you got a while. Wait till yu get a few nodes. Wait till it looks like a plant and not a baby weed. When it looks like a plant yu will know. Then I bet you can wait a week. Lol, yu dont want to move it when it is so small as yu will damamge the roots. I once used a clear cup inside a colored cup. The roots grow and grow fine for a few weeks in a cup. It is better I have read to start in a 1 gal, then move to at least a 5 gallon. i am trying a one to seven gallon and that is where I wished I had started, BIG!
