Okay I have my homemade styrofoam incubator 95% done and it hasnt cost me a penny. My question is: what do i use for a thermostat? My dad has hot water heater thermos but they range from 125 to 180 degrees. Too hot right? Are there any other things i could use as a thermostat? How bout those circular control switches in your house that are hooked up to your furnace? Would one of those work? I think I have verything I need in my bator. I have egg turner, light socket, PC fan, plastic viewing lid. Anything else? Cody!!
