I had no idea this could be done with the exception of great success with onion seeds planted this way in January in an aluminum pan with a cover. I have always had a problem with enough heat and light indoors during the winter months to get many planted. I am also in zone 6a so we can try together! I am confused about the hardy vs tender annual vegetables (not flowers). I saw the lists:
-WinterSown Vegetables and Herbs (which are the tender annuals?)
-Hardy Annuals Suggested for Winter Sowing (there is a subtitle that says "tender annuals are recommended for sowing a few weeks before your winter season ends", but isn't the list supposed to all be hardy? Also, these are all flowers on the list, no veggies)
It sounds fun!
