Garden Grow Polytunnel 3M x2M Powder Coated Steel Frame, Walk In Greenhouse, Double Zipped Door & Windows (3 x 2 Polytunnel)

Product Information

It features double stitched seams for maximum durability and has a double zip door that can be rolled up for easy access. There are also netted windows to ensure the temperature within the greenhouse can be controlled. These windows can also be covered by rolling down the PE covers.

All in all, it does take time (we spent 2-3 days on ours), especially if like us, you like to read and then re-read all the instructions and watch and re-watch all the videos! It also does need some level of physical effort, though it’s more about stamina than strength. Durable, heavy duty PE cover to protect your plants is 100% waterproof, windproof and protects against harmful UV rays. Protecting your plants all year round. Steel Frame – robust metal frame is built to last with a powder coated finish for added durability. If you want to overwinter slightly tender plants, your space needs will be smaller than if you want to extend your growing season, grow summer crops such as tomatoes or grow more exotic plants. And once a plant has been infected, there is, most of the time, no cure. All you can do is remove the infected plant.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. You could also consider growing a hedge to break the wind, if the wind tends to come from one direction. The best polytunnels for an allotment or garden will be extendable polytunnels. This means that you can add more space if you need to. I would recommend doing this at the same time your cover needs replacing though, as this will prevent you from wasting money. choice of foundation to suit your allotment: foundation tubes, anchor plates, screw anchors, base plates for timber, base plates for concrete

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. This specialist structure is designed to help create the ideal environment for your plants, flowers and vegetables to thrive. 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 Another consideration you should take into account is whether you are planning to heat your polytunnel or not.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). So it is important to buy the best quality you can for your budget. To ensure you get the best polytunnel for your needs, look out for these criteria.

First you have to decide what size polytunnel you need. This will depend on what you will use your allotment polytunnel for and what space you have available. When choosing a polytunnel, there are some things to consider. After all, you don’t want to spend money, time and effort and then not get what you wanted. A well ventilated polytunnel will keep moisture levels in control, but also ensure the polytunnel does not get too hot.If your budget won’t stretch to a cover that has these special features, then the next point is even more important, ventilation. Ventilation When you buy a polytunnel, you don’t want to have to replace it after a season because it is of poor quality. Six Windows – the insect-proof mesh windows keep pests away, while the roll-up cover creates a welcome air flow throughout the tunnel. When closed, the greenhouse maintains higher humidity levels – ideal for growing tropical plants. We went for extra support braces, sliding doors, crop bars, and staging to give us more growing options and increase the stability of our tunnel. There’s an explanation of what each option provides (some even have short videos to explain!) and the graphic on the left changes to give you a visual representation. 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.

HEAVY DUTY POLYTUNNEL COVER: As well as superior framework our covers are 140gsm and the UPVC cover will let ample UV light in whilst also being expected to last a number of season in the British climate. There is ample skirt material around the bottom of the polytunnel cover to be dug into the ground for additional stability. My recommendation would be to sit down and think carefully about what you want to grow on your allotment or in your garden. Inside the polytunnel but also outside. While the First Tunnels polytunnel is not the cheapest, it is well worth the money. You will get the polytunnel that suits your allotment and your growing needs. A Fully Galvanised Structure with added internal bracing...more so than any other in it's class. This tunnel not only has Three arches and a " Ground Bar Kit", we have also added Two opposing corner diagonal brace bars and a central roof horizontal brace bar, thus giving greater flex tolerance against wind stresses, a front hinged double skinned metal door with closing catch and, rear zippered roll up door suitable for barrow access - completes the structure. A heavy 150g/sm crossweave, rip stop cover with four netted window vents, two on each side and a wide ground skirt for entrenchment gives increased protection against the elements. 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.

The next thing to consider is the location of the polytunnel. Will it be sheltered and protected from the elements or will it get battered by wind and rain. 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.
