Decided to take a chance on this polytunnel after taking on a large allotment. Reviews here and elsewhere say that it is flimsy and doesn't survive windy days. I disagree!! This has been through 3 named storms this year and there has been no damage at all. I followed advice on YouTube and dug a 6" deep trench which the bottom rails of the frame sit in, You then tuck the cover under the frame so that the ends are inside and there is no gap for wind to get in. Backfill the trench once the frame is bedded in. As for the entrance flaps, you can't fold them under, or you won't be able to zip it up, I put a line of cheap bricks on the flaps, and this has meant the wind can't get in. The other thing to do is get some hefty stakes and put one in each corner, secure these to the frame with cable ties. Finally, criss-cross some ratchet straps across the outside of the framework to keep the cover in tighter on the frame. These simple remedies have ensured that this polytunnel now stays in place. The space inside is HUGE, I've a table and 6 growbags in there and there's still plenty of room.
Look the cover is a fine quality- the frame is sturdy however the attachments are woefully inadequate.
The 1st tunnel I ordered had a broken zip. After about a week and some back and forth of emails I had a replacement at my door. The tunnel it’s self is good value for the money and the service I received is 5 star. Would definitely buy from this company again.
It's big enough inside for what I'm doing it fits 6 pallets inside I find the cover to be loose would have liked it a bit of a tighter fit not sure how it will last in a strong wind as bars aren't super heavy duty but saying that I'm enjoying it so far and having a lot of fun it so far that I'd recommend it
Making my first purchase a couple of weeks ago I was in two minds whether this company was legit, bought this poly tunnel and it arrived two days later, free postage usually means a week but not with this company. The item was that good I bought another a week later and again arrived very quickly. Will definitely be shopping with GardenArch again!!
