Oh, I should have explained better. In addition to the Zilla digital probe that measures my ambient tank temp and humidity, I have two digital probes, one under each hide in the substrate measuring the warm and cool side temps.

Yes, my backing is the exo terra rockwall, thanks for that. I like it because I can hide the wires of my probes that go in the substrate.

Thanks everyone for your suggestions and sharing your experience! I haven't turned the light on today and so far my humidity is staying at 56% so I think I will lose the light. Maybe that's just what I need. I think the light was still being turned on by the kids, perhaps.

I know from reading a lot of the posts that tubs are much better but I like the aesthetic value of the tank with my set up. If I can get the tank where it needs to be and keep our BP healthy than I want to stay with the tank. If I can't maintain it then I will have to seriously consider moving to a tub.
