Little or no sun
Bright daylight is sufficient to keep some plants healthy.
Temperature
Any figures that are quoted are for daytime. Night temperatures can usually drop about five degrees. (Cool is 40 to 60 degrees; moderate, 50 to 70 degrees; warm, 60 to 80 degrees.)
Humidity
This is noted if the plant needs more than average humidity (50 per cent).
Soil
The plant may prefer a potting mixture that is humusy, extra-rich in organic matter; average, like the potting soil I have described on other pages; sandy, with an extra ration of sand, or a similar substitute. Or it may be epiphytic and grow in some suitable medium such as osmunda fiber or sphagnum moss.
Dry
Let the soil dry thoroughly before watering.
