Okay I have plans to get a wine cooler on Wednesday with a glass front, it doesn't work so I am only paying $15, but its a very nice cooler. You mentioned putting water in the heater to increase humidity and also putting water with the vermiculite (which I did look over the how to put together your tubs post), I was curious though about the humidity in general. I saw some posts where people were saying too much humidity is bad, that the eggs can mold. Is that a problem when you put water in the incubator and you have the vermiculite?
