I'm going back to get the digital thermostat tomorrow. This dial one has way to big of a range when turning on and off.
As for now peeling away the heat mat and putting the probe between it and the glass: 1. Will the mat restick to the glass?
2. Does it have to be stuck to the center of the mat or is the edge-ish ok?
3. Will it make the spot of the mat where the probe is, less effective, since hat spot is now not stuck on the glass but instead stuck on the probe?
4. What do you recommend I set the thermostat to? 92? Then see what the surface temp reads? And as long as the surface is between 88 and 91 it's ok? (I do have the 50 watt ambient black light to aid in the surface reaching the correct temp (and for viewing.)
