There's no standard watering frequency. It depends on your conditions (air humidity, temperature, light). But the transparent pot is your best friend, and the roots will tell you when they need to be watered. Green roots are wet, they don't need to be watered. When at least 95% of the roots are silvery white, it's time to water your phal.
The same phal in the same spot on your windowsill will need to be watered every 15-30 days in mid winter, but every 3-5 days in mid summer. The roots will tell you.
