How to Build a Coldframe - Urban Farmer's Guide
Home > Gardener's Guide > How to Build a Coldframe
 |
Gardeners are master manipulators and have devised all sorts of ways to get a head start on spring and keep growing late into fall and winter. One way to beat cold weather is using a cold frame, which speeds seed germination and shelters plants from frost. The frame is a bottomless box, usually constructed from wood. The structure has a slanted, tight-fitting top made of old windows or other transparent materials such as plastic or fiberglass.
A typical frame will be approximately 3 feet wide and 6 feet long with an 18" inch high back sloping down to a 12" high front frame.
Place the frame outdoors, over a garden bed or against the south wall of your home. Place the frame so it slopes to the north. The sun warms the air and the soil inside, creating a great environment for plants. Sow the seeds for transplant directly in the cold frame. Try propping the top open during the day to allow ventilation and lower it at night to conserve heat. Try placing a thermostat inside to keep better watch over the temperature inside.
