A cold frame is kind of like a mini greenhouse. It is low to the ground with a wooden base and a glass top. It is used to protect plants from cold weather. The glass top allows heat to get into the structure and prevents it from escaping.

Ours will look a little more like this
We checked the classifieds and found a used window for $35, it is about 2'x5'.
(it is covered in frost)
This is where we will clear out to place our cold frames. It is best if you place it close to an existing structure (for warmth) on the south side (for the best sunlight).
