I have aclandiae, tho not yet bloom size. They like quite high light. While growing, water just as media becomes dry. In winter, they like to be a dry, with bright light. Right now, I am just lightly spraying the media surface every couple of days - a bit less often if weather is very damp. I don't know yet if my winter watering is proper to get blooms or not tho - hopefully someone who blooms this species will chime in. (Same goes for the two others you asked about)
