Advice on Polytunnel cover needed

[FuckYouChrisAndThatHorse]

I’ve been given an old polytunnel frame, and now I just need a cover for it. Are there any pitfalls I should be avoiding or supplier recommendations?

We do live somewhere windy and I’ll be using it to grow all the usual garden veg and lengthen my growing season.

Many thanks!

You need proper UV stabilised plastic
somebody like Two Wests and Elliott will be able to sell you the right sized piece of the right plastic

Thank you, that’s really helpful
