Purchase several ghost orchid seedlings. It's almost a given that someone trying to grow the orchids for the first time is going to kill a few, but this will also allow you to learn how to keep an observant eye on the seedlings and troubleshoot a problem before it becomes fatal.
Plant your orchid in a terrarium. This will give the orchid two of the major components it needs for a successful growth cycle; the humidity must be very high, and the air around the plant must be still.
Use only distilled water on your ghost orchid, as the chemicals in tap water can damage or kill your delicate plant. You should have a layer of moss in the terrarium; make sure this dries out fairly well between waterings. Don't keep the plant in standing water.
Make sure you keep the humidity constantly high, otherwise the plant will shrivel and dry up. You can spray the air inside the terrarium with some of the distilled water, but make sure you don't keep the plant standing in water, as this can rot the roots. Ghost orchids require a delicate balance.
Place your orchid in a spot where it can receive moderate sunlight at first. Once it has begun to grow and you are trying to encourage it to flower, you can move it to a place with full sunlight.
