It is mounted on a piece of wood along with some sphagnum. It gets phal-like light, temps are around 14-16oC with a bit less (~3oC) in the night for the winter and I water it every other day (when it was more cold I did not mist it at all fro 3- days...). Humidity stays around 70% (or a bit more).
When I got it in late summer, I watered it every day and most of the times twice per day. But it stayed the same since them. 1-2 leaves have dropped. It is showing new growths now though, so maybe this is an improvement....?
