I think Cymbidiums do like high humidity. It's the heat that they're not overly fond of (at least the standard varieties that have a lot of the cooler growing species in their backgrounds: traceyanum, lowianum, etc.). While I've been able to grow the standards in this climate, they tend not to flower for me. The madidums, on the other hand, react favorably to the continuous warmth. I do think--from what I've read--that canaliculatum can take full sun. The canaliculatum hybrid I have takes full sun, and it's a primary cross of canaliculatum and madidum (which, I think, means that it's probably less tolerant, thanks to the madidum parent, of glaring sunlight than a full canaliculatum is). Have you ordered from Royale Orchids before? Kevin (can't remember his last name, but he's the guy who runs the place) sent me a few pictures a couple of years ago of the canaliculatums he sells, and they were beautiful plants growing in nothing but granite. I wanted so badly to order one, but in the end I chickened out for fear of what crazy nightmare might be entailed for importing orchids to the US in these exciting times we live in. I bet he'd be a good source for you if you wanted to get a canaliculatum. And good luck with your falcorostrum. The pictures I've seen of that species have been impressive, and I've read that the flowers are highly fragrant. There's a commercial grower in California who carries this dendrobium. So I might have to experiment with it next summer to see how tolerant it is. If it can handle the occasional climb to 40 C in your climate, there might be hope for it here.
In answer to your question, I don't grow any orchids outdoors all year long here. Our winters drop down to -23 C. All of my orchids, however, go outside during the spring, summer and early fall. It's at those times of year when I get fairly carried away and start acquiring lots of plants. And it's at this time of year that my optimism usually comes back to haunt me as I scramble to rearrange furniture and piss off my partner in an effort to find space in the house to accommodate all of the orchids (turning your home into something that looks like an unkempt version of Costa Rica for five months of the year isn't a great idea for endearing yourself to a non-plant enamored significant other
).
