How to Grow Orchids in Humid Enclosures
- 1). Open the enclosure's vents to release stagnant moisture. Leave the enclosure's vents open during the daytime when the sun provides high levels of heat. Close the vents at night to prevent the humidity level from dropping below 60 percent.
- 2). Place an oscillating fan in the enclosure, and set the fan to a low to medium setting to push the air throughout the space.
- 3). Limit watering the orchids to once a week when humidity levels are high in the enclosure, as the orchid receives plenty of moisture from the air without the need for frequent watering.
- 4). Set the orchid near the south- or east-facing side of the enclosure to ensure it receives adequate sunlight. Orchids require at least 12 hours of daily sunlight to grow, and the direction of the light affects the quality of light received.
