VIVOSUN Inline Fan 6-Inch

Stale air and uneven temperature can make an indoor growing space harder to manage. The VIVOSUN G6 inline fan is designed to move air through grow tents, greenhouses, and other indoor spaces, with adjustable speed and cycle settings to shape its ventilation around your setup.

Its 388 CFM airflow and included E12 controller give you more control than a basic fixed-speed fan. The listing does not specify room-size guidance, though, so airflow alone won’t tell you whether it’s the right fit for your space.

Key specifications

The G6 is a 6-inch inline fan with a mixed-flow design, an EC motor, and PWM speed control. Its E12 controller offers ten fan speeds and three on/off cycle modes. A memory function retains the last speed setting after the fan is switched off and back on, which can save you from resetting it during routine use.

The product description lists airflow at 388 CFM and operation at 32 dB. Treat the noise figure as a stated specification rather than a guarantee for every installation, the listing doesn’t provide measurement conditions. The fan is also described as suitable for temperature and humidity management, but it does not specify sensors or automatic temperature-based adjustment with the included controller.

Who it’s for

This setup is aimed at indoor growers who want to adjust ventilation rather than leave a fan running at one fixed speed. For example, you could set a lower speed for regular air circulation in a grow tent, then use a cycle mode when you want the fan to switch on and off as part of your routine. It suits you if you want adjustable airflow and scheduled cycling from the controller included in the product description.

The listing also mentions upgrading to an E42A multi-device controller or integrating a GrowHub controller with an app system for remote automation. Those are described as upgrade paths, not features to assume are included with the G6. Without having tried it, the most useful buying distinction is the control approach: this package is more flexible than a simple fixed-speed fan, while app-based, multi-device control calls for additional hardware.

Everyday use

The G6 is described for grow tents, greenhouses, and indoor spaces, and its power cord is intended to make installation easier. In a tent, an inline fan can serve as the ventilation unit in a broader airflow setup, speed adjustment and cycling let you change how it runs without treating every situation the same. The product page doesn’t state dimensions, ducting details, or a recommended space size, so those specifics may matter when planning an installation.

Before you decide

Does the fan include a speed controller? The product name and description identify an E12 controller with ten speed settings and three cycle modes.

Can it be controlled through an app? App-based remote control is described with a GrowHub controller. The listing presents that as an integration option, not a confirmed included feature.

Is the 32 dB figure a guarantee in a grow tent? It is the stated operating noise figure, but no measurement conditions are given. Your installation may not match the conditions behind that specification.

When it makes sense

Choose the G6 if you need an inline fan for an indoor ventilation setup and value adjustable speed, cycle modes, and retained speed settings. Not the best choice if you need a complete app-controlled system in the package, or if you need confirmed sizing guidance before choosing a fan: the listing gives airflow, but not a recommended room size or detailed installation dimensions.
