I would move your themometer down (closer to the substrate) as that is where you need to be measuring the cool side temps.
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.
3. I agree with others seperate the hides to either side with the water dish in the middle (better temperature gradient)
4. The warm side hide...is it like a bowl (does it have a bottom or is the bottom open to the substate)?

Let me know on #4 as I may see another issue.
