How to get the best from your 8m tunnel

Ventilation: Build the structure on a slight slope to enhance the air movement end to end. Use windbreak ends in summer.

Shading: Summer shading with a thermal screen fitted internally or externally over the plastic cover.

Hydroponic layouts: The 8 metre tunnel will house 5 double rows of plants in NFT, Growool or Bag culture. The crop is suspended from the wind bracing on wires and the tunnel ends are braced to accept the load.

Heating: Make sure you have twin skin plastic to save energy.
