I couldn't get mine to bloom either for three or four years and then an OS member brought hers to a meeting to show off the blooms. I asked about the winter rest and she said, "What winter rest?" She just watered it normally through the winter. Last year, I didn't give it a rest and boom...blooms. It might be that the air is already drier in the winter and that mine is potted up in red lava rock and a Vanda basket so it dries quickly but I was impressed.
This year, mine decided to put out a second set of growths this autumn, under the T5HO lights so I am not sure what will happen. It will be fun to see.
These do like Cattleya light so you might want to increase the lighting. Good luck!
