Orchids need proper air movement, humidity, and light to thrive. At its highest level, the fan operates at 22 cfm and can be reduced to less than 10 cfm. The rheostat allows the air movement to be adjusted. I often change my air movement randomly, turning it down at night as occurs for the plants in nature. Before I water, I often speed up the air movement to make sure plants are adequately dried out. I also like higher speeds after I water with a quart spay bottle. When I am away, I leave the fan on at half-speed. Nature’s air movement is highly variable, so I just change the airflow a bit when I think of it. This very quiet fan is not on a timer and is meant to run 24 hours a day. It is rated to last for 50,000 hours minimum. The fan is include in both the standard and premium case.
This little orchid blossom is from last winter in my first prototype case.
