I usually start mine in November, inside in deep pots, under the lights. I started mine in September last season because I was too excited to wait.
I think many folks don't like messing with them for that long. I am not sure the seedlings were much bigger starting them early, but I didn't care. I move them out of the basement in April, and plant by the end of the month.
I say, do what makes you happy,
Steve
