Direct sun
Most orchids do not grow in direct sun in their natural habitat. Most get mottled shade from the sun passing through trees, etc. We use shade cloth in our GH to reduce the intensity of the sun and the Marfitch "Howard's Dream" still has to go in a shadier area in the summer. I wouldn't put any orchids in the direct sun in the summer. However, toleration of sunlight is also influenced by air movement and humidity so it isn't a simple, "cookie cutter" answer. As I said, watch the color of your plants and don't be afraid to change the locations around until you get the one that works best for you.
