In my experience, vandas do best when they have a full root system hanging below them. You say you cannot handle the watering with such a method, yet you said in another thread that watering for mounted plants would be no issue, so I’m a bit confused.

Second, I think your greenhouse conditions are entirely too cold for a vanda. 22C would be close to the lowest nighttime temperature the plant should experience, not the highest. 30C or higher is more normal.
