RE: Constructing a greenhouse


Summer heat in a greenhouse is a real problem almost anywhere. Two
alternatives would be high density shade cloth  or growing a fast
growing vine on netting over the greenhouse that dies back in the
winter.  I have a friend who solved the problem by having a normal roof
and clear side walls. Hers is the only greenhouse I've seen that is
really useable in the summer. Here in Memphis with both temperature and
humidity in the nineties frequently a clear roofed closed green house is
just about unusable in the summer.

I have a greenhouse of twin wall polycarbonate.  The long side faces
west
(no choice but to use this layout on our property) and it gets REALLY
hot in
late spring and summer.  And yes, it has vents.  I empty it out about
July
because it gets so hot. I don't think double glazing would make it
cooler;
if anything it would make it hotter in my experience.

that
