Richard, Phals don't like change or direct sun so growing them in the house is a good thing. Your challenge will be keeping the humidity high enough for them. They should be kept fairly wet but allowed to dry between watering. Once you find a spot that makes them happy, let them be. Re-pot when the bark breaks down and turns to dirt. Most of us grow them on an angle to keep water from setting in the crown which may cause crown rot and kill them. Best of luck.
