Cold frame just a fiberglass sheet.

This cold frame actually sits up above the ground like a table and is perfect for starting seeds in the winter. And the fiberglass and along the seam where the material contacts the horizontal 1 x 2 s will help to retain heat. With a clear acrylic sheet on top plenty of light hits the inside and there s a handy shelf underneath which provides a little extra storage space. It can also be purched from charley s greenhouse supply to the covers.

A cold frame can be any width that the lights will cover and any length or height. The frame can be constructed out of many materials but wood is the most common choice. The bottles are used as the side and the top for the cold frame. Step 3 construct your frame.

Decide on the width depth and height of your cold frame so that you can buy the right amount of wood as well as the right size transparent sheet to go on top. The frame should be just tall enough to clear the crops you plan to grow. To control the temperature in the cold frames i decided to attach univents made by solar vent works. Univents are odd looking aluminum linkages powered by a temperature sensitive cylinder that raises one end of the cover about a foot to prevent the frame from overheating.
