How Often to Water?

How Often to Water?

Wayyyyy noob gardener here. This year I bought one of those little "greenhouses" at Home Despot that holds 30 small peat pots. I'm starting bibb lettuce, carrots, tomatoes, bell peppers, and jalapenos. So far my lettuce have started to sprout and this morning I had a couple of carrot seedlings peeking through the soil. How often should I be opening the lid and watering? Should I only be spraying with water? I don't want to over/under water them. We're moving into our new house in 4 weeks so soon thereafter I'll be transplanting them (according to the seed packets anyway). Is there anything else I should know/do?
