FAN-TASTIC 4A Hybrid Fan Controller | Silent Digital Temp Control + Fan Speed | Night Humidity Mode | Grow Room Climate Control

The FAN-TASTIC 4AMP Hybrid Controller is built to keep your grow space stable, quiet, and dialled-in. By combining mechanical and digital fan speed control, it drastically reduces fan noise while maintaining steady airflow and highly accurate temperature control—so your plants stay comfortable without the constant roar of fans.

Using modern digital temperature sensing, the controller delivers smooth, silent operation and is engineered to hold a constant temperature while ensuring controlled ventilation at all times. It’s ideal for growers who want better environmental stability (and less tweaking), especially during seasonal changes or overnight cycles.

Night-Time Humidity Control (Built for the “Lights Off” Spike)

When lights go off, plants can still transpire heavily, often causing a fast humidity jump that can invite mould or rot. The FAN-TASTIC Hybrid Controller includes a night-time humidity function designed to help remove excess moisture during the dark period—supporting cleaner air and more reliable results.
