Description
xThe VIVOSUN G4 4" inline fan pairs a high-efficiency 195 CFM mixed-flow EC motor with the GrowHub E42A+ smart controller to deliver quiet, automated ventilation and climate monitoring for indoor gardens.
If you need dependable air movement, precise environment tracking, and app-based automation in a compact package, this VIVOSUN bundle combines a powerful 4" inline fan with a smart controller and probe. It was designed for indoor growers who want consistent airflow, energy savings, and the ability to create stage-specific schedules while monitoring temperature and humidity from anywhere.
How does the G4 fan improve airflow while staying quiet?
The G4 uses a mixed-flow impeller driven by an EC motor with PWM control, which produces strong long-distance airflow while operating at lower noise levels. Expect airflow up to 195 CFM with acoustic performance down to about 39 dB under normal conditions.
- EC motor for higher efficiency and smoother speed control
- Mixed-flow design for sustained static pressure and duct performance
- Noise reduction measures to minimize vibration and sound
- Compact 4" diameter suits small tents, ducts, and tight spaces
What smart features does the GrowHub E42A+ controller offer?
The GrowHub E42A+ centralizes management of compatible devices, enabling automated schedules, remote adjustments, and environmental triggers. Use the app to run grow recipes, change fan speeds, and create custom responses based on temperature or humidity readings.
- Wi‑Fi app control for remote monitoring and adjustments
- Preset stage-specific schedules for seedlings, veg, and bloom
- Auto-triggers to start or modulate devices by thresholds
- Expandable ecosystem to add lights, pumps, sensors, and more
How does the included probe help maintain a stable grow environment?
The bundled temperature and humidity probe streams real-time data to the controller and app, letting you view inside vs. outside tent conditions and calculate VPD for better crop management. Accurate environmental feedback enables the controller to adjust devices automatically for consistent conditions.
- Combined temp and humidity sensing for holistic readings
- Real-time data visible in the mobile app and dashboard
- Supports VPD calculations to assist crop staging decisions
- Enables event-based automation like fan speed changes
How durable and adaptable is this fan and controller setup?
The G4 fan features a corrosion-resistant metal housing and a mountable base for wall installation, saving floor space and improving layout flexibility. Its rugged build and wide compatibility make it suitable for grow tents, greenhouses, hydroponics, attics, and small HVAC ducts.
- Sturdy metal construction resists corrosion and wear
- Mountable base for secure wall or frame installation
- Compatible with common ducting and ventilation accessories
- Designed for both hobby and small commercial setups
Who is this for: The VIVOSUN G4 4" 195 CFM inline fan and GrowHub E42A+ smart controller are aimed at indoor growers who want a compact, quiet ventilation solution with modern automation.
