It's great for greens that you want to carry thru the winter. It can be hard to access it IN the winter if you are wanting to harvest. I found great success in onions using it. We planted late fall, covered it for the winter, and then had vigorous early onions once the weather broke and had sizable onions well before anything that went into the ground in the spring. Check out Elliot Coleman's Winter Harvest Handbook for more ideas about what to do with the hoops.

We just had a 26' x 84' greenhouse kit arrive today though! So, that will be our spot for greens and other crops that we actually want to be able to harvest during the winter!
