GAS Enviro4 (V4) Fan & Environment Controller | 4 Programmable Sockets | 26A Total

Take full control of your grow room with the Global Air Supplies Enviro4. This V4 controller regulates EC fan speeds and coordinates four programmable sockets so heaters, humidifiers/dehumidifiers, lights and more work in unison—not against each other. With day/night profiles, a dump feature for closed-loop rooms, and simple one-touch navigation, it centralises your environment control from a single hub.
