It worked out great. On days when the weather was mild I rolled the cover back, and harvested some lettuce and let the garden get sun. Then covered it back up. The row covers let in fresh air, and sunlight, so you don't have to monitor as much.
Where do you get the row covers? What are they made of? I love the idea of gardening in the winter!
Oh, that winter garden with the water jugs sounds like a wonderful idea. I may try that!!
