Wow! They're fabulous Bud!
And you're brave! My vandas are still hanging ang getting watered 3x/day. A few are blooming but I've killed a few maybe because of my overhead sprinklers. Maybe it doesn't like getting its crown or leaves wet.
Growing on a glass with only the roots getting wet seems like a great idea... I'll try that on some of my baby vandas. Thanks for showing some proof that it works!
