Which Is Better Polytunnel Or Greenhouse?

Which Is Better Polytunnel Or Greenhouse

A polytunnel is a greenhouse that can be built against a garden wall or the exterior of your home. It is designed for seedlings or potted plants. Some greenhouses require professional installation, but polytunnels are designed to be erected by two people in a single day.


Polytunnels can be an excellent option for those who wish to grow plants in an outdoor environment. They can be erected on rough ground without damaging the garden and are considerably more flexible than greenhouses. Generally, greenhouses can last as long as fifteen years in the same conditions, while polytunnels will only require replacing the cover every five years or so.

Polytunnels are usually used in temperate climates and are similar to greenhouses and cloches. Modern polytunnels can be equipped with sowing machines and harvesting equipment, allowing farmers to increase their productivity. They have had a significant impact on the growth of strawberries in the UK, while they are also suitable for soft fruits and vegetables. In addition, polytunnels can be fitted with foggers that reduce the temperature without increasing humidity.


Greenhouses and polytunnels both have their advantages and disadvantages. A greenhouse requires more time to build and requires a level site to be levelled off, whereas a polytunnel can be installed on rough ground. A greenhouse also requires an expensive investment in glass and the larger sizes can cost several thousands of pounds.

A polytunnel is much less expensive than a greenhouse, and requires a lot less site preparation. A good quality polytunnel can last for about 15 years under the same conditions. However, the covering will need replacing every five to eight years. A polytunnel is less expensive to heat than a greenhouse. However, it is necessary to keep in mind that the cost of heating a greenhouse will increase as it becomes larger.

Greenhouses are much more expensive than polytunnels, which can be up to three to four times cheaper for a similar size. For example, a six foot by 16 foot polytunnel costs around $600, whereas a six foot by 16 foot greenhouse can cost around $2,200. A polytunnel’s covering can be UV and thermal, and it can be made in any colour. The most common thickness is 720 gauge, which is 180 microns thick.


When deciding which type of greenhouse to build, it is important to consider the ventilation options. A polytunnel typically has a single door at each end, while a glasshouse may feature louvre vents or automatic opening mechanisms. Glasshouses don’t need electricity and are available in a range of attractive designs. They are also often situated near a house for added aesthetics.

Another difference between a polytunnel and a glasshouse is the space. Polytunnels are larger and can protect a larger area than glasshouses. They can also be modified to accommodate machinery and sloping ground.

They serve the same purpose

Although a greenhouse and polytunnel are both used for growing plants, a polytunnel is more cost-effective and can be moved. However, both serve the same purpose, so you may choose whichever is best for you and your gardening needs. The best polytunnel is one that is easy to access and has a sunny location. It should also be level and protected from wind. Moreover, a good soil and water supply are essential for growing the plants that you want.

A polytunnel is much easier to install, whereas a greenhouse can take several days. It is also cheaper, and is better suited to large-scale crops. However, a polytunnel has some disadvantages, including condensation issues and problems with light transmission.

They are more durable

Greenhouses and polytunnels are both durable structures, but greenhouses tend to handle harsher weather better. While polytunnels are easily damaged by storms, greenhouses are more resilient and last for decades. They also require less maintenance and are easier to assemble. In addition, polytunnels can be set up on uneven ground, while greenhouses need to be built on firm foundations and can take longer to install.

While polytunnels and greenhouses are both durable and weather-resistant, they do need regular repairs to keep them looking their best. It is recommended to replace polytunnel covers every few years, depending on their location. Trimming foliage and cleaning windows and floors can help extend the life of a polytunnel or greenhouse. Ladybugs can also be used to control pests.
