I'm in the process of buying a small greenhouse. I'm looking for a very
sturdy frame because it'll be put in a windy location

Having lost a glass glazed greenhouse in a storm 8 years ago ... I
replaced it with a twinwall polycarbonate glazed greenhouse ... I've now
purchased a greenhouse of the same size (6'3" by 8'5") which I can bolt
to the same frame,

Hi, Malcolm, thanks for your reply. Have you replaced your polycarbornate
with glass? The problem I've had is that the frame on my greenhouse is
quite flimsy and so it bends in high winds and of course the glass then
shatters. I thought that polycarb might be less inclined to break if the
greenhouse frame moves. I also like the Elite greenhouses, but I've only
seen photos of them online.
