Are we talking temperatures or humidity? If those numbers are in degrees, not percentages. 72 is WAAAYYY too cold. Nothing below 80. EVER. The hot area is perfect at 93.

Do you have a thermometer (not a thermostat) in the cage. (something that measures temperature and humidity?) A thermostat controls the heating device, and should not be in the cage. It the the thermometer digital?

Great job, getting your cage ready prior to getting your snake. That's awesome.
