Is this a BS tip? LEAVE water in bottom of phalaenopsis pot

[Denizf]

Hey all,

I’m on a local houseplant forum and someone provided this sus tip regarding phalaenopsis orchids:

“…put the orchid pot into the cache pot and leave at least .5” of water at the bottom. This will create a fungus that triggers blooms(learned this trick from my Boss that has 18 orchids that are decades old) also the blooms should stay for about 2-3 months 🙂”

I don’t know, but this is counter to everything else I’ve come across. Thoughts?
