Actually, I only plant a few seeds in each jug to avoid transplanting to other pots before I put them in the ground. When the time comes, I just dig a divot in my garden, carefully cut the sides of the milk jug and then place the whole thing in the divot. I do the same thing with many of the plants under lights. Just a couple of seeds in a pot. This is where they grow and stay until they're ready to go outside. Only thing I need to do is raise the level of the lights. I've learned that if I plant lots of stuff in small cells, I have no where to put them when they need to be repotted.
