How Much Do Polytunnels Cost?

If you are thinking about buying a polytunnel for your garden, it’s important to understand how much they cost. Prices will vary depending on the size of your polytunnel and if you want it to be custom-built. You can also purchase pre-made polytunnels and have them delivered to your home. If you have some basic construction skills, you can build a polytunnel on your own. If you are not good at this, you can also purchase a frame and cover and have it delivered. This is a very convenient way to get a polytunnel for a cheap price.

Price range

There are several price ranges for polytunnels, from fifty dollars up to several thousand dollars. The cost depends on the size and type, and the quality of materials used to build the structure. Polytunnels should be durable and long-lasting, and you should not choose a cheap model if you plan to use it only a few years.

Polytunnels are self-contained gardens that are made to withstand extreme weather conditions. They provide protection for plants against pests, allowing for faster plant growth. In addition, the polytunnels can double as vertical gardens, making indoor farming easier than ever.


Polytunnels come in a variety of sizes. While the standard length of polytunnels is 14 or 18 feet, you can get one of a smaller size if you’re working with a limited budget. You will likely have to purchase one that can last several years and has sufficient structural support.

The smallest size can be assembled fairly easily, although it might take you a bit more time and effort. Also, smaller polytunnels may come with poles or metallic pins for securing the structure to the ground.

Greenhouse effect

The Greenhouse effect is the term used to describe the greenhouse effect of covered structures. These structures include polytunnels and greenhouses. They can cover large areas. Alternatively, they can be cloches, which are covered with plastic. The purpose of a greenhouse is to increase the amount of sunlight that plants receive. Some greenhouses also use supplemental lighting to create a spectrum of radiation that matches the plant’s photosynthesis.

Polytunnels have the same effect as respiration chambers, but are much simpler to operate. They can be used to measure methane emissions from single animals or small groups of animals, and they have the advantage of allowing animals to express their normal grazing behavior. In the UK, researchers have successfully used polytunnels to measure the methane emissions of ruminants in semi-natural grazing conditions. These structures are made of heavy duty polyethylene with large diameter ports.


There are many advantages to using polytunnels in your garden. Not only do they increase your growing season by up to six weeks, but they can also protect your plants from weather conditions that would damage their health otherwise. Polytunnels can protect your plants from extreme heat and bright sunlight, and they can also protect your crops from hailstones and winds. Many market gardeners use polytunnels to extend their growing season and avoid having to cut back on their crop production during the winter. In addition to this, polytunnels are also ideal for seedlings and young plants, and they can be used to start seeds.

When it comes to polytunnels, you should invest in a high-quality, British-made model. These units are built to strict industry standards, and they are made from quality materials. Don’t buy cheap imported polytunnels, as they are often not reliable and don’t provide adequate protection for your plants.


Ventilation is a crucial aspect of polytunnel gardening. Polytunnels should have maximum ventilation during the day and should be closed up in the evenings to maintain a consistent temperature. Large differences in day and night temperatures can cause problems, particularly for plants like tomatoes. Using a thermometer to record the temperature in the polytunnel will help you determine the best settings for the time of day.

A side ventilation system provides good air movement within the polytunnel. These systems are available as complete kits and include a timber or aluminium fixing rail with side aluminium gutters. The roll-up curtain is held in place by wide mesh netting.


The durability of polytunnels is an important factor in crop production. It depends on the quality of the frame and polythene. Generally, polytunnels should be replaced every five to ten years. They help farmers control the growth of their crops, and they help them to manage soil and nutrients. They also help prevent the damage caused by pests. In addition, polytunnels can help grow crops all year round, allowing farmers to keep costs down and make their businesses more sustainable.

Although polytunnels are generally sturdy and durable, they are subject to damage and need to be repaired. To prevent damage to the cover, it is important to choose a durable one made of 720-gauge material (equivalent to 180 microns). Generally, these polytunnels last for at least five years, but they can last for as long as ten years.
