Understand now.  Had visions of a proper greenhouse inside it!  I was planning on making a couple of cold frame covers to go over some of the raised beds to help keep things a bit warmer  in the tunnel.

Oh it is a proper greenhouse - 8'x6', aluminium and glass, just not the hyper toff type Alan Titchmarsh has  :roflanim:   :garden:
In fact, does anyone want to buy it, S Lanarkshire?

It does  ;D  - I've described it in my long message above, if you can plough through it.  The one time it did it poked quite a big hole in the polythene but it mended well with repair tape - fortunately poly cover tears don't seem to 'run'.  The greenhouse would be better being further away from the sides.  My polytunnel is quite tall, 10' I think so it doesn't hit the crop bars or the middle of the polythene.  If I'd realised in advance how much the tunnel structure flexes, and how much the polythene stretches in the heat, I would have put the greenhouse more centrally, or facing the same way as the tunnel - at the moment it sits across the tunnel and one apex comes to within about a foot of the south side wall of the tunnel.

We have a first tunnels 60' x 20' tunnel and it is rock solid. They build their tunnels with closer hoop spacing than other makes specifically for this climate, it shouldn't rock at all. Have you contacted them for advice scribble?
