FAQs

What size grow tent does this fan work best with?+

The VIVOSUN R6 with its 390 CFM airflow is ideal for grow tents up to 6x6 feet, such as those found in our 5' x 5' grow tents collection. For optimal air exchange, the fan should cycle the entire tent volume every 1-3 minutes.

How does the variable speed controller work?+

The integrated speed controller allows you to adjust fan speed from minimum to a maximum of 2550 RPM using a simple dial. This lets you fine-tune airflow for different growth stages, temperature conditions, or noise requirements.

What ductwork size do I need for installation?+

This is a 6-inch inline fan designed to connect to standard 6-inch ducting. It pairs perfectly with accessories like the VIVOSUN 6" Duct Air Carbon Filter for complete odor control. The removable duct ends with locking tabs make connection quick and secure.

Can this fan handle continuous 24/7 operation?+

Yes, the R6 is designed for continuous operation in ambient temperatures up to 104°F (40°C). The energy-efficient 67W motor and durable plastic construction ensure reliable performance during extended use.

How can this fan improve my grow room's climate?+

Proper ventilation is key to preventing issues like high humidity and stagnant air. This fan helps you maintain a healthy environment by exhausting hot, humid air and pulling in fresh air. To learn more about perfecting your setup, check out our guide on grow room temperature and humidity.

Is this fan compatible with smart controllers?+

While this model comes with a manual variable speed controller, many growers integrate fans like this into larger automated systems. For advanced control, you might consider a smart controller like the Vivosun GrowHub E42A to manage your entire grow environment.
