This is my first hatch and I am a few hours away from starting day 20. I have kept one of the top vents open on the LG still air throughout the incubation but now I am having trouble keeping my humidity up. I have the reservoir full,sponges, a dish of water(with small pebbles in it) and wet paper towels in there and with the vent open I can only get it to about 58%. I have closed off the top vent hole and it is now at 66%. SO... is this okay to have both vents closed or will it hinder the process and is the humidity okay?
