you will be very unhappy with a styrofoam incubator...I have trouble with temps just from the sun shining in the window,,,,,this is the reason it is my hatcher,,,it only need to hold temp for a couple days
Wing and others.....I just set my cooler bater thermostat up. Its an STC-1000 and its accurate to .1 degree C....I have mine set at 99.5F and 100.4F....it goes off for about 45 seconds while the temp drops to 99.5 then comes back on for about 2 mins till it goes up to 100.4....beyond what I set there is no variance....I guess some store bought baters don't have the heating capabilities to catch up...seems a flaw in the unit...I am using x2 25W lightbulbs....
