There was a dealer traveling through town selling fiberglass
greenhouses. The brand is "Solar Optic Greenhouse", by Imperial Systems
Inc, in Summerland, BC.

The building seems well made and it comes with a 20 year warranty (if
they are still around in 20 years). For the 8 X 11 ft model it has two
automatic roof vents (they work on heat expanding oil in a cylinder) and
a manual window in the door and back wall. They say it's good for 100
mph winds.

If you get in on the truck load price, it's $2445.00 assembled on your
lot. You would have to grow a fair amount of plants to make it pay, but
I'm not sure if that price is very high or about normal.

Here in south central New Mexico water is getting to be a real problem.
I assume that the humidity inside one of these goes up from the
evaporation, then water loss is much less than out in the open.

According to the brochure (and they wouldn't lie, would they?) even in
hot climates the plants will be better off inside this building with the
vents open than out in the sun. When the days get over 90, and we have
a lot of those days, most of the plants just stop doing anything. All
this sounds too good to be true, and my experience is that if it sounds
too good to be true, it probably is.

Does any one have any experience with this brand of greenhouse? Does any
one have experience with fiberglass greenhouses in the summer in the
desert?

Thank you for your opinions.
