I recently inherited some Bulbophyllum frostii, Bulb. Macrobulbon, and Bulb. dearei x lobii. I live in a subtropical warm and moist climate off the southeast coast of the US. How much light and moisture does a typical bulbophyllum need? I am having a hard time finding growing information about them. I am a hobby orchid grower, so I have a greenhouse and materials, but don't know much about this particular species. Thank you.
