Best Polytunnel For Allotments and Gardens – Buying Guide

Similar to a greenhouse a polytunnel is great for allowing gardeners to grow certain fruits and vegetables that might not otherwise be possible due to the cold harsh climate we have here in the UK. Polytunnels are very good at protecting crops from strong winds, heavy rain and to an extent frost. With these benefits it’s no wonder they are becoming increasingly common in both gardens and allotments up and down the country.

If you are thinking of purchasing a polytunnel for your garden or are just taking a look at the options currently available then our guide is just what you have been looking for. From the different types and what to look out for when buying one to the best polytunnels on sale in the UK, we have you covered.

But first,

What Is A Polytunnel

A polytunnel is a structure that is made of steel tubing and has a polythene cover to protect whatever it is you are cultivating from the worst of the weather. Similar to a tent in design but with the functionality of a greenhouse their main purpose is to increase your growing season and allow you to grow a wide variety plants, herbs, fruit and vegetables.

The semi-circular design of a polytunnel is the reason you might hear some people call them hoop houses. It is worth mentioning that there are now models available with a straight side as opposed to the traditional semi-circular design. This more modern design increases the working height right up to the sides of the polytunnel and makes weeding a less strenuous task.

How To Choose The Best Polytunnel

Now that you have decided you want to buy a polytunnel its best to learn a bit of information about them before you part with any money and choose a particular model. There are a number of things to consider first that will help you to find the one that best suits your overall needs.

Size and Location

Where you are going to place your polytunnel and the overall size of the one you are going to need are the first things to think about before buying. Polytunnels come in a wide range of sizes and unlike a greenhouse you can install them on a slight slope giving you some leway when choosing your location. The most popular size for gardens tends to be the 3m x 2m x 2m which gives ample room for growing many different varieties of fruit and vegetables or just lots of one if that’s your thing.

Installation

Installing a small polytunnel can be completed by most people in a couple of hours. Obviously large polytunnels do take quite a bit longer to erect than their smaller counterparts and with the biggest models available a second pair of hands will definitely come in handy.

Ventilation

Similar to a greenhouse a polytunnel is designed to retain heat and keep the warm air in, which can cause problems with humidity especially in the summer months. For optimal plant growth plants need plenty of ventilation. When choosing a polytunnel check that there are plenty of ventilation windows down both sides.

Durable Cover

A durable cover is a must have feature to look out for when purchasing a polytunnel. Things like UV protection and the use of polypropopylene to reinforce the cover are definitely worth keeping an eye out for. It is worth mentioning that polytunnel covers come in either a transparent green colour or are completely transparent.

FeelGoodUK PRO Polytunnel Greenhouse

FeelGoodUK PRO Polytunnel Greenhouse

Our top recommendation for those looking to buy a small polytunnel has to be this one by FeelGoodUK. With built-in features that you won’t find with other brands it has just a little bit more to offer than other similar sized polytunnels. The most noticeable thing about it that separates it from the competition is that it doesn’t have a roll up cover but an actual door that can be opened and closed. This is great for temperature control as well as making it overall more sturdy in design.

Another positive feature and one we really like is that it comes with a rain collector. On each side of this polytunnel there is a fold up flap above the ventilation windows that do a great job of collecting rain water. In addition they stop the surrounding area of your garden polytunnel becoming water logged which is a drawback to models that lack this innovative feature.

Built with heavy duty 25mm steel metal frame and with strong welded joints this is one of the sturdiest options available. With a durable UPVC cover you can be certain that it will stand up to the strong windy conditions that we sometimes suffer from here in the UK.

Garden Point Green Polytunnel Greenhouse

Garden Point Green Polytunnel Greenhouse

Another popular choice for when choosing a polytunnel for the garden are those made by the Garden Point brand. This particular model has dimensions of 3m x 2m x 2m and comes with very good feedback from those that have bought it. In many ways the design and construction is almost identical to the first option in our reviews, except for the lack of a proper door and the rain collection feature that only our top choice has.

Made from 25mm galvanised steel tubing you can be certain that this is another well-built option. It comes with a roll-up zippered door and along the sides there a total of 6 roll-up ventilation windows perfect for creating a microclimate for cultivating your favourite plants, fruits or vegetables.

FoxHunter Polytunnel Greenhouse

FoxHunter Polytunnel Greenhouse

Offering a bit more growing room than the previous models this 4m x 2m x 2m polytunnel by Foxhunter is excellent value for money. However, with the more affordable price tag some sacrifices have been made. Instead of the standard 25mm steel poles that you expect to get with one of the best polytunnels this one comes with 19mm steel poles. These are still up to the job but are obviously not as strong as the more sturdy 25mm.

The cover of this 3 section polytunnel is up to the same standard as the previously featured models, so no qualms there then. Unfortunately there is no built in door with the Foxhunter but there are 2 roll-up zippered doors allowing for plenty of ventilation in the hot summer months. For additional air circulation and controlling temperature there are 3 mesh ventilation windows on each side.
