The first 2 weeks your plant will focus most of it's energy on growing a little root structure. Those peat pellets don't have any nutrients so it is best to get them planted a little sooner than you did. The cloth won't restrict the root growth. Now that you have them in soil they should start growing soon once the roots spread out a little. They look pretty healthy so nothing to worry about at this point. Just be careful not to overwater them since the roots can easily suffocate at this stage. Good luck with your grow!
