Similar to a cloche, this is usually a fixed structure alongside a greenhouse and mostly used to protect plants in pots or seedtrays.
small-scale glasshouse, consisting of a frame and removable glass panels.
Unheated frame used for growing on fully hardy , frost-hardy, and half-hardy plants, usually situated outdoors.
Cold frames are like small greenhouses, creating a microclimate around the plants inside. They serve to protect plants from frost or to harden-off seedlings in the spring. Any number of materials can be used, but generally, wood is used to create a box-like, open bottomed frame. A hinged lid can be opened to allow in air on hot days. The lid is made mostly of glass (or clear plastic) to allow in light. The soil is warmed by the sun during the day and then releases the heat into the confines of the cold frame at night, protecting the plants inside from freezing.

A four-sided structure with a glass or plastic covering used to shelter young plants or transplanted seedlings from cold temperatures.
A low structure with a translucent top, used for protecting plants from the weather and for hardening-off young seedlings.
a structure used to extend the season in the spring and in the fall. Protects against cold and frost. Does not utilize electricity or furnaces or fans for temperature control. At Spring Ledge Farm, we have two cold frames for ornamental plants in the spring and two cold frames for vegetable production in the summer. See Greenhouse.
In agriculture and gardening, a cold frame is a transparent-roofed enclosure, built low to the ground, used to protect plants from cold weather. The transparent top admits sunlight and relies on the greenhouse effect to reflect back radiant heat that would otherwise escape at night. Essentially, a cold frame functions as a miniature greenhouse season extension device.
