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.
