    I'd think an expensive or production incubator would have a way to monitor O2 and Co2 but obviously a Hovabator or LG does not. I see some discussion of things like:
    I leave the red caps off
    I leave one cap off
    I don't take either out

    with mixed success. How do I know I have the right amount of O2 and not too much Co2?
