Is A Polytunnel As Good As A Greenhouse?

Is A Polytunnel As Good As A Greenhouse

Whether you are thinking of having a new greenhouse or a polytunnel, there are some important considerations to think about before making a purchase. In this article, you will learn some things to consider, including insulation, ventilation, cost, and adaptability.

Cost of a polytunnel

Investing in a polytunnel can give you the benefits of a greenhouse, but at a lower cost. These structures can be a useful addition to your garden, allowing you to grow plants all year round.

A polytunnel can be a good option for those looking to grow exotic plants and vegetables. The material used in these structures is surprisingly strong, meaning that it can withstand harsh weather conditions.

They also provide excellent growing conditions for plants. They can also be opened to allow ventilation during particularly hot weather. This will help to prevent heat loss, as well as help plants to survive.

Polytunnels are ideal for growing flowers, especially if they are started from seed. They also allow you to grow a large number of edible plants.


Keeping plants inside a polytunnel warm can be a bit of a challenge, particularly if you live in a cold climate. There are several methods of keeping your crops healthy and alive during the colder months.

The best option is to find a way to retain the heat from your plants. For example, you can build a hot bed using decomposing straw. This is a relatively low cost solution and a great way to keep your plants warm.

You can also build a mini-greenhouse inside your polytunnel. Mini-cloches are also a good way to keep plants warm. This is a good way to protect your precious plants from cold winds and frosty nights. The mini-cloche can be removed during the day, and the cloche itself is fairly portable.

Ventilation options

Keeping a polytunnel cool is an important part of growing vegetables in temperate climates. During summer, it’s particularly important to ventilate the polytunnel. A good ventilation system can keep your plants healthy and prevent diseases.

The location of your tunnel and the type of plants that you grow are both important factors when determining what type of ventilation is necessary. In many British gardens, the combination of natural ventilation and mechanical ventilation is used. In addition to improving air circulation, it helps maintain a consistent climate inside the polytunnel.

If your polytunnel is located in a calm area, it may be possible to close off side ventilation during cooler months. Alternatively, you can affix a shade netting to the roof of the polytunnel on the inside. This enables you to control ventilation and allow rainwater to filter through.

Adaptability to suit livestock housing

Whether you are growing soft fruit or extending your cropping season with polytunnels, they are part of an environmentally sustainable agricultural production strategy. They can also widen your choice of crops and reduce the use of chemicals. However, they also have a detrimental impact on the local landscape.

Large scale developments may cover a large area and can therefore have a cumulative effect. To be considered, a development application must carefully weigh the benefits of polytunnels against the negative impacts.

The planning application process should include an annotated site plan that shows the relationship between the proposed site and the surrounding landscape. It should also show the key characteristics of the site.

When assessing planning applications, the local planning authority should be mindful of the potential impact on local water resources. It should therefore be carefully considered how much runoff will be allowed through the proposed development and whether water use efficiency techniques should be incorporated.

Proper support for a polytunnel

Getting the right support for a polytunnel is important for growing crops. If you don’t do it right, you may damage your polytunnel.

The first thing to do is to decide on the type of plants you will be growing. It is also important to know how high the plants will grow. This will help you determine the amount of space you need for each plant. It is also important to make sure the area you choose is clear of stones and weeds.

Once you have the right type of polytunnel, you can use it for years to come. There are many types of polytunnels available in the market, so you can choose the one that best suits your needs.

You can also make your own DIY plant support. You can use reclaimed wood slats, chicken wire or wire cages. You can also use natural branches from your garden.
