I had a Medinilla magnifica about a year ago that I killed due to overwatering and putting the plant in too large a pot. Not a good combination. The plant was potted in potting soil. Since I think these flowers are as beautiful as any orchid (I know that statement may get me permanantly banned from this board

), I have decided to try again and have just ordered another plant.
I was wondering if anyone has any experience growing this plant and what medium you grew it in. I read that they are epiphytic, so I am thinking about using CHC with a little charcoal and LECA thrown in. Any thoughts or suggestions?
