I have quite a few Laelia anceps. I grow them in 100% hydroton and in clay pots.
umm....Light....bright light but make sure not full sun, otherwise the leaves will scorch/burn. I water mine depending on the season: Summer/spring 3x a week at least, if not more. During rainy season--I don't touch my plants; and usually bring them in for a one-two week hard drying period so I don't get any infestation or fungus, etc. Then they go back out and I repeat this if I see too much continuous rain. During the winter--I hardly water--maybe once a week. I left them out in the cold last year when it got down to the 20's here and they were perfectly fine. So, they live outdoors the entire year.
