View Cold Frame Lid Background. However, the lid can always be lifted if the weather gets too warm. The cold frame i built 25 years ago is still working great (visible in the background of the photo).
A cold frame is simply a box frame with a clear lid (also known as a 'light') on top.
Cold frames can be bought or constructed from timber and plastic, but cold frame lid. They allow you to start planting weeks earlier in the spring and to extend the fall harvest past the hard freezes that would bring an end to crops in unprotected beds. The lid should fit snugly on the top of your box. When choosing salvaged windows or doors for your cold frame lid, make sure that the surface area has small panes.
