Good question DC. I don't have the answer. I just used to get them started early spring then slowly push them out further beyond the shade line until they got to full sun, other than hottest part of day (like 1:00 to 4:00).

It depends on heat and air circulation. Sun hitting the leaves can quickly raise their temperature enough to burn them, especially in a hot southern climate. If there is a good breeze the heat is carried off and leaves remain at ambient temperature. Evaporative cooling from normal transpiration also helps, but if the plants dry out this is greatly lessened. Most people jn hotter climates need to provide some shade for Cymbidiums.

I have my Cyms under about 45% shadecloth. When I first moved to my house, I had them completely unshaded. They survived, but looked stressed... they have grown much better with that shadecloth taking the edge off, especially since that part of my yard is in blazing sun from half an hour after sunrise to half an hour before sunset in the middle of the summer. So duration of the hottest sun is also important. The hard-leaved Cyms (like aloifolium, finlaysonianaum, suave, etc) can take more sun. still, they'd need to be acclimated.

Most excellent.

I have chosen their new home under the front eave of the lath house. They will get the most light they can in winter and be protected in summer.
