The US company Honeywell manufactures several different fan models that are well suited for use in the plant growing sector. The active ventilation of plants and the regular air exchange in indoor greenhouse areas are absolutely essential for plant cultivation. Depending on the size of the cultivation area and the plants, customers can opt for using pedestal, tower, desk or floor fans. All models allow adjustment of the air supply in various steps. The larger pedestal and tower units also feature programs and timers that provide full control of the timing, scale and airflow strength parameters for air distribution within the room. This is important because plants usually require more oxygen at night than during the day - yet excessively low temperatures should also be avoided. Honeywell's products provide optimal support for plant cultivation.
