The directions that come with the hovabator say to just fill the little middle well.....if I just fill that one, the humidty for the past day and a half have been only 30 percentish....I then filled another one of hte slots in the plastic liner and this brought it up to 55%. I know that Metzer farms and the other websites say it should be much much higher....Any thoughts? Even though it says to not fill the other wells, surface of the water is what increases humidity and I don't know how I will incresae the humidity without doing this? Any thoughts?
