I would say these need more light than Miltoniopsis which are more like Paph and Phals. These are fairly high light plants that are quite a yellowish green when given optimal light. They can take heat better than Miltoniopsis also. I had one that bloomed regularly before I sold it. I did question that I had a pure species and I didn't like that it had really short and crowded spikes, unlike some I see in bloom in pics, so I sold it.
My division came from an old time member of our OS who won an AM/AOS and named for his wife. I mentionned to him I had this division but was concerned I may not be caring for it correctly as the leaves were more yellow than I anticipated. Said this was usual and I've since read it to be the case. Had mine outside all summer but bright light only.Lovely darkish purple blooms and fragrant(licorice).
IDK, Mine is under the T-5s about 6 inches from the bulbs, 10 hours a day. No burn, light green, not yellow. When I first got it, I thought it might be too close, but it doesn't seem to hurt it any.
I haven't grown this one..but I did see some this fall at the local club sale. They indeed were crazy yellow and some were in bloom...so yes,pretty high light seems best culture.
