plug it in, heats right up to 100. . . then 110 then 120 adjust it the tiniest bit, plunges to72 ( house temp) repeat. I put a new therm/humidity digital gauge in at shelf level and its reading cooler, it is mostly staying at 97-101 degrees. Humidity is staying where it needs to be. the old therm. is sitting about 2 inches below the heating wafer and is holding at 110. OBVIOUSLY this is not a good scenario... but... do you think anything will hatch? should i worry? I plan on eventually putting in a really nice thermostat. but i have eggs in there now!
