Phal corningiana is not a lowland species. Sunlight requirement similar to that for Phal fasciata. Watering level is similar to Phal sumatrana, bellina & violacea. Culture in basket (i.e. free-draining pot with lots of sphagmum moss mixed with limestone & perlite) produces far superior results than plants mounted on tree fern. Temperature needs to be cooler to initiate flowering.
