Who This Is For
- You are automating climate controls because checking humidity manually is impossible when you are away from the garden.
- Upgrading to an EC motor is your move because your current AC fan vibrates through the entire structure.
- You are adding a dedicated intake fan because your tent walls are sucking in too hard from the main exhaust alone.
What We Found
- The 28 dB rating is accurate, making it quiet enough to run in a living space without a muffler.
- The E12 controller responds faster to humidity spikes than many expensive stand-alone sensors.
What Users Say
- Users who switched to the E12 say they stopped checking their tents every hour to monitor the climate.
- Growers in small spaces say the 4 inch footprint leaves more room for plants without losing power.

FAQs
The AeroZesh G4 uses an advanced EC (Electronically Commutated) motor controlled by PWM (Pulse Width Modulation). This allows for precise speed adjustments, significantly reducing energy consumption to just 20 watts while maintaining powerful airflow and quiet operation compared to traditional AC motors.
The E12 controller provides ten programmable fan speeds, three ON/OFF cycle modes for automation, and a backup memory that saves your settings during power outages. Its key feature is the environmental probe, which enables automatic fan speed adjustments based on real-time climate data.
The included environmental probe continuously monitors temperature and humidity. The E12 controller then uses this data to automatically increase or decrease the fan's speed to maintain your target climate, ensuring a stable environment without constant manual adjustments. You can learn more about maintaining the perfect climate from our grow room temperature and humidity guide.
With 195 CFM of airflow, the AeroZesh G4 is ideal for effectively ventilating small to medium-sized grow tents, such as 2'x2', 2'x4', and 3'x3' models. It's a perfect ventilation solution for a setup like the VIVOSUN Smart Grow Tent Kit - 2 Plant G4.
The AeroZesh G4 operates at just 28 dB. The combination of the EC motor and steel construction minimizes noise and vibration, making it ideal for use in residential areas where quiet operation is essential.
Yes, the system is designed for easy upgrading. By connecting it to a VIVOSUN GrowHub controller like the E42A, you can unlock remote monitoring, scheduling, and full automation through the VIVOSUN App on your smartphone or tablet.
