Of the many benefits of hydroponic gardening, and one of the most exciting for entrepreneurial growers, is higher crop yield. Hydroponic crops grow at a rate 30 percent to 50 percent faster than a soil plant under the same conditions.
Cold frames are used in numerous agricultural operations but are particularly popular in commercial growing operations. A metal frame is constructed to fit over your crops. Usually, these frames are then covered with poly-film to protect plants from frost or extreme heat. While not meant to be used as permanent structures, cold frames are an affordable and versatile alternative to traditional greenhouses.
