Still, I guess even a few years usage would be ok, although I don’t like things going to landfill so the longer it lasts the better. The versatile tubing is robust enough to resistant kinks and abrasion and its ergonomic design reduces associated strains and fatigue. In the US they tend to use straight lengths of pipe which then bend and form and arch under their own pressure (if that makes sense). Commonly used in the chemical, pharmaceutical and electronics industries, this RS PRO flexible tubing is silicone-free and complies with standards for hoses which are to be used with compressed air (BS 6066 and ISO 5774). To address jay-el's point about the height I was gonna have about 100mm of pipe attached at each side with two clips in an attempt to force an amount of straight edge before the pipe bends.

RS PRO Hose Pipe, PVC, 12mm ID, 17mm OD, Blue, 30m | RS

The blue pipe is meant for underground and not uv stable - not that this matters when using it for hoop houses. The internet/youtube is awash with people using pvc waterpipe to make arches for their raised beds, which are then covered with clear plastic (to make a greenhouse type set up), or netting (to keep insects and birds away from crops. It is also EC-compliant for food-contact applications and RoHS (Restriction of Hazardous Substances) compliant.

The clips to hold the net on are made from the same blue pipe, about 4 inches long, split and rounded.

RS PRO is our own brand range and brings you a wide range of high-quality, great value products offering you more choice. Looking at people’s structures it seems to serve the purpose perfectly, I had ruled it out at first thinking in would be TOO flexible. Lightweight and flexible, the 30-metre long, high-quality PVC hose doesn't compromise on performance or durability. My beds are 8x4 and I cut my tube at 10 foot length which gives me enough to arch over and push in the soil either side. I guess I’d also have to think about the overall height because my beds are a little wider at 5 foot….

Would definitely like to use black if possible, although I have now heard contrary arguments; that it would be more UV stable vs it would degrade quicker. There's yellow pipe as well meant for gas but I don't think that it's any better than the blue and I think it's a bit dearer.
