I grow it outside, it's fine. I have read that it needs to be a little drier in winter but I don't give mine any special treatment and it does fine. Needs to grow hanging since spikes are pendant. I have it in a basket with medium bark, so well-drained. One thing to remember about the spikes - they are pendant but not soft... if you try to "adjust" them they're likely to snap off because they are quite rigid. I think it's one of the prettiest orchids.
