Vanda Little One.......yup, it's a Phal. now!

so i have been wondering about this...Phals are prone to occasional crown rot, vandas, not so much, is that only because of the other cultural factors with Vandas such as high temp and light so they just dry out faster?

I suspect that it's more a temp issue when went. So many Phals are cooler growing and everyone and their mother grows them under every conceivable growing condition, right? My guess is in tropical areas you get very little crown rot even if potted top up, particularly if you have good air flow. If it gets water in crown at 60 degrees and sits there for 5 or 6 days, guess what will happen?
BTW--- phals I have mounted are crown side down. For vanda's, Bob Fuchs once told me that if they are mounted on trees, they should be set at an angle with the crown pointing toward either 2 o'clock or 10 o'clock. He felt they just bloomed sooner in that orientation but wasn't sure why except maybe it gave the roots a better "hold" angle.
