The reason behind not flooding at night is plants don't take up any nutes or water at that time. Reason I do is I don't like leaving roots to dry for more then 6 hours. So I flood once. Also in a ebb&flow system later roots can be sitting in water without air. So flooding once every 6 hours will give new DO in the water. But other then that there is no need to flood. It's so cheep to do so I won't change.
