Is it not good to have any condensation on the inside of the tub? I replaced the "too-wet" vermiculite with dry vermiculite last night, but because of the humidity in my incubator, there is still condensation that forms on the inside walls of the tubs. It is a very small amount though.

Those of you that use substrateless incubation, and just use soaked vermiculite underneath your grate...I don't see how you would get no condensation inside the tub?
