Hi Charity. We grow this one here and from what I can tell, the less I do to it, the happier it is. It likes to grow out of its pot. We grow ours in a bark mixture with charcoal, perlite, and some coco husk. We water it once a week during the cooler months and twice a week during the warmer months. We fertilize with a weak mixture about once every two weeks (we used to do more often, but time and all.... lol). Light is just like the rest of our oncidium type orchids. And we grow in a greenhouse with lots of air movement. Good luck!
cheers,
BD
