Review on 🌱 VIVOSUN 4 Inch 203 CFM ETL Certified Inline Duct Fan: Efficient Ventilation for Your Grow Tent by Danielle Hartman

I bought it for a small indoor grow tent and returned it immediately. Decided to spend a little more money and bought the AC Infinity device that I should have had. Not the best Vivosun product. Pros: - It actually has good airflow. - possibly suitable for hanging. - Super strong material. The block itself is heavy. Cons: - Not even a switch. Plug it in and let it work. - No power settings, wish there was at least a high/low switch. - Much louder than described and as stated by other reviewers. Not suitable for chic interiors unless it is in the attic or basement. Something rattled right out of the box.
