Which Is Better – A Polytunnel Or a Greenhouse?

Which Is Better Polytunnel Or Greenhouse

You may be asking which is better: a Greenhouse or a Polytunnel? Well, the answer to that question depends on your circumstances. A good quality greenhouse will last for many years, while a polytunnel will last for about 15 years under the same conditions. However, you will need to change the covering of the polytunnel after five years.


If you’re looking for a low-cost way to cover your garden or grow vegetables, you might want to consider buying a polytunnel. These are cheaper than greenhouses and can cover larger planting areas than a conventional greenhouse. For example, a basic 2.5m x 2m polytunnel will cost you around PS50 delivered, which is about the same as an eight-foot-by-six-foot greenhouse. This will give you a good deal of coverage and will keep the plants protected from weather elements. A good-quality polytunnel will last for at least 15 years in the same conditions, though you’ll need to replace its cover every five years.

A polytunnel is a smaller structure than a greenhouse, and their sizes vary depending on the manufacturer. They are often heated by sun or artificial heat, and have adequate ventilation. Some are automated, but many are manual. Some also have openings on the sides, or you can use electric fans to circulate the air inside.


When deciding between a polytunnel and greenhouse, you need to consider how much space you want to cover. In general, a polytunnel is much cheaper than a greenhouse and requires less investment. A polytunnel is also much easier to move around and requires little preparation before installation. However, it is important to remember that it requires replacement polythene every seven to ten years.

The cost of a polytunnel can be significantly lower than a greenhouse, which is about three to four times as expensive. You can buy a 6ft x 16ft polytunnel for around $600, compared to over $2,200 for a greenhouse of the same size. A polytunnel has several features, such as UV protection, anti-fog and thermal coverings. They also come in a variety of colours and materials. The most common thickness is 720 gauge, which is 180 microns thick.

They are cheaper

There are many benefits of using a polytunnel or greenhouse for your garden. They can be a great option for home gardening, as they are much cheaper than traditional greenhouses. They can also be placed in a sloped garden and require no ground preparation.

A polytunnel is typically made of polythene, which makes it surprisingly durable and strong. It is designed to withstand harsh weather conditions, making it the ideal solution for both professional and hobby gardeners. It is also useful for storing machinery and other expensive equipment, because it protects them from damage.

They are easier to assemble

When building your polytunnel or greenhouse, you must take care to follow certain guidelines. Make sure you check your local council regulations. Using a suitable tool for the job will help you assemble your structure safely and efficiently. It is also recommended to contact your local council office if you have any questions.

Polytunnels are available in different sizes. These can range from 16 to 30 feet, or 30 to 90 feet. They are also available in different heights. Ensure that you plan the layout well to provide proper air circulation for your crops. It is also advisable to select heavier-weight plastic if your location has a strong wind.

They retain more heat in the summer

The domed shape of a polytunnel or greenhouse keeps the interior temperature higher than the outside. During the summer, the temperature will remain more comfortable, ensuring the growth of plants. A polytunnel or greenhouse can be used for seedling plants, germination of seeds, or crops that need heat to grow.

The optimum temperature for plants is between 16 and 35 degrees Celsius. However, temperatures can rise well above this mark, causing stress on plants. This can lead to increased disease and pest problems. Another issue is weeds, which can outcompete and harbor pests. Most polytunnel and greenhouse crops require a certain temperature range and will be harmed if it exceeds this limit.

They are better for herbs

If you want to grow herbs in a climate-controlled environment, a polytunnel or greenhouse may be better. Unlike a traditional greenhouse, a polytunnel is easily expandable and can be built on a smaller area than a greenhouse. The downside to polytunnels is that they need to be kept dry and have high humidity, so they aren’t suitable for a rainwater collection system. However, polytunnels are cheaper to purchase and extend.

There are many factors to consider before buying a polytunnel or greenhouse. You want to make sure you choose the best one for your needs. Firstly, choose your budget. You should be able to find a greenhouse in your price range, but don’t be tempted to go overboard.
