When the lettuce seeds germinate is it safe to prick them out to where they will finally grow,
You do not say where you are but I would say it is a bit early to do this.
But having said that if you have some on the go you can prick out a few into individual 3" pots and grow them on in a cool greenhouse or cold frame until it is the right time to plant them out, this will give you a head start!
or should they be sown into where they will finally grow,
Too early for this! This link might answer your questions better;
