Les,
If you will send me your snail mail address [or a telefax number if you have
one], I will send you some pages from a publication on installation of fans in
greenhouses for circulating air properly. You don't mention what your vent
situation is -- ridge vent, window vents, etc.
You might want to look at www.charleysgreenhouse.com for wall vents, which I
use for intake at the bottom of the greenhouse -- we use a ridge vent at the
top for the hot air to escape.
Another consideration is shade cloth, which is also available from Charley.
Reducing the strength of the sunlight by 65% or more is not a bad idea. Here,
the spring is our most difficult time in terms of temperature control, and on
a sunny day, the greenhouse can get up to 90 or 100 degrees F if we do not
watch it. The deciduous trees that shade the greenhouse during the summer,
being bare, let lots more light in in spring and fall. [My Night-blooming
Cereus is sunburned!]
