Hoop Garden

Obamafoodorama posts on the installation and use of hoops and hoop covers for the White House garden.

"Fabric-covered aluminum hoops have been placed over the crop rows and these capture passive solar energy and boost the interior temperature dramatically, so the garden soil and air is warmed, and crops can flourish--even in winter. Hoop Houses are often tall enough to walk through, but the White House is using mini versions, about two feet tall, which some farmers and gardeners refer to as "low tunnels" or just simply "row covers."....

But no matter: It's warm and cozy inside the covered beds in the 1,100 square foot Kitchen Garden, and the winter crops, which include lettuces, cabbage, winter radishes, onions, broccoli, turnips, and carrots, are easily accessible, because the covering fabric is held down with sandbags, and can easily be flipped back to weed, harvest, or water, if for some odd reason it doesn't rain (but it'd been raining a lot before it started to snow)"

I'm not sure it's going to be warm and cozy, particularly when the winds blow.  And I still think they'd do better with collards and kale than lettuce, but it's their first year.
