Are Polytunnels Any Good

Less expensive than greenhouses

In addition to being less expensive, polytunnels can be more flexible in terms of where they can be built. Unlike greenhouses, which need a flat base, polytunnels can be built on slopes or uneven ground. They are also much easier to erect, and can be set up just about anywhere.

However, polytunnels are not without their disadvantages. The main one is that they require good ventilation. Ideally, they should have doors on two sides. This is because a through draft is essential for healthy crops. In addition, polytunnels are poor at keeping heat in, so condensation is a problem. However, specialist plastic with anti-fog properties can help reduce this problem. Also, assembling polytunnels is much quicker than building greenhouses.


If you are planning to use a polytunnel to grow plants, you should invest in a durable one. The plastic that covers the frame is the most vulnerable part to the elements, so you should opt for a tear-proof and waterproof one. In addition, the polytunnel should have fully sealed doors and windows.

Durable polytunnels are made from quality materials and will last for many years. These are ideal for growing a variety of plants. Moreover, they include a ventilation system, which will help you control the climate inside the polytunnel.


Polytunnels have a lot of benefits and can be a useful addition to any garden. They can provide growing space, extra storage, and weatherproofing. There are many different types available, so you can choose a type that suits your specific needs. If you’re unsure about what kind to buy, there are a few ways to ensure you get the best value. The first tip is to take measurements of your outdoor space. Then, choose a model that fits the space available.

Another thing to consider when choosing a polytunnel is the material. Make sure that the material is durable and has good tear and water resistance. The polythene covers should also be tear and wind-proof, and the doors and frames should be fully-sealed.


If you want to grow a crop year round without the worry of pests and disease, you should consider investing in a polytunnel. These structures are very similar to greenhouses and cloches, but they are more modern and are equipped to house sowing and harvesting machines. For instance, they have made a major impact on the production of strawberries in the UK. However, they can also be used to grow soft fruits and vegetables. You can control the temperature inside them by using foggers. This prevents humidity from increasing and helps you maintain a comfortable climate for plants.

When you buy a polytunnel, you must ensure that you choose a reputable manufacturer. While buying a cheap polytunnel is tempting, you may not get good quality for your money. The materials used to make these structures should be durable and strong.

Easy to erect

You don’t have to be an engineer to construct polytunnels. Just take your time and follow the instructions carefully. If you don’t understand anything, you can always consult a guide to help you. A guide will help you avoid mistakes and make the whole process easier.

Firstly, you need to erect the frame. This should be based on the instructions provided by the manufacturer. Once this is complete, you need to attach the covering. It is recommended to do this on a day without wind.

Suitable for growing edible plants

To have a successful edible garden, make sure you select the right soil for the type of plants you want to grow. Ideally, the pH level of your soil should be between six and seven. If it is too acidic, you should add calcium to the soil, while an alkaline soil can benefit from the addition of compost and sulphur. You should also consider seasonality when selecting plants to grow. Suitable edible plants include lemon trees, apricots, bay trees, and a variety of berries.

If you have a sunny window, you can grow an edible garden indoors. However, if you live in a house with shady windows, it may not be the best place to grow edible plants. Likewise, windows that face the north can be too cold for edible plants. In addition, you should check whether the glass on your windows is tinted or transparent to allow sunlight to reach the plants.
