Depends, have you transplanted it into a large container? Do so, then let it grow either in sun or under flouro/whatever lights for anywhere from 1-3 weeks. You can take cuttings as it fills out. I would let it go for a few weeks before taking too many cuts. Cuttings 2-4 inches long is ideal, some growers cut em longer, it all works, and your thumb will be green before you know it.
