Planting Seeds on the First Day of Spring

This year I am trying out container gardening.  The method I am planning to use will be based primarily on Square Foot Gardening, which I learned about from a book I received for a birthday present (thanks!).  In my area, the average last frost date looks like April 30 or so, and to be conservative I am planning for May 7 as my planting date.  There is plenty to do before then though: plan the schedule, start growing seeds inside, buy materials, and construct the self-watering containers.

I'll be trying to grow tomatoes, eggplants, peppers, and lettuce.  I began the seeds yesterday for the eggplants, peppers, and lettuce, and next week will be the tomatoes.  Here is a picture of the "indoor greenhouse" I am using to start the seeds (these are peat saucers that you just add water and seeds to):

I am a bit skeptical that this little greenhouse will actually work and am prepared to have to buy seedlings come May.  But it is worth a try, as is this entire project.  I have never grown anything before, but I think gardening will become an important skill to have in the coming years.  At the very least this will be a learning experience, and I'll continue posting my progress here.
