Vivosun AeroStream H19 Humidifier Intelligent 19L

Create the perfect growing environment with the VIVOSUN AeroStream H19 Intelligent Humidifier, a high-capacity environmental control solution designed specifically for grow tents and indoor cultivation spaces. Featuring a massive 19L water reservoir, smart app connectivity, and precision humidity monitoring, the H19 makes maintaining optimal humidity levels effortless throughout every stage of growth.

Powered by an advanced ultrasonic atomiser and high-efficiency fan, the AeroStream H19 delivers up to 1300ml/h of mist output while operating quietly at just ≤46dB. The included external temperature and humidity probe provides accurate environmental readings directly from your grow space, allowing the humidifier to respond more precisely than conventional room-based units.

Designed with growers in mind, the H19 integrates seamlessly with the VIVOSUN Smart Grow System, enabling remote control, environmental monitoring, custom automation, and real-time notifications through the VIVOSUN app. Adjustable mist levels and intelligent humidity control help maintain stable growing conditions while reducing the need for constant manual adjustments.

The large 19L opaque water tank minimises refills while helping prevent light exposure and contamination. Convenient top-fill access, built-in wheels, carrying handles, and multiple mist distribution accessories make the AeroStream H19 suitable for everything from small grow tents to larger cultivation rooms. With up to 67 hours of runtime per fill, it provides reliable humidity control with minimal maintenance.
