Get a jump on the growing season and harvest later with a Cold Frame! Our Cold Frame by Maine Garden Products helps to create and maintain warmer soil and air temperatures than the surrounding environment. Utilizing a Cold Frame in the Spring enables earlier planting, which can result in healthier plants and larger harvests. Fall utilization of a Cold Frame will enable a later harvest and peace of mind during early season frosts and storms. Made in Maine from thick 1.25" eastern white cedar, this sturdy and beautiful design is extremely durable and naturally rot resistant. The Cold Frame utilizes a triple walled polycarbonate glazing for optimal light transmission and insulation. The front panel also utilizes the polycarbonate glazing resulting in a 25% increase in effective growing area. The hinged and pinned top cover can support itself in 2 open positions, withstand moderate winds, and can be folded out of the way. The Cold Frame can be outfitted with an automatic opening device for an additional $50 to protect plants from high heat. The opener requires no electricity, as it operates with a temperature-sensitive paraffin wax sealed inside of a cylinder.
