Advantages And Disadvantages Of Polytunnels

Having a Polytunnel can be a very helpful tool for growing your crops. It has several benefits to it, including improved air circulation, better germination, and attracting bees. However, you also have to think about the disadvantages of having one. Listed below are some of the common ones.

Improved air circulation

Investing in a polytunnel can help your crops survive a heat wave. Heatwave temperatures can be devastating for crops, and they can also increase the risk of disease.

Polytunnels provide heat and humidity that is controlled so that your plants are healthy. They can also be used to grow crops that are not generally available in outside climates.

Polytunnels can be purchased or constructed from scratch. They can also be modified to meet specific needs.

Polytunnels are a cheaper option than greenhouses. They are generally more flexible, and can be widened to provide more interior space. They are also used for plant nurseries and livestock housing.

Polytunnels can also be used to grow crops before and after the growing season. They can also help protect crops from intense heat, cold waves, and hailstones.

Attract bees

Keeping bees in your polytunnel may not be on your list of priorities, but they can be a lot of fun and it will definitely benefit your crops. In fact, keeping a few hives can help pollinate your tomato crops.

The best way to attract bees is to provide them with access to your crops when they are in bloom. This can be done by providing plants in different heights. Providing a wide variety of plants will also help provide a plethora of nesting material and food sources.

Providing a well-designed polytunnel can do wonders for pollinators. The design should be built for both protection and ventilation. When possible, open the doors to the polytunnel so that the bees can fly in and out. Also, keep the roof vents open so that the bees can leave and the ventilation is better.

Better germination

Whether you have a large or small garden, polytunnels can help you maximise your production. They are easy to set up and provide a better growing environment. They can also prolong the season.

A polytunnel is a structure that can be used to grow fruit and vegetables during the summer and winter. This is especially useful for vegetables such as squash. These types of crops need a longer summer season.

Polytunnels are usually made of two layers of polythene. These are often reinforced with nylon mesh. This helps to make them more resistant.

Polytunnels are a great way to grow many different kinds of plants that would normally be out of reach in the outdoors. They can extend the season for your crops and make them grow faster. They are also affordable for all types of gardeners.


Whether you are growing fruits and vegetables or simply looking for an outdoor storage space, polytunnels are an effective way to extend your growing season. They can also help you protect your crops from a range of factors such as hailstones and intense heat. In addition, they can help you recycle waste to increase yields.

To calculate the ecological cost of polytunnels, you need to consider both the carbon cost of transporting the cover to your site and the carbon cost of manufacturing the cover. The average CO2 emission factor for road transport in Europe is 62g CO2/tonne-km.

The average CO2 emission factor for rail freight is 22g CO2/tonne-km. A polytunnel that has a metal frame will have higher carbon emissions than a polythene cover.


Getting a polytunnel for your garden is a great way to protect your crops from pests and extreme weather conditions. They are also a great way to extend your growing season.

There are a number of factors that play a role in the cost of polytunnels. One is the carbon emissions that occur during manufacture. The carbon emissions are also attributed to the transportation of the polytunnel to the site.

If you want to keep the carbon emissions down, you can get a polytunnel made of metal instead of plastic. The carbon emissions are higher for the metal structure, but it is affordable.

Depending on the size of the polytunnel, the cost ranges from around $50 to around $1000. You can also buy cheaper polytunnels online. These are usually of poor quality and won’t last very long.
