What is the name of your Neofinetia? You must be doing something right, as the picture shows your plant is in bud. You can pot Neofinetias like any other orchid. But the reason why you see them in high mounds of sphagnum moss is that is the traditional Japanese way of growing them. As mentioned earlier, if your plant is in moss, water it when the moss is dry feeling or "crispy". I water my plants in the sink. I do not mist these plants, especially when they are in bud, as this seems to cause bud blast.
