The Enviro4 from Global Air Supplies is an environmental controller that automates and optimizes the major aspects of your grow’s environment. Equipped with four fully programmable outputs, you can easily control heaters, humidifiers, dehumidifiers, fans, lighting, and more — from a single, compact unit. It’s perfect for growers who want something that helps maintain stable conditions that improve plant health and boost yields. With high-precision sensors and an intuitive interface, it monitors temperature, humidity, and negative pressure in real time, adjusting equipment based on your custom setpoints. It also comes with day/night settings so you can fine-tune the climate based on your light schedule, as well as built-in safety features that help protect plants from extreme environmental fluctuations. If you need enhanced fan control, pair the Enviro4 with the AC-EC Digital Controller. It can also be integrated with the IHC SonicAir Pro Dual for humidity precision in dual zones.
