cold frame
Unheated growing box
A cold frame is a low, boxlike structure with a transparent top—usually glass or plastic—used to protect plants from cold weather while allowing sunlight in.
Unlike a greenhouse, it has no artificial heat source, relying solely on trapped solar warmth.
Gardeners use cold frames to extend the growing season, harden off seedlings, or overwinter tender plants.
