I know a lot of you use the 1588 Genesis. I am wondering if it uses the wafer type of thermostat?? I have a 1602 Hovabator and was also wondering if any of you think I should try to modify it by adding a fan??? Do you think it would work?? I wish I had a 1588 , but I was given this still air one for free so I am trying it. Any input is appreciated.
