Mariana,
That's a pretty tall order! With the snow loads you will need to
contend with (don't want two feet of snow dumped on your Catts!) and the
temperature you will want to maintain it will be a challenge. I suggest
you take a look at the technical info at http://www.sundancesupply.com .
They have a great deal of information about materials and load bearing
capabilities of various material. They also have a calculator to figure
what size heater you will need. http://greenhouseconstruction.com/ also has
a wealth of information. For a prepackaged kit the Rion line of greenhouses
gets alot of "bang for the buck." One last bit of advice...get the absolute
biggest you can fit into your space and afford. I will only be a couple of
months and it will be too small! It is well worth the investment. The
plants really do seem to grow better (for me at least).

Okay, my husband finally had enough of the orchids taking over our living
space and he threatned me with bodily harm g if I don't quit buying
them.
We've come to a compromise. A greenhouse. We agreed on no more than
$2,000
which should cover the (minimum) heating system for winters, and possibly
a
misting system, and fans to circulate the air. I want the greenhouse to
be
large enough to accomidate anywhere from 200-500 orchids.
I would love to hear recommendations, pluses and minuses of growing in
greenhouses vs. a house and any other information that you think will be
usefull.

I reside in New York City and have about 400-500sq feet for this plan.

Thank you in advance,
