Pergola building advice for Vandas

[MiamiBorn]

Hi! I’m new to the board. I live in a South Florida in zone 10b. I grow Vandas mostly (35+) because that’s the environment I have.

For many years I have grown them in or under trees with sprinklers, but because those spots are no longer available, a new home is urgently needed. So, my plan is build a stand alone structure with a polycarbonate roof, a sprinkler system, a fertilizer portioner and a cold protection method. Really tired of bringing them into the garage when we have our infrequent cold snaps.

I need advice. My current thought is to buy a aluminum pergola kit as a basis, 10’x14’. Other options like wood or cellular PVC are too expensive. The material must stand up to our subtropical weather. The option for matching the color of my pool screen with aluminum is appealing.

Anyone had any experience with aluminum pergola kits or any other kits? Vinyl? Any advice would be appreciated.
