We’ve already had 2 frosts here, and I wanted to continue the salad green season. In this episode we build a cold frame out of easily found materials.
The vent I use on one end of the cold frame is available from Charlie’s Greenhouse, I’ve also seen them in the big home improvement stores, they are used to vent crawlspaces.
You can see some plans for our hoop house cold frame here
Sheperd Ogden has a good book: Four-Season Harvest, that goes into great detail about growing thru the winter, he should know, he lives in Vermont.
