Recently got a single level rack from Tallgrass Racks for my boy Harvey. It uses belly heat with Flexwatt. I posted pictures of where my probe is and set it to 93 degrees. However im concerned because although the heat tape gets warm and the thermostat claims the probe is at 93 degrees even when my snake is not in the tub my thermometer (back left corner of tub) never goes above the average room temp. Is this normal? I'm not worried about my thermostat being faulty or wrong.
