OK, I have made an incubator out of a Wine Cooler with a glass door, used a hot water heater thermostat and a light buld for heat, I have it set, near were it should be.. The light turns off right at 102.0 it takes a few & then turns back on at 100.0, Will that be ok? I am still trying to set it a tad bit lower & I will run it for a few days, I plan on using it for lock down on sunday. What are your readings low & high for heat to come on & go off? I will be posting pics later once i up load them.
