Given the problems I’ve been having with my cheapy polytunnel, it struck me today that I could turn it into a kind of polycrub given, say, some recycled scaffold boards for the sides and six sheets of twinwall polycarbonate.
I don’t think I’d need to use particularly thick polycarbonate, but even so I am slightly unsure about how well it might bend over the relatively tight radius of the tunnel. But then it occurred to me that I might be able use the sheets horizontally and overlap the edges (like tiles). Where it comes down to the timber on the sides I might even be able to install gutters for collecting rainwater.
Even three metre sheets of 6mm twinwall polycarbonate aren’t exactly cheap, but I suspect it might be possible to get them and all the necessary fixings for around £300. I know there’s somewhere local that sells off used scaffold boards, too.
Can’t let it get too far up the priority list though. Need to get some other projects finished first.
