I’m going to bump this up because I want to see if, hopefully, anyone else responds.
I’ve only had mine about a year and it is chugging along beautifully. No blooms yet, but I’m not sure if it old enough. Ive been giving mine more moderate light, it’s been hanging out between my Dens and some Catts where I’m sure it gets a bit of shading. Most of the leaves and pbulbs are growing vertical with a few at more of a 45degree angle. I don’t have any reddish color in my leaves both the light levels I am giving it. Have you looked at the Chadwick website?
Cattleya luteola They list it as pretty adaptable to most light levels, as long as it is kept warm
