I've been working with small and miniature orchids for a year or so but I just got my first Cattleya in May. It's doing very well on my east facing balcony, with four new pseudobulbs growing so fast that I can almost see it. My question involves bringing it indoors in the fall. How important is photoperiod? I plan to give it artificial light in addition to what it will get in an east facing window to give it a 12 hour day since this is what a tropical plant would get at home. But I read somewhere that they should be treated like a Christmas Cactus and not get any artificial light at all. This doesn't make sense to me, so I'd like to see what experienced members have to say.
