I adjust my watering pace as season changes. A little more frequent during hot summer days, more interval during the cooler months to winter. During summer too I make sure a window is open if it is not too hot outside or I let the ceiling fan run all day long to help cool down & dry out the Phals as well as other orchids. I prefer to dunk water my Phals up to root zone, never to the crown for a few minutes then allow it to approach near dryness but not too dry before next watering. Especially when they are laden with buds and are blooming, got to keep them well hydrated, otherwise, it may blast the buds. They are low light orchids, so I draw the curtain, so it won't get sunburnt in the afternoons.

Drying out of your media depends on what type you used too. I prefer mixed bark and coco chips. Some prefer to use sphag moss..but I try to steer away from sphag moss..it holds too much water. Whichever type you have, just make sure it allows the Phal roots to breathe.
