They need to be in smaller pots. Seedlings going into dirt spend most of their energy developing a rootball that is able to support the plant. By starting your gals in solo cups, for instance, roots will reach the inside of the pot much quicker. Not until the roots hit the container side will they start to develop greenery aboveground. By going with a first small pot you are cutting weeks off the time you have to wait before seeing much growth. I start them in 8 oz. solo cups until the larger leaves have passed the cup rim. Then I transplant into 7-inch square berry pots that are about 3/4 gallon. A couple weeks later I TP again into the 3-gallon pots they will finish in. By transplanting early and often I figure I save about 7-10 days of veg time.
Good luck, BigSteve.
