The amount of light you may need for your chids depends on the type of orchid you have. For example, Phals don't need as much light as say a Dendrobium. Depending on which chids you have, you may be able to place a chid that requires more light closer to the window with one that requires less light in a second row behind the ones requiring more light. I also have some of my chids under artificial lights--they are too far from the sliding door to get sufficient natural light. Of course there is no such thing as just one or two chids, so we all have to be creative at one time or other; I know I certainly did
