The hot spot stays ard 85 but the extreme end of the tub hits 73-74. i am using a temp gun so the temps are all surface temps on the substrate (paper towels). Honestly im not sure how to get ambient temps with the gun. Just point towards the middle from afar? ><

I have no snake in it right now. I am just testing the tub system out.

the middle of the cage hangs around at 75-77. The room temp in my room just goes down at night and im having problems achieving a better temperature.
