Larry, I've read before that tomatoes benefit from potting up -- but I wonder if it isn't more because they get planted more deeply each time and get more of a root structure, rather than the actual act of being transplanted. So, what I'm thinking is, it may be every bit as beneficial - and maybe more, since they wouldn't be getting disturbed - just to start them in a larger pot with just a shallow layer of soil, then keep adding more soil as the plant grows, as you mentioned. I don't really have room to do that with all my tomatoes because I start them and a lot of other stuff under lights in the house and can't move them out to the GH until about mid April, so I need to use small containers (6-packs) for the seed starting and then move them into bigger pots later on, but I think I'll experiment with a few to see what happens. LOL, yours should be about ready to plant outside when I'm just starting my seeds !
