I got a ball about 6 weeks ago and have him in glass aquarium with plexiglass on top and cut out for ceramic heater. I also have uth on same side as ceramic heater. Have probes under substrate(aspen)-heat is 89-92, ambient 86 humidity 51% but cool side is always 77-78. I have no form of heat on cool side but he is always there. Same hides, and got good humidity with misting and used humid hide and got full shed. He eats every 5 days and has never missed a meal, frozen or live he don't care. He has never tried to bite me either. Every once in awhile he is on heated side, but rare. Should I try some sort of heating element for cool side, or is that close enough? Thanks
I also have heating on thermostats with accurite gauges
