How to Build a Home Greenhouse

When you are ready to build the cold frame, you should ensure that the cold frame faces south. One good idea, if you're only going to have one frame, is to connect it to the south side of your regular greenhouse wall.

If you're truly in need of the space and plan on building several frames you should have them lined in rows. You could either have these multiple cold frames freestanding or attach them to something. For example, you could attach them to your greenhouse, garage, house, or any other building or structure you have.

If you live in a climate which gets very cold in the winter, it's best to ensure your cold frame has a cover of matting. The type of cover of matting can either be a roll up type or you can even use straw mats. To protect your plants from the harshness of the summer sun, you can use wooden slats, cheesecloth, and shading paint compounds. Any of these will help to keep your plants safe.
