How To Build Your Own Polytunnel to Grow Food All Year
0

Polytunnels seem to be popping up all over the place – and with good reason! They’re a fantastic gardening tool that can increase crop size, extend the growing season, and protect your plants from the elements. And, you get all of these benefits without the hassle that comes with erecting a permanent structure such as a greenhouse. Around 90% of people who purchase pre-made polytunnels choose to erect them themselves, because it’s incredibly simple to do, and can save a significant chunk of cash compared to hiring a handyman or builder to do it for you. So here’s an easy guide to walk you through the process of building your very own polytunnel.

What Is a Polytunnel?

Basically speaking a polytunnel is constructed from a metal-framed semi-circular tunnel covered in hardwearing polythene with UV inhibitors to maximize its lifetime. A large amount of air is enclosed by a polytunnel, so it stays warm much longer than a greenhouse – and also does not suffer from such dramatic temperature fluctuations in summer. During the winter you can regulate temperature and maintain heat very simply by lining the inside of the tunnel with bubble wrap and then removing it in spring. The polythene film has a lifespan of between five and ten years, but the cost to replace it will be only 15%-20% of the cost of the original tunnel.
