Oh, and the store was seriously neglecting her environmental requirements. They kept the entire enclosure around 78-80 degrees, and RH was under 40 on one end and under 30 on the other end.
I've got her (or him) at 90 on the warm end, and 80 on the cool end, with a RH hovering around 60% at about 4 inches off the substrate. I just realized I absolutely need to get a thermostat for the UTH I'm using. Should the probe go under the substrate inside the enclosure?
The probe should be suspended several inches from the ground but not touching the wall. Then use an infrared temp gun to calibrate the actual basking temp. It stops the snake moving or laying on it or peeing on it.
