As the seasons change, so do your fan speed requirements. We offer a wide variety of fan speed controllers to help you perfect the balance of intake versus extraction rates in your grow room.
There are a number of ways of adjusting the speed of an extractor fan. The cheapest and most prevalent method is to use a resistive type controller. These controllers slow the fan by increasing resistance. They represent an effective and 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 more heavy duty and do not create any additional fan noise in comparison with resistive type controllers. Being the more expensive option, these fan controllers generally suit more experienced or large-scale growers.
