I know a lot of growers say to water the phalanopsis when the media is completely dry, I tried that with a previous orchid and its leaves cracked from not having enough water and the roots shriveled up and it died. It lived in the same location as my current orchid and the only thing I changed is more frequent watering.
I also water by drenching the media under a running tap for like, a minute or so. I'm careful not to get the leaves wet as from what I understand, if they get moisture in a little nook or crevice they can rot. I drain it well before returning it to it's blue pot thing and I check for any excess water sitting at the bottom of the blue pot
