Hi,

Keep the probe outside. If you put it inside the snakes sitting and peeing on it can affect the temps.

I am not familiar with the hydrofarm but how are you setting the thermostat?

I take it you have the thermometer probe on the top of the substrate inside the hot end hide and are using tht to find the set point on the thermostat?

Can you test the thermostat is turning on and off correctly using a lamp?
