When choosing a (small) tunnel is it worth having one of the more expensive covers?
By this I mean either double-thickness (like super-bubble wrap) or reinforced with fibres.

By the way . .
I have experimented this winter (not realising that the temperature would descend to minus 13C) with a low tunnel over broad beans.  This has a green mesh cover (that stood up to the snow!).  Beans in the open are dead, but those under the tunnel look to have survived.
I rather suspect that it was the snow that insulated them, and the ground that kept them warm.
(the picture is just to compensate for all the dogs)
PS I have reduced the picture size, having been told that it would appear on all my posts.  I do not think that this is correct, as this is not my signature, but Ah! So!  I tlemble and obey.

Sorry I can't help you there Colin.  We bought our tunnel 2nd hand over 5 years ago.  It has ordinary poly over it, which is still there, albeit rather riddled with holes and splits that I keep repairing.  It was 5 years old when we got it and they say never re-use the poly if you move the tunnel, and the poly only lasts 5 years!  And we live in very windy Lincolnshire!!

But ours is now nearly 10 years old, and will hopefully last me another growing season, if I can get Brian to take his spare wood, 3 lawnmowers and 2 rotavators out of it!!!
