Thanks everyone for your welcome and your kind comments.
Jim would you fill me in on the term OC. I am planning a shade house enlarging the Dend. pergola after the weather breaks here in the Orlando area. I was planning to use 50% shade cloth for the shade house. We plan to use it for Vandas and Cattleyas. It will have good AM exposure and the afternoon sun will be blocked by a hedge. Suggestions and input appreciated.
Thanks again everyone.
Bud
