So, I made an incubator out of a stryofoam cooler, an Omaha steak one to be exact, I have 3 different thermometers in there giving me 3 different temperatures, 2 of them brand new. They say the incubator gets to about 105 and shuts off then turns back on at 93. How do I get the thermostat more accurate. Im using a 40w bulb and a small cpu fan, Is that sufficient? I am currently trying a 20 watt bulb To see how it works out, My humidity also gets 70-75%ish. Do I need to lower it? how? There are no eggs currently in there I am just trying to figure out how it all works. I only have one vent hole closer to the thermostat. Do I need more? Should I cover that one? its just bigg enough for my pinky finger to get in. Thanks for your time, Brian
