Poly Tunnel for an Allotment FAQ
Is a poly tunnel better than a greenhouse?
Polytunnels and greenhouses work in similar ways, both designed to boost your harvest and protect plants from bugs and birds.
The advantages of a polytunnel are that they are much cheaper to buy and great value for money. They can be built onto a soil base and they’re very easy to assemble. Polytunnels can be stored easily, moved around the garden and are simple to disassemble. Plus, their steel frame should last for years.
Greenhouses on the other hand are much more expensive and very time consuming to put up. They’re usually made from glass or polycarbonate plastic which makes them heavy. While greenhouses can look great, they aren’t the best option if you lack garden space and the ground they are built on must be hard and level. They will however, last longer than polytunnels.
How do polytunnels work?
Polytunnels provide protection to plants and can let you continue growing weeks after the season’s end. The material used to build them allows the interior to heat up from the sun. The warm air and humidity is contained, creating a microclimate which allows plants to grow – including those that wouldn’t naturally grow in the UK!
Polytunnels also protect your plants from bugs, birds and animals; usually with mesh windows that allow for ventilation without letting pests in.
How long does a poly tunnel last?
Polytunnels are usually made up of a steel frame and polythene covering. While greenhouses should last a lifetime, polytunnels have a slightly shorter lifespan – although buying from a quality manufacturer should mean it lasts longer.
Generally a polytunnel frame should last for 20 years plus, while the polythene cover may need replacing every 5-10 years. Investing in a durable, high quality polytunnel will save you money in repairs, and it’s important to clean your polytunnel in the winter months.
Allow your plants to thrive season after season with a quality polytunnel. The Parviflore Allotment Poly Tunnel is our winner, thanks to the ultra solid structure, interior space and great ventilation. Perfect for large allotments.
