I use a google spread sheet to track my seed starting endeavors. It is free to use and can be customized to your needs. My only problem is not updating it once the outside gardening season begins and have to do it from memory, but it is a big help each year. You can also print out copies if you want to keep then in a paper file.

Sorry I tried to get a direct link to mine but it is not working. Will try again on another post.
