I'm sure that someone has asked this before, but I couldn't find the response that I needed. I have a zoomed UTH correct size for a 29 gallon tank attached to a repti-temp 500 thermostat, which is stuck to piece of glass from a picture frame and taped to the bottom of the aquarium. The tank is a little over 1/4th elevated off of the dresser. I have a digital thermometer with probe on the hot spot and another digital thermometer on the cool side of the tank. The hot spot is reading a steady 91 degrees, but the cool side is 71 degrees. I have read that I don't and shouldn't need a heat lamp for my BP, but the hot spot surface feels warm enough to the touch. The air and cool side feel entirely too cool. I've never owned a snake before and I'm not sure what I'm doing wrong. This doesn't seem like the correct way the cage should feel. Any help appreciated.
