Cold Frames for Plants
One of the most useful, and inexpensive additions to any garden is a Cold Frame. Used for a range of purposes cold Frames are basically a small greenhouse used for starting seeds and protecting plants and young seedlings from frost and cold of late winter and early spring. Cold frames help plants and seedlings get a head start before being transplanted into the garden or allotment.
Basically an enclosed box with and angled glass or poly carbonate lid that is placed to face the sun. The lid is designed to open for easy access and also to allow the frame to be propped open for ventilation on hot days. Some cold frames are insulated on the sides and bottom with polystyrene sheeting to add extra warmth. Often second hand windows are used as lids, sliding windows are also suitable and are less likely to be damaged on windy days.

Heating Cold Frames
Cold frame heaters suitable for larger units are readily available, many of these are paraffin heaters.
