Our house stays between 70-72 all day and night, and I keep the incubator on the kitchen counter where I can monitor it frequently. I will know to stay away from styrofoam incubators from now on. I'm a student nurse and just don't have a ton of time to experiment with trying to get it to work. So aside from ambient temp, is there anything I can do to prevent fluctuations?
You could change out the thermostat with a digital electronic one. they have a tighter range of temps.
