There is a section that covers semi-hydro in the forum that members have posted plants in. This is probably not the correct term for this plant, its more a semi, semi-hydro. The phal is potted in an 80mm pot in bark, volcanic rock and crushed quartz. The pot sits nicely into the top of the clear plastic disposable glass in the second pic. There are 2 holes, one each side about 25mm up from the base. I just sit the pot in the glass and water normally, the water in the glass provides humidity and the roots grow down to it and don't seem to rot, they love it.
Semi-hydro growing by many members including myself use the glass as I have it but the plant is potted directly into the glass using Hydroton (expanded clay balls) or similar.
