|I have some wood, old glass windows and some window screen I just need a good design to start plants and propogate other plants.|
|Basically, a coldframe is a rectangular box with the back higher than the front, and covered with a transparent roof. You can use scrap lumber and old windows to reduce your costs. The windows available will determine the dimensions for the bed. A glass sash is the easiest to use because it has a conventional frame covering. You'll be building a box with the wood and securing the glass windows on the top of the box. The back wall (generally the north wall) should be at least 18 inches tall, measuring from the top to the bottom. The front wall (generally the south wall) should be about 12 inches tall. A 6-foot frame is a workable size but you can adjust the size of the frame according to the amount of wood you have. You can add weather stripping at the joints to help retain heat and make the frame more efficient. Hope this information helps you build an awesome cold frame!
