Well, I have been searching and searching for JUST the right humidity control for my incubator. I am going to sell my LG and build my own multi shelf unit out of hardwood, lined with styrene, and skinned with a gloss laminate. Here is what I am installing for humidity. It is DEAD accurate, as it came out of "hosptial surplus" used in a human baby incubator machine, so humidity control is precise. The best part is, I can pick these up All day long at about $40.00 each. It has the digital control, humidity sending unit and regulator which installs IN the incubator.
