Re: Polytunnel puzzle.

Ian,

I've never tried anything so grand as what you describe, but I use
tunnel cloche quite often.  We have some fierce winds here, and the come
from two directions -- the dry wind from the east and the wet wind from
the southwest.  I have terrible problems with the ends of the cloches. 
I have always though that I should build a separate frame to fit the
ends, and perhaps streamline it to better shed the wind.  Shaped
something like one of the "leaves" of the Sydney opera house, perhaps
;-).  But it always seemed too much trouble for a short (1M high) tunnel
cloche.  May be worthwhile for your greenhouse.
