Had to go south to New Mexico for a couple of weeks but the garage was too full of crap to store plants that wouldn't fit in the house for the winter. Temps while gone would range from -7 to 22C. Made a couple of 4x8 cold frames and used some 10 foot wide plastic to throw together some cold frames. A regular light bulb kept the stuff inside from freezing down to -7C, and the plastic, which was stapled to a 1x2 x8' board could be flipped up if it was too warm or the plants needed water. My neighbor agreed to water them, turn the light on and off and open or close as necessary, good guy that he is. Only drawback for me was moving them when no longer needed as being big and flexy, they really needed 2 pair of hands. They extend the growing season by at least a month on both ends, and are cheap and easy to make. If I didn't have the vardo in their spot I would be using them now for starting plants this year's vegetable garden.
