I just got my BP this week and am working on getting temps regulated. I have an UTH with thermostat set to 93 degrees and a heat bulb on the warm side with ambient temperature around 80-83. The cool side seems to be a bit too cool, usually between 70-75. The last couple of days our house has been chilly and the cool side has been around 60-65! Those temperatures shouldn't persist since it was so cold from roommates moving out and leaving doors open. I've been contemplating getting an UTH for the cool side (set to 82?), but the strange thing is that my BP has spent a lot of time on the cool side, pressed against the glass, even when the temp was in the low 60's. I'm trying to come up with possible reasons such as needing to turn down the UTH a couple degrees? Or the hide on the warm side is a bit big and I can see inside quite a bit, so maybe the hide isn't private/enclosed enough? This morning, I put some greenery between that opening and the front glass in hopes that it feels safer (she often just hides under the greenery on her cool side and ignores the log hide). Or are some snakes really okay with cooler temperatures like that? She's in a 36x18x12 exoterra. I've covered almost all of the mesh top with aluminum foil except for where the heat bulb is.

Thoughts on getting an UTH for the cool side? Should I worry that something is wrong with my warm side that's keeping her from spending time there even when the cool side is too cold? Suggestions? Thanks so much for your help!
