I only have Psy Kalihi at the moment. Had it for just under a year and it's 2nd flower is getting ready to open for this year. The extra good news is that it has sent out 2 more spikes so I'll have a sequential triad here soon!!! There is so much conflicting info on light requirements for these. I grow mine under 60%~65% shade with all my Onc's. It gets purple freckles and seems to put out lots of growths(6 since I got it).
