Tomato Plants - Lessons Learned (yes, already!)

Well, my tomato plants are doing well in their cozy lighted area of the basement!

Here's what I've already learned.

1.  72 tomato plants -- what was I thinking?!  Thankfully, I have a gardening friend who has agreed to swap some out with me as he planted some Jelly Bean, Black Krim, and Purple Prudence, none of which I've tried but all of which I am eager to taste!

2.  Transplant, transplant, transplant.  According to my colleague and tomato grower extraordinaire, I should have already transplanted these as soon as they started growing their first pair of actual leaves.  Which means I'm behind in the game already.  I don't have anything to plant 72 plants into, for one thing!  And apparently I'll probably have to transplant them again before planting because it is only March in Minnesota, after all. 

3.  This is so much fun!  I enjoy taking a peek at them every day to see how they're doing.  You can almost see them growing right before your eyes!

So at this point, between the lights, the peat pods, the seeds, the peat pots and potting soil that I still need to purchase, it's been a bit of an investment.  And worth every penny to be able to extend our short growing season.

So... tomato experts... what lessons have I yet to learn when it comes to starting tomato plants from seed?
