This season, Hornstrider used Root Riot Seed Starting plugs instead of Jiffy Mix to start his tomato seedlings, and his results thus far have been outstanding. Hornstrider reports that he has the biggest, thickest stemmed, healthiest, greenest tomato plants he's ever started!
Since this info could be helpful to people who have not started their seedlings yet (like the folks up north), we opened up a lively discussion on seed-starting methods. Feel free to join us. Catch up on the first thread, then come back and share your own methods here, and post plenty of pictures!
