I make my own hoops using the blue plastic water pipe used for drinking water. It can be bought from DIY outlets or agricultural dealers. Tried the black version first but too thin a wall and didn’t last. Now use 20mm Blue and it is great. I’m near Peterhead and it gets very windy here but the enviromesh is fine on my raised beds.
Plastic pipe is cheaper than aluminium. My beds are 4ft wide so all the hoops are the same size and I just use different length canes for them to sit on, acording to crop height.
