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

Product Information

To prevent the cover coming off in strong winds, you have to either fix it to the frame or use the trenching method, whereby you bury the edges of the cover in the soil. The short answer is yes. We have briefly talked about ventilation earlier, but let’s go into more detail. A well ventilated polytunnel will keep moisture levels in control, but also ensure the polytunnel does not get too hot. Our 3x2m polytunnel will make a suitable alternative to a solid structure to house birds during the Avian Flu outbreak. Our tunnel allows adequate light and ventilation and will help offer protection from wild birds that may be carrying the disease.

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. As already suggested earlier, look for a polytunnel that has a sturdy metal frame made from steel. Some polytunnels are also reinforced by timber, which will make them even stronger and wind reistant. 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.Look out for the ways the polytunnel is fixed on the ground to assess if it will be strong enough for your particular weather conditions. If the location of your garden or allotment polytunnel is especially exposed, you can look into reinforcing your polytunnel with wood, even if the polytunnel itself does not come with this feature. 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. 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. The polytunnels on our list are all moderately priced, so you should find one that suits your budget. Do Polytunnels Need Ventilation?

In a windy location, you will have to take extra precautions to fix your polytunnel on the ground. Rather than using anchor plates, which are used to fix a polytunnel into a soil base, you can use base plates. 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.Measuring 3-metres in length and 2-metres in width, this tunnel has plenty of room to grow a variety of crops. To compliment your polytunnel we also offer a range of powder coated wire shelving units and seedling trays. 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. One of the things we really loved about First Tunnels was the ease at which you can customise your polytunnel to exactly what you need. 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.
