Featuring strong galvanised steel frame and guttering and ‘Solarweave’ cover film, The Commercial is our ultimate GROWTunnel system designed for commercial-scale growing operations.

The controlled growhouse environment of The Commercial allows for a more efficient operation, reducing crop losses to pests, providing a longer growing season and higher yields than exposed field farming, protection from wind borne diseases, pathogens and spray drift. The Commercial GROWTunnel also provides an easier transition to organic farming practices.

The Commercial GROWTunnel is constructed from hot-dip galvanised steel and durable ‘Solarweave’ 15-20% shade 160GSM cover film. Climate and ventilation inside the tunnel are easily controlled with 10 in-built 1000W extraction fans, roll up sidewalls with UV stabilised insect mesh, dual-end double-layer sliding doors with internal insect mesh, side roof vents with insect mesh and retractable UV stabilised shade net. 

The integrated rainwater collection guttering, spanning the 40m length of The Commercial provides a closed-loop system, enabling growers to harvest water to replenish their crops. 

Become completely self-sufficient and automate your growing system, with optional extras including solar power integration, digital irrigation system and smart farming sensor technology.


The Commercial must be installed by one of our approved construction partners. Full instructions can be provided for those with proven construction experience.
