Be sure if your using substratless do not use press n seal. It causes WAY too much condensation on the sides and lid of the tubs. Substratless can be water for medium. As long eggs are not in the medium it can be as soaked as you want. I have never had to add water to a tub during entire incubation due to the amount of water i add.

If your not using the substrateless with the crate, but eggs in the medium then i HIGHLY suggest the press and seal since the medium cant be wet but moist.
