Thanks for the info Geoff. They are in a heated greenhouse but over the winter the temps are kept below house temps. so I think I can give it the cool growing quite well. They get quite high light and I try not to over water in the winter with cooler temps. I am going away for 3 weeks so maybe one of them will have a spike when I return! The other possibility is our house sitter could kill everything, but I sure hope not. He has instructions If I ever get a bloom I will post a photo.
