Irrigation Commercial Polytunnel

A Polytunnel means you take over from Mother Nature when it comes to controlling the elements. Which also means you’re entirely responsible for irrigation…something that can be very time consuming. Unless, that is, you let First Tunnels give you a helping hand.

Irrigation is an option for all sizes of Polytunnel but for bigger Polytunnels especially, our advice is to forget about watering cans and hose pipes. They’re hard work. They’re wasteful. And saturating everything once a day…especially in hot weather…is far from being an ideal practice. Instead, we recommend you install an overhead irrigation system. Not only will it make your life a whole lot easier, but you’ll be amazed how quickly it will pay for itself in terms of saved time, saved money (especially if your water is metered) and improved productivity.

Choose Your Spray Lines

This system is available with twin spray lines suspended to either side of the central ridge of the polytunnel, or with triple spray lines. Please select the spray lines required when choosing your polytunnel size.

Each half of a spray line can run independently. A master inlet tap operates all lines at once, giving you total irrigation control throughout your polytunnel. This design also helps with low-pressure issues, allowing you to finely tune the distribution of water to your exact needs.
