Okay, I have a still-air hova-bator in which I installed a pc fan in it which is the smartest thing I have ever did. I can't believe in how much better it keeps the temperature constant. I have it in the garage, (I know it's not supposed to be out of the house) but even in extreme temp swings, from 50 to 80 in one day, the fan has kept it constantly at 99.5. To the question, it's really humid here in Michigan, down right muggy. It's so humid my garage floor is sweating. Being that it's around 80% humidity in the garage, why is it only 34% in the bator? Is it because of the added fan drying it up in there. I know it should have water added to the bottom but when I did, the humidity shot up to 70%. I thought the bator would take on the same reading as it's environment. Any suggestions?
