Re: Cold Frame Gardening

What I found useful if you have the time is to cover the glass on clear nights with a cardboard onto which aluminium foil is fixed, the aluminium foil facing down.
This will reflect back the heat from the ground instead of having it radiate into space on clear nights. It was seven degrees F less cold under the foil than under ordinary glass or plastic.
