OK...well these Bulbos. need warmth! and of course, humidity. They appreciate bright positions and a slight cut back on the water after flowering, though they do not need a definite rest period. This little cut back on water will help the plant a lot, but only do it for about 2-3 weeks and maintain plant well watered after that. It kind of triggers it to start growing again.
Apart from that they are pretty easy to grow, but again, make sure you keep them moist and in bright light (cattleya light).
Hope that helps
