Orchiata question

[greenpassion]

Hi all. I have a few phals that I've repotted in medium grade orchiata. I have them in clear pots, and on a heat mat. I've read on here that orchiata is not as absorbent as bark, and so may require more frequent watering. I have thus far been successful with my watering by checking to see if there is any condensation on the sides of the pots. Now I'm wondering if I should water more frequently, even when I see that condensation. I know about the skewer method, but for now I'd like some advise about the condensation inside a pot with a phal potted in orchiata.
