I've gone from a styrofoam bator to a cooler with a fan and a modified hot water heater thermostat. I have put two water bottles on the bottom of the cooler to use as a heat sync. The fan is blowing across the light bulb to the thermostat, and keeping temps steady at 100 degrees on a bulb thermometer on the bottom. near the top of the cooler where I plan to put the eggs I have a digital thermometer/hygrometer which is steady at 97.8 and 20% humidity, from what I've read these numbers aren't what they are supposed to be. What do I need to do to get the 100 degree temps up to the top? I did put a small open top jar of water on the bottom to see if the humidity would raise, and won't look at it until tomorrow. I will also post pics tomorrow.
