 I'll water them. But even seedlings, every other day is sufficient. Three times a week is generally sufficient. If not, you can spray it down with a hose. You don't need to run your whole system. If you've got a lot of new plants going in, you may have to increase your amount of watering. But again, typically three times a week or sometimes I'll add more with a hose. But if I overuse my system, then I get shallow roots.
