repotting trichopilia

[charity]

so, I'm looking to repot trichopilia suavis after it finishes blooming but I am hesitant because I did so last year and I want him to grow bigger and I'm not sure the trauma of repotting is going to help. I need to do this this year because he grew in a direction I didn't expect and he is against the pot on the wrong side. But, in the future, should I repot him yearly or go 2 or 3 in between for best growth? Do you recommend 100 percent fine bark and lava rock or some moss ??? Also thinking of switching to plastic rather than ceramic with holes because I don't think he is damp enough and I want to help retain moisture. He hasn't grown as much as I'd like in the year I have had him. Thanks for your opinions and help!

These is very interesting species flower exactly likes a trumpet beautiful white, combination of charcoal and fine bark is more then enough, plastic pot to me is also acceptable it's depend on your choice.
