What To Look For When Buying A Polytunnel

If you are planning on purchasing a polytunnel for your home garden, you need to know what to look for. Here are a few important points to consider: Cost, Size, Ventilation, and Quality. A good quality polytunnel will be durable, yet still allow enough light to reach the crops inside.

Cost

A polytunnel is an excellent way to grow a variety of crops. It is also very easy to maintain and you can easily alter the structure as you see fit. This structure is also a great way to grow herbs. However, you should be aware of the cost, as a polytunnel is a significant investment.

There are two types of polytunnel: those made from plastic and those made from metal. The former has a higher carbon footprint than the latter, but this is largely due to the weight of the structure. If you can source your polytunnel locally, you can keep the carbon footprint to a minimum.

Size

The size of a polytunnel is a crucial factor when planning to build one. It will depend on your growing needs and your budget. It is best to choose a smaller tunnel if you have young children. A polytunnel is an investment, so you should consider a sturdy and long-lasting one. It consists of a framework of bracing and hoops, and the cover is usually polythene.

A polytunnel should be large enough for the area of your garden. It should be heated by the sun and/or by a greenhouse heater. The structure should also have windows and doors for air circulation.

Quality

When choosing a polytunnel, it’s important to look at its quality. While you don’t need to spend hundreds of pounds on a polytunnel, it is important to choose a quality one. It should be durable and strong. The size should also fit the amount of space you have in your garden.

Look for a polytunnel with a good quality polythene cover. Cheap ones will split easily. The better ones have a five-year guarantee, and are expected to last around eight years. If a cover splits or tears, you should be able to replace it. Small tears can be temporarily repaired with tape, but it is important to buy a replacement as soon as possible.

Another important factor when choosing a polytunnel is its frame. A strong polytunnel frame will keep it stable and protect your crops from the elements. The type of material used for the frame will determine the structure’s durability and insulation. A steel frame will be more sturdy and resist corrosion. However, a cheaper steel frame will be thinner and more fragile. Depending on the weather conditions in your area, a steel frame may not be suitable for your situation.

Ventilation

When buying a polytunnel, one of the most important factors to consider is ventilation. You will need to decide whether the polytunnel you are considering has doors or not. If the polytunnel has no doors, you will need to consider side ventilation. Alternatively, you may use a polythene blind on the outside of the polytunnel.

Proper ventilation is important for both plant health and for the health of livestock in a polytunnel. Proper ventilation can help control temperature and humidity inside the polytunnel and helps prevent common plant diseases. Ventilation can be achieved in a number of ways, including using ventilation fans or doors.

Direction of wind

The direction of wind is a crucial factor when choosing a site for your polytunnel. In the UK, the wind tends to blow from the south-west, but the exact direction of wind depends on topographical and geographical factors. It is therefore important to spend some time studying your site before making a decision. Find out what the wind is likely to be like during different times of the year, and get in touch with neighbours if you can.

A polytunnel will need to be secured in the ground by erecting the tubes in advance of the door frames. It is also important to get some help when putting up the door frames and covering the polytunnel.
