I bought 10 last year and I'm still waiting for even one to bloom and four of them are definitely bloom size. I am dying to know if any of them will be the elusive yellow or orange. I don't see why you can't grow them outside in the summer, I have a bunch that grow outside all year and they don't have a problem with the heat or the rain. I will agree that moss is better than bark for growing them. I don't even change the moss when I repot because the roots are so fragile, you will lose more cleaning them off than just leaving the old moss.

My Zygos get spotty leaves when they go out for the summer. My Oncidiums also do this.
