Yup, but there are so many bamboo-lovers that I thought I would use their term.
Stem? Shoot? Pole?
I just wish my little F. rufa would look more like a broom-handle and less like a straw.
One thing I tried with cheap, skinny bamboo poles from Home Depot stiffer was to lash two together, parallel, with their thinnest parts overlapping around 20-30%. This made them a little stronger and longer.
From your link, I like the idea of using 4" lengths of flexible black water pipe for film clamps. I've seen white PVC sections sold for that purpose, but how much 'spring' can PVC have?
I'm lucky to very seldom have much wind. But on a windy day, I would have to either rush home and move hoop tunnels under cover, or attach return postage to them.
