The G.A.S Enviro Controller V2 takes care of fan speeds for both AC and EC fans. And not only that, but it can also regulate ‘on’ and ‘off’ times for practically any piece of equipment in your grow room! For instance, lights (up to 1200w), heaters, humidifiers, and even pumps, can all be controlled using information gathered from the environment. This simplifies your set-up, making it easy to control your grow room and maintain a perfect environment from a single point.

Furthermore, the V2Enviro Controller has new features such as minimum and maximum day and night fan speed settings for enhanced control over your environment. And, it delivers the ability to calibrate your temperature and humidity sensor, automatic dimming function on the LED screens and new green LED lights which won’t disturb your plants' cycle.


The controller manages your grow room temperature and humidity by digitally controlling your fan speeds. The Enviro Controller V2 will automatically control fan speed for both AC and EC fans. As it comes with an inbuilt fan balancer, the V2 can control both your intake and outtake fans for your grow room. It is built to work perfectly with the Systemair Revolution EC and AC fan range.


The Enviro Controller V2 temperature and humidity sensor is easy to set up in your grow room and uses a thermostat to detect changes in the environment, regulating automatically to your pre-programmed parameters. This ensures there will never be any temperature fluctuations in your grow room. Humidity levels are also monitored and maintained with the humidity sensor. You can program day and night settings to keep your desired grow room climate and match up with when your lights cycle.


As well as controlling your fans, the Enviro Controller V2 comes with two extra fully programmable sockets that can control other environmental grow room equipment such as heaters, humidifiers, dehumidifiers and lights. Heaters can be set to come on whenever temperatures drop below pre-set levels.

For heaters, humidifiers and dehumidifiers, you can choose different settings for day and night time, so you’ll always maintain the perfect grow room environment. You can control most grow room equipment provided it doesn’t exceed 13 amps or 2,200 watts per exit. In the instance of grow lights, please don’t exceed 1,200 watts as they have a high start-up surge.

The V2 also has a dump feature for closed-loop environments. For a full how-to guide, please see our Enviro Controller Instructions.
