Default Greenhouse installation

live out in the High Mojave Desert, you'd be singing another turn. One that
everyone knows out here.

There are those who believe that life here, began out there, far across the
universe, with tribes of humans, who may have been the forefathers of the
Egyptians, or the Toltecs, or the Mayans. Some believe that they may yet be
brothers of man, who even now fight to survive, somewhere beyond the
heavens.

It would not last here in the High Mojave Desert, on friday we had
65mph
winds and they are coming bact for tonight.


65 mph? That's only a breeze :-

That thing would last about 10
secs out here.

Wow, what do you guys do for greenhouses out where you are?


We get "hurricane" force winds here in southcental Alaska all the
time, but our greenhouses survive. We build with the wind in mind.
Peg 'em down good and build them in the lee of timber, alders, a
tall building, a hillside, whatever.
We get 100 mph wind
at least once every winter here.


Ditto, here in west Scotland. Last winter, the anemometer broke off
when the wind reached 120 mph. At my last place, the greenhouse we put
up in 1984 is still in perfect condition and has never lost a pane
(except once, when somebody shot it).

The most important thing to remember in a windy area, is to keep the
frame locked square and true. If the wind can distort it to even
slightly diamond-shaped, the glass will either crack or ping out. We dug
a rectangular trench and laid a level concrete foundation in it, then
bolted the bottom of the GH frame to it; cheap but that frame will never
distort. The second point, is to keep the doors and vents firmly shut
during very high wind (maintaining an even level of resistance inside,
to the external windpressure).

And earthquakes. (We're about 50 miles
from the epicenter of the largest EQ ever in N. America. The 1964
Alaska quake. A 9.4 -- my DH was a little boy -- he said the cows
and horses all fell down from the ground waves.)


Ow, that's a big one :-(

We're about one mile from a tectonic faultline producing around 30
minor earthquakes annually. (According to the meteorological survey,
which records them). Though in 30 years of living in two different
houses 60 miles apaprt but both on the fault-line, only three of the
quakes were strong enough to for us to feel them. The last noticeable
one in 1999 was a 4 on the richter scale.
