Did you know: the best grow room temperature is 24^oC - 28^oC (day/lights on) and 22^oC - 23^oC (night/lights off)

Control your temperature with the speed of your fans - all you need is an SMSCom controller.

Your intake and extractor fans will speed up if your room needs cooling, or slow down if it needs heating (temperature sensor included).

Don't worry about air exchange - you can set minimum and maximum fan speeds.

It's easy to set up! No hard wiring's needed. Just plug your fans in, then set your target temperature, min speed & max speed using the 3 dials. It's that simple!

If you need a longer power cable, you can quickly plug it into your controller's IEC socket (like what lots of kettles have!).

For safety, each controller has a replaceable fuse.

Overall, your controller can handle a total 4.5 Amps. Any combination of RVK Extractor & Intake Fans will work perfectly!

We recommend

Your controller can handle a total 4.5 Amps. It's perfect if you have an RVK Extractor & Intake Fans.

You can even use the controller with some of the larger acoustic fans, but we generally recommend upgrading the controller. Start a live chat or visit your local store for more advice.

Never try using this controller with a circulation fan - they have their own speed controllers.
