High Tunnels for extending the growing season

Types of high tunnels include:

Hoophouse or Quonset Style High Tunnel:
​Hoophouse or Quonset Style High Tunnel:

  • Rounded roof profile
  • Can collect snow so space arches close enough to bear the weight of snow. 
  • Sidewalls can be rounded or straight.  Straight sidewalls provide space for taller crops.

Gothic Style High Tunnel:
​Gothic Style High Tunnel:
