Mine grows in a black net pot with some different types of moss in it. I never repotted it when I got it. It is growing along with my vandas. Lots of sunlight. It gets fert. when everything else get it too. The color of the leaves are more yellow than green so if your leaves are green it can use more sunlight. Hope this helps
The sunlight is a good point. Last year it got quite yellow, but I think I've had it shadier this year so I need to put it out to get more light I think.
