Just thinking your plant may also be Ascda. John De Biase 'Blue'. This a common plant sold around the world.
Found some photo's on the net and I am about 80% certain that we are talking about that particular specie.
Is this plant a heavy drinker or somewhat dryer?
Vandas / Ascdas from my experience like a good drink every day in the summer but dry out at nite. Humidity should be high if possible, never dry air. I water once every 2 or 3 days in the winter even though my plants are kept warm, its not as warm as in the tropics at nite by a long way but the plants don't seem to mind if they are kept on the dry side.
