Vivosun – Aerostream UO75 USB Humidifier

VIVOSUN AeroStream U075 750mL USB Humidifier – Compact Grow Tent Humidifier

Keep humidity under control without taking up valuable grow-tent space with the VIVOSUN AeroStream U075 USB Humidifier. Compact, quiet and easy to use, this 750mL humidifier is designed specifically for small grow tents, propagation areas and compact indoor gardens where maintaining consistent moisture levels can make a real difference.

The AeroStream U075 features two mist modes — continuous and intermittent — allowing you to choose the level of humidification your plants need. Continuous misting can run for up to 18 hours, while intermittent mode extends operation to approximately 28 hours, reducing the need for frequent refills.

With a mist output of up to 50mL per hour and operating noise below 28dB, the U075 provides gentle, low-noise humidification without becoming a distraction. Its compact footprint makes it particularly useful inside smaller grow environments where space is limited.

Safety is built in with an automatic low-water shut-off, which stops the unit when the water level becomes too low. The memory function also remembers your last selected mist mode and automatically resumes it when powered back on.

The AeroStream U075 can also integrate with the VIVOSUN VGrow Smart Grow Box, allowing humidity management through the VIVOSUN app when connected to a compatible VGrow system. It is not designed for use with the GrowHub E42A.
