I have just got two self fruiting cultivars of this orchid cactus which create enormous night opening flowers up to 16" in diameter and create large red spike covered edible fruits (in time - mine are about 10" long only). Is there anyone else here growing these? Since they are epiphytic from humid tropical forests (they create areial roots) I was curious to know if I could mount them to cork bark and grow them like my mounted orchids in the hot lowland Nepenthes chamber as long as I didn't water them directly just letting them subsist on the humidity for the most part?
