Reducing ventilation in combination with keeping the substrate dry shouldn't produce any mold problems. It just helps hold the humidity produced by the water dish.I don't like the idea of reducing ventilation because lack of moving air will allow mold to grow.
Where as a tank with a fully screened open top wouldn't hold any humidity for very long, even if you soak the tank.
Where I live it is very dry and arid, so I have to use closed containers, i.e. jars or acrylic cubes, for babies and tropicals. You being in Florida, you probably won't have as much problem with that as I do.
This old peanut butter jar set up would be a good example of restricted ventilation. There are vent holes along the bottom and top of the wall, as well as the lid, but it is still "restricted" ventilation.
