The polytunnels on our list are all moderately priced, so you should find one that suits your budget. Do Polytunnels Need Ventilation? I’d strongly recommend doing the same if you can as it is much more fun when other people are involved. Digging the foundations Frame built, cover ready Doors on, mission complete! 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.

And once a plant has been infected, there is, most of the time, no cure. All you can do is remove the infected plant.Whether you’re new to gardening or a seasoned pro, for in-ground growing with the protection of a PE cover, choose the VonHaus Polytunnel Greenhouse . 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. Ventilation is one of the most important things when it comes to a polytunnel. Because of the way a polytunnel works, moister build up is a common occurrence. 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.

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 well ventilated polytunnel will keep moisture levels in control, but also ensure the polytunnel does not get too hot. 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. 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. There are many vegetables that you can grow all winter in a polytunnel. Or maybe you need to bring in some of your outdoor plants to overwinter them. I would always recommend buying the best quality for the price you can afford, even if that means shopping around a bit.

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. Some people will recommend to go as big as your space allows, but if you then don’t use all the space in the polytunnel, you might regret this.

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. 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. You could also consider growing a hedge to break the wind, if the wind tends to come from one direction.

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. Another consideration you should take into account is whether you are planning to heat your polytunnel or not. 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.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.
