I have my BP in a 15 gallon critter keeper tank (slip lock lid).

I have a UTH, Day light heat bulb, ceramic heat bulb and a moon light-for tropical night temps.

Humidity is usually around 35%. I do spritz her fake plants every morning to up the humidity since it drops a bit during the night. She has lots of fake plants and a huge branch in her tank, as well as a half log where the UTH heater is.

My problem is this. I have a digi therm/hygro and it says my tank is always at 81 degrees on the side of the UTH. The cool side therm says 75.

Grim is happy, active, a great eater, and the like. But I see you all talking about higher temps, when one of my BP books says to keep them between 78-85 degrees ambient temp with a basking spot in the 90's.

Am I doing something wrong?
