they are about 10-12 inches tall, with what seems to be 6 main colas (im not sure, I topped it at 2 weeks old and thats what happened), they are now 4 1/2 weeks old
Those pots have tons of space for more root growth. If you have cieling space I would hold off for a couple more weeks. You will have a much better harvest if you let them bush out a little more.
