Welcome to Ledgewood Farm Greenhouse Frames. Ledgewood Farm, located in New Hampshire, manufactures pipe frame greenhouses and high tunnels. The frames are used by all areas of agriculture for plant protection, livestock housing, and storage. Our goal is to help make your business more profitable by providing frames to enhance plant growth, improve the health of your animals, and create economical storage. Season extension for vegetable farms is an important economic boon for retail and wholesale production. Heated greenhouses and unheated high tunnels fill a void left on many farms to extend markets for many weeks. Season extension works for many crops including vegetables, small fruit, herbs, and tree fruit. The greenhouses are suitable as plant protection from seed to sale. The frames are an economical alternative to wood or steel buildings to protect equipment from the weather and to decrease animal stress during cold winter months.
