Sale price£350.00



The Envrio4 controller, created by Global Air Supplies, offers full control over your environment, enabling you to enhance your grow. It can manage EC fan speeds and set 'on' and 'off' times for almost any equipment in your grow room through its four programmable sockets. This streamlines your setup, simplifying the control of your grow room and maintaining an optimal environment from one singular point.

The Enviro4 is a convenient solution for managing all your growing equipment from a central location. It comes equipped with four programmable sockets that can manage up to 26 amps of power, twice as much as the previous version, Enviro v2. With the Enviro4, you no longer need to use two separate controllers, which could lead to conflicting instructions. Moreover, the temperature sensor probe is easily replaceable with the help of a connector socket located on the unit's exterior. By using the Enviro4, your equipment can work seamlessly together to create an ideal environment.


Your grow room's temperature and humidity can be effectively managed through the use of the Enviro4 Controller, which digitally adjusts your fan speeds. This controller is capable of automatically controlling the fan speed of EC fans and can manage both the intake and outtake fans in your grow room. It is specifically designed to work seamlessly with the Systemair Revolution EC fan range.


Setting up the Enviro4 temperature and humidity sensor in your grow room is a breeze. With its advanced thermostat, it can detect environmental changes and automatically regulate them based on your pre-set parameters, ensuring that there are no temperature fluctuations. Additionally, it comes equipped with a humidity sensor that continuously monitors and maintains the humidity levels. You can customize day and night settings to create the perfect grow room climate. Moreover, the Enviro4 boasts an upgraded probe that is easily replaceable.


With the Enviro4, you can easily manage not only your fans but also up to four programmable sockets to regulate other vital grow room equipment such as heaters, humidifiers, dehumidifiers, and lights. The device enables you to configure heaters to activate when temperatures dip below your desired levels. Additionally, for heaters, humidifiers, and dehumidifiers, you can customize various settings for day and night to maintain the optimum grow room conditions. The Enviro4 can handle most grow room equipment, provided it doesn't exceed 2,200 watts per outlet. For grow lights, avoid surpassing 2,400 watts (distributed across all four sockets) to avoid start-up surges.
