Thank you two for the information. I knew that "smell" usually means stink in case of bulbophyllums but since I do not have a greenhouse I would not like my home smell like poop or "rotten death". :-)
However, I will give Wilbur Chang a try (if I will get it to bloom at all) hoping the smell won't be that powerful.
Thank you for updating regularly. I really enjoy sharing the thrill of the developing buds.
