Ok. So, if I have to set it at 105 to read as 90 on the inside, that's ok? Her thermometer probe is slightly off the glass because of the suction cup. So keep bumping the thermo until we hit 88 to 90 degrees? Then use the heat lamp on the cool side to keep it at 80? (No lamp on hat side keeps it at 65.)
I fear the thermometer reading 90 will actually be hotter since the probe is raised slightly, so should I aim for 88? (Meaning g the glass will be 89 to 90 but the raised probe reads 88.)
