hi guys. made my first incubator. sorry it looks horrible don't mind the digital thermometer, it reads later than the analog. my thermostat starts the bulb (25 watts) to warm the incubator up to 99.5 F (37.5 C) then wait for the temp to drop 94.1 F (34.5 C) before it lights again. im really sorry. it's the best i can do. now, how do i keep the temp stable at 99.5? or maybe 100.5 to 99.5? the humidity reads 80 for now because of the rain and sudden sunshine. AND BY THE WAY. what do you call this kind of thermostat so i can research about it more. it has a big switch connected to a small plastic box and has a foot-long probe. thanks.
