VIVOSUN GrowHub E42A Grow Room Environment Controller

Every Device in the Room, One Set of Rules

An all-in-one environmental controller that brings lights, fans and humidifiers under a single platform instead of a wall of separate timers and switches. The GrowHub E42A monitors temperature, humidity and VPD live, then automates equipment against those readings, with dynamic timers, ramping and day/night cycles plus climate-based triggers. App connectivity means you can watch the room and change settings from your phone, and the system is expandable, linking up with other Vivosun Smart Grow devices as you add them. Everything runs through one clean interface, so programmes can be tailored to the stage the crop is at and left to run.

Key Benefits

• All-in-one control of lights, fans and humidifiers from a single hub
• Live temperature, humidity and VPD readouts, so decisions come from data not guesswork
• Dynamic scheduling with light ramping, day/night cycles and climate triggers
• Automatic fan speed response to real-time climate readings
• Remote app access with alerts and on-the-fly adjustment from anywhere
• Expandable and modular, linking further Vivosun Smart Grow lighting, fans and sensors

A Room That Drifts Every Time You Are Not Watching

Manual timers cannot react. Temperature climbs mid-photoperiod and the canopy stalls, humidity spikes at lights-off and buds finish airy, then airflow sits wrong and you get slow growth for weeks before spotting it. Tying extraction, circulation and humidity to live readings means the room corrects itself the moment it drifts.

How to Use

• Mount the controller in or near your tent, with the sensor at canopy height
• Connect equipment, plugging compatible lights, fans and sensors into the hub
• Run the setup wizard from the on-screen prompts at first power-on
• Programme schedules and climate triggers via the display or the smartphone app
• Set day and night targets separately, then monitor live data as the crop moves through veg into flower
