The probe on the end of your thermometer needs to go under the substrate right on the glass over the uth. If your not using a thermostat it will read over 94 which will burn your snake, you will need to unplug uth until you buy a thermostat. Uth only heats the objects above them not the air, this is why you put the thermometer probe under substrate right on top of uth. You can keep the temp inside around 84 with a red or blue night bulb or raising your room temp until you buy a thermostat.
