I just got a temp gun and pinged the substrate right above the uth. It measured to be 110 degrees so I clicked it off, pulled out the little heat lamp, and am using that in the mean time. I bought a light dimmer, but it won't work with the uth. Idk why, I would guess a grounding issue? Anyway, I am thinking about quick fixes while the thermostat (hygrotherm, two birds one stone) comes, since he's shedding, humidity is going to be a problem. Any help?
