Do I really need to go up to Cattleya light to get Paph. haynaldianum to bloom or can I get away with lower light?
I have a growing section with Polychilos Phalaenopsis that I keep really warm and brighter than "regular" Phals, more like Oncidinae, which I think could make haynaldianum happy, but reports from growers complaining about it being super slow to grow are a concern!
