Overview

Our aim at Grow magic is to make growing your own crops as easy as possible. Fan controllers are just another way to make your time more efficient and the outcome more enhanced.

The purpose of fan controllers are to allow you to adjust your fan speeds in accordance to your current grow room needs. From time to time you will need to change the output of your fans to adjust temperature and humidity in the room and these controllers are ideal.

There are different types of controllers including Resistive type controllers and Voltage controllers. These fans work differently and produce different noise levels. Resistive types are known for being noisier as they work by slowing the fans down so you can change the balance of intake and extraction.

Voltage controllers are typically quieter and change the power output by using a variac to change the power supply to the fan.
