I've got two: a bellina and a violacea "Malaysia", and a primary hybrid Valentinii (cornu-cervi x bellina). I don't treat them any differently than my other phals. They're outside under shade cloth from about March to November, and under 4x40 watt fluorescents November to March. I grow in clay pots with sphagnum moss, fertilize with balanced time-released pellets, and water (with a hose or at the sink) whenever the top of the moss gets dry. Outside in the summer, this can be every other day sometimes; inside under the lights, it's about every 3-6 days, depending on the pot size. Maybe it's just the fortune of my good climate, but I don't do anything special for them and they do well for me.
