Today we took up the task of building a cold frame to extend the growing season. So we took off to the barn to look for materials that were laying around. Our efforts provided us with wood and several old wooden windows that we have been saving. I didn’t do specific measuring, so I will give you the generic version
First we set both windows on the ground to provide us with dimensions that we would need. We selected four pieces of wood for the sides of the cold frame. We chose a wider piece for the back and a piece not as wide to form the front. This gave us a sloping frame that we could face toward the south to maximize the sunlight exposure.
We laid the two windows side by side and the four pieces of wood on their corresponding sides. We then marked all dour sides in prefer to make the proper cuts.
The front and back were about 52 inches long and the sides were about 40 inches in length. The back ended up being 14 inches tall. The front is 12 inches tall. We would have liked to have more of a slope, but we wanted to create the cold frame for very little cost.
After cutting the four pieces for the frame, we found a 2 x 2 to make four corner stakes. These were cut to make four 2 foot long stakes that were pointed on one end.
We then drilled small holes in order to help get the nails started. The wood that we used was extremely hard, so much so that we bent several nails. Once we got the four sides nailed to one another, we set about attaching the comer stakes. These will serve to drive the cold frame into the ground and keep it in place. In order the keep the frame together and hold the stakes in place, we attached two c-clamps to the stakes and sides. These clamps kept the stakes in place as we drove the nails through the side panels and into the stakes.
Above you can see our stopping point for the day. The stakes are sturdy and the windows are resting on the top. We will need to add hinges and then located a prop stick, but the project is nearly completed. Now to finish up so we can set the plants in place.
