It's actually kinda difficult to underwater seedlings in starter cells since the soil retains more moisture than is apparent.

So long as the surface dries out at least once a day, you're fine. When I'm starting, I check for surface dryness every morning and if a cell surface is well dried, I give the cell a shot from a syringe. (Easy to control and easy to reach the cell.)

The nasty effects of "too wet" don't happen when the surface is dry for a good part of the day. The nasty effects of "too dry" are crispy seedlings, so err on the side of too wet.

Now go use that Greyhound bus ticket.
