Light Levels

Something to keep in mind when looking for information about your plants online is where the person is actually growing the plants. So much of what we read about Catlteyas and other types is that they are probably not getting enough sun. However, that turned out not to be true for us. Ours were turning yellow from too much sun! They weren't getting sun burn spots, but they were getting sunscreen pigment from the sun, so it was confusing. We also have to move all of our orchids around on the porch seasonally since the angle of the sun changes and different parts of the porch get more or less light. Our Cattleyas get a few hours of direct morning sun and a few more hours of indirect light. The Oncidiums get a couple of hours of direct morning sun and several hours of indirect light. The Phals get very little direct sun and lots of indirect light. Our 2 leaved cattleyas seem to prefer a bit less light than the single leaved cattleyas.
