Well, which is better, stable temps, but cool...or hugely varied temps, but sometimes warmer? LOL. Those are my choices unfortunately. There is absolutely nowhere that will be able to be 70-75 degrees in my house. Ever!
Can you use a heating mat or pad to set the incubator on to help keep it a bit warmer?
