Are Polytunnels Worth It?

Are Polytunnels Worth It

You might be wondering if investing in polytunnels is worth it. There are several factors to consider, including size, location, and cost. However, you should also consider the environmental cost. The initial investment is surpassed by the benefits in the long run. You will find that the money spent is well worth the returns.


While polytunnels are expensive, the benefits outweigh the initial cost. If you want to grow vegetables and produce crops year round, polytunnels are a great option. They allow you to grow many varieties of plants that you would not grow outside. You can control the humidity and overheating by keeping the structure properly ventilated.

Polytunnels are popular in the U.S. and England for growing early crops. They are ideal for growing tomatoes, peppers, squash, and zucchini varieties. The production time is usually two or three weeks faster than in a local field. These produce often sell for higher prices due to the high demand for fresh produce.

The cost of polytunnels depends on the size and quality of the structure. For instance, smaller polytunnels may be easier to assemble, but they will require more time and effort to build. They may also come with poles or metallic pins to secure them to the ground.


When buying a polytunnel, you should make sure you choose one that’s the right size for your space. It’s also important to consider the size of your budget, and how many children you’ll have. Then, choose a material that will last a long time. The main components of a polytunnel are a strong frame and bracing, as well as polythene covers.

The size of polytunnels will vary, depending on your needs and wants. For example, if you want to produce food, you’ll need a larger space. If you’re planning to grow a variety of plants, a smaller polytunnel will probably not be enough.


It is important to choose the right location for your polytunnels. You want to place them where there is enough sunlight to grow the plants you want. It’s also important to keep them away from buildings and trees. A polytunnel should also be placed in a location that doesn’t experience too much wind. In addition, you’ll want to make sure that the soil is good and not too dry.

In the UK, polytunnels are commonly used for livestock housing. Although polytunnels are expensive, the revenue from the crops they grow will often justify the cost. For this reason, these structures are becoming increasingly popular in our countryside.

Ecological cost

The ecological cost of polytunnels is often calculated by considering the carbon footprint of the materials used to construct them. This includes the carbon released from the production and transportation of the metal frame. For example, for every 1kg of steel produced, 1.83kg of CO2 is released into the atmosphere. This carbon cost can also be calculated for the transportation of the polytunnel. For the entire lifetime of the polytunnel, the environmental cost of a polytunnel is usually better than the carbon neutrality of the product.

Another important factor to consider is the climate. Polytunnels can become warmer than the temperature outside, making it crucial to maintain proper ventilation. However, with proper ventilation, you can control the amount of overheating and humidity. With regular ventilation, you can keep the climate at a comfortable level for your crops. The use of different polythene will also help control the humidity and temperature.


Polytunnels are an excellent way to grow your produce in a controlled environment. They allow you to maximize the use of space in your garden and produce all kinds of crops all year round. They are also a great way to grow organic food. They are made from galvanised steel and feature a solarweave shade cover that helps to maintain the ideal temperature, humidity, water and carbon dioxide levels.

Aphids are among the most common pests in polytunnels and can become a serious problem if not controlled. Aphids are attracted to plant parts in poor health, so the key to controlling their population is to keep your plants healthy. Healthy plants get plenty of water and nutrients and are less susceptible to disease or pests.
