Types of greenhouse tunnels

A greenhouse is classified by its basic shape. Choose a standard or roll-up tunnel, join spans into a multispan, start small with a hobby tunnel, or grow under shade net in a net house.

Five tunnel types

From a 6 m x 12 m hobby tunnel to joined multispans and shade-net houses. Compare size, ventilation and covering, then open the one that fits your ground.

What growers use tunnels for

Tunnel farming is growing crops in a structure with walls and a roof made mainly of transparent material, such as plastic or netting. The same structure is put to many uses.

  • Vegetable tunnels
  • Tree tunnels
  • Fish tunnels
  • Crocodile tunnels
  • Mushroom tunnels

Built the way your crop needs

  • Single tunnel or multispan
  • Plastic tunnel or net house
  • Hydroponic or soil
