Wow - all that in just two weeks! You must have a green thumb - I think you need a garden. lol!
I haven't started seeds in years, but I'm thinking of doing it again this year. Do you know when your last average frost date is? If not, you can look it up online. Ours is mid-May, so I'll probably start them in March sometime. I'm sure there are others that have more experience with this and can give you a more specific time.... It is fun though - and way cheaper than buying the plants.
