Has anyone made or purchased a polytunnel covered with enviromesh and would this possibly be an advantage over polythene ?
Do you mean a polytunnel that you can walk in and out of or one that you cover low plants with? ??? ???
I make some semicircle hoops with heavyduty wire I found in the garage which supported some environmesh I got from our lottie trading post, whole lot for under a tenner. No cabbage white this year at all.
If you buy the readymade ones, they are very expensive.
Advantage? Enviromesh breathes & is water permeable.
My neighbour uses one for growing show leeks, but i've never tried it.
I get my enviromesh from Suttons. 2 for approx £32 with postage. Garden Warehouse LBS do a huge one for £250 quid. It does last though lol
I bought 12 metres (2m wide) direct from Agralan last year, but think they now sell through this site:

I got some from here because it's just the right size for my beds, free p&p:

They're a couple of useful sites - thank you, I've bookmarked them :) :) :)
