hmm, one of the vandas is on the back wall facing north and it gets light but no direct sun. The other 2 are newer and are mounted on wood with a hanger, actually made from a coat hanger. I bought them on a street corner near the main market a couple months ago, they probably came from Veracruz. Anyway, I have them hanging on the filter of the indoor pond and for now they get about an hour of direct sun and lots of light. I dunk them in the pond water every day and hope that the fish poop counts as fertilizer. I will have to move them in the fall though, the sun moves lower and does not come directly in the overhead opening in the winter. Maybe I can work out a space for them on the roof that isn't too hot. They can have a winter home and a summer home
