The new Hybrid Controller Pro combines mechanical and digital fan speed control to drastically reduce the noise from your fans, and also provide a perfectly controlled environment to your crop. 

Using the latest digital temperature sensing technology, the result is a completely silent, twin fan speed controller with highly accurate temperature control. These units have been engineered to maintain a constant temperature and controlled airflow at all times, whilst also reducing nighttime humidity. 

The Hybrid Pro features a nighttime humidity function that will remove excess humidity. When lights turn off, plants are still transpiring quite heavily and this can cause a sudden spike in humidity (leading to problems with rot or mould). The SMSCOM Pro units will remove this excess humidity during the dark period.
