The Variispeed Fan Speed Controller is a cost effective and simple way to manually adjust the airflow of your intake or extraction fan to help your grow room maintain its optimum temperature at all times.

Setting up the Variispeed Fan Speed Controller couldn’t be easier, just plug your fan into the device, then plug the device into the power supply or timer and that’s it, there’s no need for complicated equipment or probes to monitor the temperature.

Adjusting the airflow on the Variispeed Fan Speed Controller is simply done using the dial on the front, turn it down to reduce the airflow, ideal when the ambient temperature is cooler, or when lights are off, meaning warm air will stay in the grow room longer, or increase the airflow on hot days so warm air will be exchanged quicker and both will help you to maintain a perfect temperature in your grow room, all year round.
