Hi Ana, Here is a searched url for you.

I have mine in the shadier end of my green house hanging up with a breeze
blowing on it.
I think the trick for these guys is for them to be in a small pot, I noticed
mine blooming
profusely once it filled the 3" pot.

Hello,
I have bought a psichopsis papilio "blooming size" with 3 pseudobulbs
and a new growth. How much pseudobulbs are necessary in order that he
blooms?. He'll bloom when he finishes the new growth?
