Thermostat arrived - not working right.
Hi, everyone. I purchased my HydroFarm Thermostat on the 12th and got it on the 15th, and I set it to 90 degrees, and I put the probe outside the tub, between the tub and the UTH. I have two thermometers on the hot side, and then the probe in between the UTH, and tub, as I said.. The two thermometers say 75 & 76.2 degrees and the thermostat says 90.3 degrees. I then moved it into the tub, under the bedding and & directly above the UTH. It then read around 90. kept fluctuating from 88.9 - 93.5 and the thermometers still say 75-80... Why is it so far off? It's starting to agitate me.
