GCG Cold Frames for Season Extension
Cold Frames are like mini-greenhouses that fit on top of your raised-beds or can be placed directly on the ground, trapping heat from the sun to maintain a warmer environment than outside. During the winter the temperature inside the Cold Frames can be up to 40 degrees warmer than outside, promoting healthy growth and keeping plants alive year-round. With cold frame technology, you can extended your growing season into the late fall and early spring, with the potential to harvest year-round.
Cold Frames make growing in our Northern climate less of a challenge. Cold Frames are installed at the beginning of October or the beginning of March, depending on when you get started. Our cold frames come with a heat activated automatic arm that opens and closes the lid, which is critical in the Spring and Fall as temperatures fluctuate, allowing for the highest possible success rate without constant monitoring.
