Dawn, if you're interested in winter sowing -- the plastic jugs that kitty litter comes in work great! (I have quite a large collection of them
) And I also suggest checking out the winter sowing forum for more ideas.
Mac, you might be surprised at what you can start by winter sowing. I've actually come to the conclusion that winter sowing is more hassle than just starting under lights the way I have for years, but it DOES let me start more things than I have room for under my six 4-foot fluorescent shop lights.
