Received a thorough watering as it was quite dry. New growth is looking good, and it will soon be time for a transplant. I could probably let it go 5 or 6 full weeks in the black bucket air pots, but I will experiment with that later on.

It seems to have spread out a lot overnight. The water must have given it a quick boost to grow. I'm eager to transplant, but I know there is still plenty of room for the roots. I can see some sticking out the sides of the holes, but not enough to show that it's out of room.
