I'm typically not a fan of white flowers, but that's cool!
According to a Baker culture sheet, light should be moderately low or dappled shade at about 1000-1500 fc, minimum temp of about 65°F, with heavy, frequent watering, and lots of humidity and air movement.
Simply stunning. I have been lusting after one of these for over three years now and it’s the only orchid, so far, that I am just too terrified to buy.
You’ve done a wonderful job getting that beauty to bloom!
