Fan Controllers

Seasonal changes in temperature mean that you won’t always need to run your extractor fans at full speed. Here at GroWell, we offer a wide variety of fan speed controllers to help you perfectly balance the intake and extraction rates in your grow room.

There are a number of ways of adjusting the speed of an extractor fan, with the cheapest and most prevalent method being to use a resistive type of controller. These controllers slow the fans using increased resistance and represent an incredibly budget friendly option for adjusting your extractor fan speeds.  

An alternative fan control method available to indoor gardeners involves voltage controllers, which use a variac to alter the actual power supplied to the fan. These controllers are much more heavy duty and do not create any additional fan noise in comparison with resistive type controllers. A more expensive option, these fan controllers generally suit more experienced users.
