Advice needed for Vanda tricolor

[Fairorchids]

For a number of years I grew my Vandaceous plants in full sun from June through Sept, after hardening under a lattice for 10 days. I could get away with this, as I worked from home and I would spray them down at 10 AM and again at 1 PM every day.

Vanda tricolor does well in full sun, but it also blooms reliably under Cattleya conditions (abt 35% shade). Obviously, early morning or later afternoon sun is not a problem.

Thank you all for the great advice. The plant seems to be doing fine underling a couple hours of full sun. Hopefully the roots will establish in the pot soon so it would resume growing.

Right now it is hot in SoCal (~80 F day and ~mid 60s night). Since I am growing it outdoor I have to water it everyday or every day and a half with very, very diluted fertilizer, and Dyna Gro K-L-N once a week.

Speaking from personal experiece: I grow a Vanda up in Norcal. It was originally in a clay pot with bark and charcoal and did reasonably well, but during the winter had issues with too much moisture. I've since unpotted it and hung it rootless draped in spanish moss outside in the breeziest area that is bright but shaded slightly by a tree. Temp for the summer hang around 57F night and 78F day high. Humidity is usually around 40-50% because it's sitting over a table of huge cymbidiums. I kid you not, not a week after I unpotted it, each root started branching. It gets watered every morning at ~6am to let it soak in without evaporating too much, and misted again at noon. Soaked in a bucket every 2 or 3 days depending on heat. It couldn't be happier!

From what I can see, vandas like their root systems to be fairly dry but humid, so if you can do that, whether it be loose, airy media or none at all, you're gold (or tricolor in this case)!
