They probably get their polycarb from someplace like Farmtek

When I built my GH I took the position that I wanted to have the most light
available, figuring I could always subtract light by using shadecloth, but I
could never add light, and since light is the limiting factor in getting
blooms I went with clear dualpane polycarbonate. You might want to look at
this page at the Farmtek site.

There are loads of sites on the web that discuss GH siting and construction.
Charley's GH has a lot of info about building a GH and sells overpriced
kits. Costco has decent prices and packages on their GH kits. Sundance
Supplies has a ton of info incase you want to build/design your own (you
have to dig around to find his info on construction, IIRC its under FAQ, but
look for yourself.).

What ****ed me off about kits (and why I decided to build my own) was
becasue (at that time) the kits cost thousands of dollars and all you got
was the exterior building. No benches, no fans, no nothing. I figured for
the same thousands of dollars I could buy wood and build it myself, bigger,
taller and cheaper. Which I did. But that ain't for everyone. Nowadays
kits are cheap. I saw one at Harbor Freight 10x12 and 11 feet tall for
about $700. You can't beat that. Not with a stick Plus sometimes you can
get a 15% off coupon in their flyer. Now that's cooking with gas!

I am considering building a greenhouse for my orchids. It is the humidity
that I want/need. Living in Southern California, low temperatures are not
much of a problem.
Also, seems like most orchid growers in the area (Normans, SBOE) use shade
cloth or opal translucent polycarbonate panels overhead.
I am looking for a greenhouse kit with these opal translucent
polycarbonate panels for the roof. All that I can find seem to use clear
panels.
What are you folks using? Clear glass/polycarbonate with shadecloth or
opal panels?
Also seems that clear glass would make the GH hotter than heck, even with
the use of shadecloth.
Thanks for any advice.
