Ooh, I'd love to visit that wonderful facility, and Singapore in general. My husband has been there several times on business, but I had to firmly "encourage" him to go and tour the big facility.
Sunny, the Phals are not trained to cascade downwards like that, it is their natural way of growing. The plants naturally attach to branches and trunks of trees with the leaves and flowers hanging down.
Standing upright with stakes on the stems like we see them here is completely unnatural, and is one reason so many people fail with Phals - the cup of leaves needs to drain so they don't develop crown rot, and facing upwards prevents that. Growers aren't motivated to teach people this, since they sell more orchids if people kill them off. Plus, you can pack more of them in a box with flower stems standing up . . .
