Hello! I recently got a new leopard gecko. 2 days ago actually. Ever since she came home, the heater has been extremely faulty. I have it plugged into a thermostat, and the thermostat feels generally correct (based on how the ground feels). I’ll set it for 87 and 10 minutes later, the probe will read 90. Great right? I come back a half an hour later and now it’s 103. I’ll lower it a couple degrees and then boom the probe will read 82 . I’ve decided to buy another heater. I was wondering, if I get an infrared thermometer gun and check the temp multiple times daily, do I need a thermostat? Thanks.
