I built an incubator based in Miss Prissy's design, with modifications to the thermostat and thermostat placement as recommended elsewhere. Right now the temps are holding perfect - no variation unless I open the top. However, in one area, the temp is reading 2 degrees higher. If that spot is 101, and the rest is 99, will that be okay? My gauges only read whole degrees, so I don't know what the true variance is. This is my inside set up, except I moved the fan so it blows toward the light. The hot spot is in front of the light. Right now I have store eggs in there so I can get the temps right with the mass of eggs.
