I'm growing several varieties from the Dwarf Tomato Project this year. I'm wondering if I should start them earlier than my standard tomatoes? I normally give my tomatoes 5 weeks from seeding to transplant - as they get too big otherwise. Since the dwarf's are shorter in general I'm wondering if I should start them earlier - say 6 or 7 weeks? If anyone has grown these from seed, I'd appreciate hearing your experiences. Thanks!!!
