I've had this little guy for some time now with not a bloom. I tried repotting, tried changing light, tried changing watering regime, but nothing worked. I did get a couple side shoots and roots that started out then dried up, but no blooms. I recently moved it down into the Orchidarium under pretty bright light (1800+ FCs for 12 hours) and high humidity (90+ %) and right away (within 2 weeks) one of the stalled side buds started growing. At first it looked like another side shoot, but then it started to swell and was obviously a flower bud. Two days ago it opened fully (was all white and closed in the morning and then fully open in late afternoon). It smells like an Easter Lily at night.

That's a 3" pot. It's planted in pure, fine fir bark.
Thanks for looking.
