Review: Excellent value. - Excellent. Strong. Straightforward to assemble. This is our second tunnel and a good one. No problems assembling - just a bit of thought needed.
Review: but all frame holes lined up easily, and the Allen headed bolts tightened securely with ... - This is the third 6 metre poly tunnel I have bought via desertcart, the others being the "Palm Springs" and the "Polly Poly" tunnel.This boldly claims to be the strongest, and it does have a central roof strut the others lacked, which makes a dramatic improvement to overall stiffness of the frame, and prevents the inevitable build up of water on the roof, if the cover is less than drum tight.Another very thoughtful feature, are the vertical holes around the base, which permit pegging the structure down, without tearing the cover.The tube itself however, is not unusually strong, and decidedly lighter duty than the "Palm Springs" version, though this has one less hoop.This tunnel also starts to curve in much lower than the "Palm Springs", slightly reducing the usable floor area with taller plants.The all bolted construction is slower to assemble than the usual spring loaded pins, but all frame holes lined up easily, and the Allen headed bolts tightened securely with the supplied spanner and key, and more easily than struggling with a spanner and screwdriver or pliers.A good tip, is to only do up the bolts finger tight initially, as they can be fully tightened so much easier, when the whole structure is standing Unfortunately the labelling was a complete mess, with the numbers mostly missing, and one puzzlingly on the wrong component ! Anyone not familiar with greenhouse construction, would have been baffled. The cover was a perfect fit, unlike the "Palm Springs",which never did zip up properly, but unfortunately only has a door in one end, which makes it more awkward to slide over the frame in a confined space, as you are not dealing with a flat sheet.In my case I realized this too late, and after struggling for half an hour to fit the cover, had to take it off and turn it around.The unbranded zips look robust, but lack the proven quality of the "YKK" examples on the "Polly Poly Tunnel".The seams were accurately sewn, but this cover is without the generous reinforcement of the "Polly Poly Tunnel", and the attachments for the guy ropes, look so flimsy as to be useless.The gauge of the polythene is only 150 gm, and certainly no heavier duty than any cheap tunnel.The side windows are only held shut by very small pieces of Velcro, and look like a weakness in rough weather.The worst feature of the cover is the miserly overlap all around, of less than 6 inches.As this is the main thing holding the tunnel down, why are all these allotment tunnels so penny pinching in this vital area? What is more annoying, the instructions specify a 12 inch deep trench, promising a generous overlap.This involved two hours of arduous digging through stony and tree root filled soil, when half a spade depth would have sufficed. To sum up, a thoughtfully designed and nicely made frame, seriously compromised by an average cover, which needs reinforcing and sensible overlap.
