If you know that it will have to withstand strong winds, you also want to make sure that you secure it as much as possible. This includes strengthening its structure by adding crop bars and storm bracing.

Also Protects Against The Warmth That Builds Up On The Steel Frame All through The Summer Months Causing Warmth Degradation. In this review we will touch on the ease at which the tunnel is constructed, as well as the ease of use in general, in terms of transportability, added features and room for movement inside the tunnel but some main pointers that serve all polytunnels:

We have polytunnels available in sizes from 6ft up to 30ft wide, catering for both those seeking a small polytunnel and professional producers searching for something that suits their commercial growing needs. Each polytunnel for sale is available with free delivery to most of the UK. Our products are made to the highest quality from durable materials such as galvanised steel for the framework and pressure-treated timber for doors and base rails, ensuring they retain their strength and shape even in adverse weather conditions. But you also want a polytunnel that can be fixed securely in the ground. This can be done in several ways, such as ground tubes and ground anchors, fixing plates or trenching (where a trench is dug around the polytunnel and the polythene cover is buried to keep it in place). Bolts are normally 8 to 12mm and an impact driver makes this a breeze as well as can really secure the bolts I would always recommend buying the best quality for the price you can afford, even if that means shopping around a bit. The video should serve as a prudent reminder buying is half the job or less, the other half is having this thing really deep rooted into the ground so here’s some tips to make sure yours doesn’t blow away: Anchor your polytunnel properlyThe short answer is yes. We have briefly talked about ventilation earlier, but let’s go into more detail. I like the zips and ties to hold your doors. It’s a pretty hard ask – to get much more for your money, this things less than a decent lunch and a bottle of wine. To start our review off, we will take a look at the Outsunny polytunnel, the smallest and consequently cheapest product on our list. Unlike the products which we will later go on to look at, the Outsunny polytunnel boasts a wide and low design – so low that you can’t actually get inside the tunnel, which is exactly why it ranks at the bottom of our list. However, don’t be discouraged – this does not have to be a dealbreaker, it is simply a unique design feature of the product which will put some users off, but will likewise draw others in. It measures a whopping 2 metres in height, 3 metres in length and 2 metres in width, making it a monster of a garden accessory, big enough to house a jungle of plants. Whilst the polytunnel is certainly big from the outside, it is the inside space which is of a higher importance, something you certainly won’t have to worry about with the VonHaus polytunnel which has an impressive floor size of 6 metres squared. Wow. After the construction was complete, we finished ours off with some cheap pallet collars (bought from Facebook Marketplace) as raised beds, then laid a slab path down the middle, filling in the gaps with gravel.

The way it works is that you buy additional arches and a bigger cover. This is a good solution if you are not sure about the size you need, as it gives you the option to make it bigger, should you need to. Location For the largest two polytunnels in the commercial collection – the 27ftand the 30ft wide– timber base rails are supplied to secure the cover and a triple ridge kit is included for additional strength. Optional extras Finally, we have come to budget. Hardly any of us are able to just buy the best polytunnel out there, money no object. Most of us are limited by a budget, we can’t buy an expensive polytunnel, even if we wanted to. If you do not have purpose-built housing you could use a garden shed or polytunnel, as long as there is adequate light, space and ventilation.’ Another problem that can occur in a polytunnel is moister build up. Condensation can create the perfect environment for fungal diseases, which love damp, warm conditions.Having a door you can open, to let much needed air into the polytunnel is vital. Two doors, one at each end, is even better. Because this will allow you to achieve air circulation.

Like the VonHaus polytunnel, the frame is constructed from four galvanised steel hoops, which support a strong, reinforced plastic cover. One key difference between the VonHaus polytunnel and the VOUNOT polytunnel is the door. Where VonHaus have included a swinging door, fit with a metal frame, VOUNOT keep it simple with a roll-up door which is secured shut with a zip. I do think that the VonHaus swinging door is a nice feature, however it is somewhat pointless, and given the extra effort the door takes in assembly, as well as the premium in price which you pay for this extra, I think VOUNOT have got the right idea in keeping things nice and simple with a roll-up plastic door.So how is this beast constructed? Good question. The frame comes in four huge hoops with one swinging door at the front of the tunnel. The frame is made from a rust-resistant tubular steel, powder coated to enhance the frame’s overall strength and extend its lifespan. Unlike the other polytunnels we have looked at so far in this review, the VonHaus polytunnel frame is connected by screws and bolts and not plastic attachments. This feature works hard to reassure me of the sturdiness of the polytunnel, however it does of course make constructing the product that little bit harder. Despite saying this, with all of the assembly parts included, in addition to clear instructions to help the user, the assembly of this product is surprisingly easier than you would expect – plus once you’re done assembling the tent you will have a structure the size of a shed, so the assembly process is bound to be a little longer than that of VonHaus’ smaller counterpart polytunnel. Perfect to keep young plants protected during harsher conditions, this polytunnel is supplied with high-quality, durable, metal pegs to ensure it’s always secure to the ground. If you decide that your crops are ready to face the weather alone, simply move the lightweight tunnel to your next crop or deconstruct with ease for use again next season. You could also consider growing a hedge to break the wind, if the wind tends to come from one direction. To be able to use the trenching method, the cover needs to be big enough, so look out for any mention that the polytunnel is suitable for this method. From years of experience though I prefer to use 22mm pipe cover. This can be installed after you have the cover on – a massive advantage over hot spot tape if you are doing this retrospectively: Using pipe cover is far more effective than hot spot tape as it can be done retrospectively and is cheap too Assembly and Ease of Use

PLANT PRIORITY: A strip window runs down one side and is fitted with mesh to keep bugs out whilst allowing ventilation, a clever feature allows the plastic flap to be clipped up creating a water catcher which funnels water to the end allowing you to place a water butt under it. If you want you can re-stitch that, I just don’t think the aesthetics is anything to worry about at all and so duct tape is the solution. The real solution after that though is hot spot tape. What is hot spot tape? Basically it’s a foam tape that reduces the stress between the metal pole and canvas. The softer edge means when the window blows it’s much less likely to become a problem with damaged corners – and that’s where it always starts.

One thing I wouldn’t recommend is going for the cheapest options. Because these tend to be of poor quality and are likely to only last for a few months. You want to make sure your polytunnel has a metal frame. The best polytunnels for an allotment or garden will have a frame made of galvanised steel, which is a very strong material. choice of foundation to suit your allotment: foundation tubes, anchor plates, screw anchors, base plates for timber, base plates for concrete There area few key factors in ensuring your polytunnel stays still, even in a serious gale there shouldn’t be much reason to fear, though if you’ve already got one you do question at home, I hope the polytunnel is holding up 😀 – still, let’s look at how to fix one in properly and make sure it never blows away – and if it does, your neighbouring polytunnels went long before yours! So here’s some tips to hold polytunnel down here: These handy tips are more than enough to see you through a simply install but a further bonus is to have a cordless drill and impact driver with the correct size hexagonal bit for the nut – normally 8-12mm that I’ve seen in my experience assembling these kits. Space – height not just surface area is key
