Jachilles, this is an old thread. Phalaenopsis roots, like Vanda roots are big. When one of these plants need water, you can sort of tell by the color. When you water silvery roots, it should turn green--this signifies the root is hydrated. How fast the color changes is indicative of how hydrated to root is before you watered.
Most orchids also have this same kind of behavior but the roots are not as large and as notable as Phal or Vanda roots. BTW, Phals and Vanda are relatives.
