Step 2: Building your cold frame

Picture of Building your cold frame
1. Get yourself an old window frame with glass. Preferably 3-4 feet wide, so you can easily reach the back.
2. Construct a wooden frame that fits your window frame. Make the back of the frame higher than the front. Remember to use non-decomposing wood.
3. Attach the window frame to the wooden frame using heavy duty hinges.

How do you know at what angle the frame should be? That is, what are the considerations for angling the windows at a 0 percent slope vs., say, a 30 percent slope?

I've read that too great a pitch (slope) causes hot spots that are not conducive to plant growth, while too low a pitch eliminates too much sunlight. In addition, I do wonder why not make a double sided cold frame...kind of a mini green house.

Any insight would be much appreciated as I have some windows that I'd love to incorporate into a cold frame, but am unsure about the pitch issue.
