C.J., that sounds like an interesting experiment. What kind of containers do you use to keep them from growing all the way to the bottom?
Joe, I start them that early, but I pot up a couple times before they end up in the ground. Each time I bury the plant deeper to develop more roots. By the time I put them in the garden, I have 2-3 feet of stem I can bury. I usually try to keep them cool with plenty of sun in a south facing window to keep them from getting too leggy.
Edit: I like the idea of direct sowing because it's less work. If I continue with my current methods, I don't see how I can sustain it if I increase my production. I only have so many south facing windows in the house and my wife would not be thrilled with me getting grow lights in the basement. Not to mention that I would have to pay to run those lights all winter.
