If you have a vegetable garden, you would want to build a cold frame to extend gardening season or get a headstart on spring planting. This garden tool is a type of miniature greenhouse, which is made with glass or plastic that lets plants absorb sunlight while trapping heat during the cold weather to prevent wilting.
If you want to learn how to make your own cold frame, you can check out this tutorial at HGTV Gardens. You’ll only need a few handy tools, wood, old window frame and a foundation vent preferably temperature sensitive.
