I'd go with the clear 90% sun transmission then get shade cloth to cut it
down to the appropriate strength. You can always add/remove shade, but you
can't add sun.

As to shade cloth, IMHO use a meter in order to set your shade.

Hi all,

I will cover my orchid greenhouse with polycarbonate corrugated panels of
the company SUNTUF.
Would you send me the best color for this one ?

All panels are 100 % UV protect.

Clear ( 90 % sun transmission )
White ( 45 % sun transmission )
Grey ( 35 % sun transmission )

I have many Cattleyas's alliance.

The internet site of Suntuf is :
