IMG 1174

A Commercial Cold Frame Greenhouse is one of the simplest forms of greenhouses. The Cold Frame Greenhouse uses no artificial heat source, but depends on the sun filtering through the single or double layered plastic for heat. The Cold Frame Greenhouse (which has been called a Hoop House or High Tunnel) is not only cost effective structurally, but proves to be a great supplemental growing space. The Cold Frame Greenhouse is available in free standing models, made with extra heavy galvanized structural steel tubing, as well as, having side curtains and end walls for ventilation. During the hot summer you may want to add a shade cloth, with 50% shade the inside temperature can be reduced by as much as 4 degrees.
