Provide some humidity for the plant; most do not like very dry environments.
Humidity measures the amount of water vapor circulating in the air. Orchids need high humidity (50%-75%) all the time. Plant leaves have microscopic openings that “breathe in” water vapor and oxygen. Even during winter dormancy, orchids still want moderate humidity around their leaves and roots. As temperatures rise, orchids need increasing humidity to cope with the heat. Direct sun can heat up an area very quickly; the afternoon sun especially can dry out the air. Wind also dries out plant leaves, and even though they enjoy the air movement, this must be balanced with high humidity.
