I keep about 1/4 inch of water in the bottom and I keep the clear top on. The pots with the different seeds have holes in the bottom to keep the soil constantly moist. I keep them like this until it is time to let them dry out more. I grow them in my greenhouse where the temp varies from near 100 to 68 degrees so far this year. I would assume that once your seeds establish roots they will need to get nourishment in your mix.
