UTH Temps

[Foschi Exotic Serpents]

My probe is tape to the UTH on the underside. There is maybe 1/2 inch of substrate or less it is reptibark.

Which probe??

The thermostat probe should be taped there. On the outside, directly on the underside of the UTH.

The thermometer probe, to measure and monitor your internal temps, should be on the glass, inside the tank, directly over the UTH. If the UTH is large enough, and the bedding is not too deep, a surface reading of 90/93 here should be fine.
