Yvan is correct. They need pretty high humidity and constant air movement. Mine is on a mount and in the tank at 99% humidity and constant breeze 24/7. It is in multiple spike right now. Will post pics when in full bloom. Here is was last year:
This year, the plant has covered that cedar shingle and there are more than 10 spikes.
Constant wetness is good, but they do not want to be stagnant. I water daily with dilute fertilizer and the breeze sort of dries down the root mass. Most of the roots are exposed so total dryness isn't good for them. Hope this helps.
