I'm having good results with exstaminodium, wallisii, lindenii, in basket culture. Cooler end of intermediate temps. Almost Cattleya quality light. Very breezy, close to the swamp cooler.
Water is the same as for everything else I have. RO/well mix at 20-40ppm hardness.
Winter fertilizing at 40-50ppm N (K-lite fert..of coarse), weekly.
The consistent scary issue with long-petals that I've had (common for just about everyone else) is erwinia. But since going K-lite, with amped up Ca/Mg, I've seen very little erwinia.
