Now that I'm back in San Francisco, one would think it will be much easier to grow the Cyms. However, San Francisco has a multitude--by some reports over seventeen-- of different microclimates, illustrated below.
My simple goal for the Cyms since their move is to just survive and produce new growths. Most are complying, but I think I've lost two or three plants. For myself, the goal is to learn about my new microclimate and its changes throughout the year. Below is an equivalent graph of the 2012 temperatures per the weather station closest to my present locale. You can see that the temperatures are fairly even throughout the year. Given that my local temps infrequently go above 70F, I no longer have a strong need for heat-tolerant Cymbidiums, and I'll be curious if my existing heat- and warmth-tolerant Cyms will flower for me in their new environment.
Below is a graph of light readings on a sunny day: a nice smooth curve. Such a rare occurrence here.
Below is a graph of light readings on a foggy day. You can see how variable the light levels can be throughout a single day.
Here the fog burned off late morning and yielded a relatively sunny afternoon.
It is going to be a challenge to provide adequate shading for the Cyms when they are exposed to direct sun but also allow for sufficient lighting when under fog. There are already some sun-burnt leaves here and there while I find the right balance of shading and the plants acclimate to their new environment.
