Thank you so much for your response!
Here is my info:
I am using an UTH mat and a heat projector bulb both connected to thermostats on the warm side. The UTH is on the outside of the tank on the glass while the probe is on the inside glued to the glass.
The warmest ambient is 88 and the coolest is 74
The UTH glass spot is 86ish
84 in warm hide
74 in cool hide with 70-80% humidity
He’s burrowing on the warm side. I just checked and he’s back in the warm hide itself so no longer burrowing in substrate.
The thing I am struggling with is humidity regulation, I mist everything at least 2-3x a day. The cool side with no lamp stays at least 69% while the warm side can sometimes drop down to 50 which I try to fix immediately. I try to keep both at least 60.
I have a 20g glass tank with a mesh top lid and I use a mixture of fine coconut fiber and cypress mulch. I keep a plastic sheet over the mesh on the cool side right until it gets to the lamp. I try to keep a damp towel on the edge of the mesh on the warm side as well, I’m just not sure how to block the humidity in around the lamp.
