I've never been sucessful with Phalaenopsis till I tried this experiment which is a modified version done by a friend who grows a number of Phallys. Its almost a semi-hydro culture be the plant never gets near the water but the roots often do.
The plant is in a 75mm squat pot with a mess type drainage base. It sits in the top of the plastic glass which has 2 holes drilled into the sides about 25mm up from the base. Water stays in the glass like semi-hydro but the distance from the base of the plant pot to the water is about 60mm. See what happened after a month or so. Look at the old leaves and then the new one.
