last year about a week from now
on the dreaded 10/30 Halloween storm from
hell 
that fried all my electronic stuff in the house
and CRUSHED my Big hoop house like nuthin...
i am still salvaging parts and making lemonaide out of lemons
this is my "little
greenhouse" (half arch) thats heated by two ac's
that freshin's the air inside sending warmed air outside into a
contolled space.....
and,,, it can work in reverse when in "
FAN mode"
you can Siphon hot air from within the green house (7' x 21')
and send it inside the house for reducing the oil consumption.
Threaded Mode
