High Tunnels

   Four Season Tools offers products and services relating to season extension with fixed and movable high tunnels. We use the term "High Tunnel" instead of "Greenhouse", "Hoop House", or "Cold Frame" to emphasize the importance of using a double covering to maximize season extension in unheated passive solar structures. When the top covering, the High Tunnel, is used in conjunction with the inside covering, the Low Tunnel, vegetables can easily survive through the winter. 

   Four Season Tools is leading the industry with movable buildings in agriculture. Movable high tunnels have many benefits for organic vegetable production and Movable Hoop Coops allow for pasturing animals in contained structure.
