Thanks for the help guys! Went out and bought a roll today and got my tub all set up. I have my UTH set to 96 Fahrenheit right now but am only getting 86/76 with 61% humidity in a 28 quart Sterilite tub. I have a small water bowl in the back with two hides (one on each side) and am using Aspen for my substrate. Would it be bad to up the temperature on my thermostat? I have the thermostat's probe directly under the UTH under the tank and my thermometer's probe on the inside of the tank over the UTH. I am using a 20g zilla UTH from Petco. Also is 61% humidity too high? Should I add a few more ventilation holes?
