So I have a hydrofarm thermostat to regulate my UTH. I use a zoo med thermometer to double check the temp on the thermostat. They were pretty close to each other the first few days I had them set up (within 1-1.5 degrees). However, recently the thermometer has read about 3-4 degrees warmer. I checked to make sure both the probes were next to each other, and they are. Is this typical, or is something wrong? Thanks.
