Rosie;
I grow mine under lights along with my Masdies and give them the same conditions. They're great little plants and you definitely should get more.
Yours in the photo looks like it got a bit too much light. I can't explain why the flower has it's head thrown back like that.
The guy I got mine from had his in the darkest part of his greenhouse. He set up a series of rain gutters facing north like rungs on a ladder with his higher light plants up top and his Masdies, Restrepias, and other Pleurothalids in the lowest 1/4 to 1/3 of this setup.
Cheers.
Jim
