Eliot Coleman's double covered beds

Inspired by Eliot Coleman, the author of Four-Season Harvest (He and his wife raise vegetables and salad greens year-round on their organic farm in Maine), we started putting floating row covers over our just transplanted spinach and bok-choi in the green house. We placed flat-topped wire wickets every 4 feet along the growing beds, rest a layer of remay on top of them and use clothespins to clip the remay. This keep the vegetables cozy and warm over night. The temperatures still go down to about 0 at night these days. We haven't been attemping to grow much greens over the winter, however this tested method should be very condusive to growing and harvesting in winter. After all Maine is much colder than Courtenay.
