So let's talk about creating a micro-habitat to grow your delicious, nutrient rich greens in the winter. Some people have experimented with cold frames, which are essentially boxes or low hoops along the ground, covered with plastic or glass. These work, however, if you have the ability to build a backyard hoop house, such a structure is infinitely better. You can see that this double-skinned, insulated hoop house has stayed warm enough all winter long, to keep these lovely greens and vegetables alive. Many of these things were planted in November, and now we're enjoying them every night of the year. Essentially, the way the hoop house works is this, the double skin of plastic collects the light, and collects the heat, and holds on to it, similar to the greenhouse effect, and warms this inside space, approximately fifteen degrees warmer than the outside temperature, so if it's a cold winter's night, in here the plants are cold, but these greens are all very cold hardy. We're talking about plants that can withstand temperatures into the twenties and below, so you're providing a small micro-habitat, in order to keep alive some of the most delicious and nutritious food possible.
