Is this a dancing lady orchid(oncidium)? If so, they require
high light with little if any direct sunlight. To increase
humidity around the plant, use a tray thats at least 4-5
inches high, place gravel in the tray (3 -4 inches worth)
then keep about an inch of water in the gravel at all
times. Your orchid will sit on the gravel, but not directly in the water. This will increase humidity.
