VIVOSUN AeroStream H19 – 19L Smart Ultrasonic Humidifier

The VIVOSUN AeroStream H19 is an industrial-grade, intelligent humidification system designed for large-scale grow rooms, greenhouses, and expansive living areas. Featuring a massive 19-litre opaque water tank, the H19 is engineered to provide days of continuous, whisper-quiet moisture without the need for constant refills. Its advanced ultrasonic atomizer and high-performance fan work in tandem to deliver a fine, cool mist that balances environments quickly and efficiently.

Equipped with an external high-precision temperature and humidity probe, the AeroStream H19 doesn’t just put out moisture—it monitors the specific micro-climate of your plant canopy to provide targeted, automated adjustments. As a core component of the VIVOSUN Smart Grow System (SGS), the H19 can be fully integrated with the Vivosun App, allowing you to sync it with your GrowHub controllers and execute complex grow recipes for professional-tier climate stability.

Features and Benefits

• Massive 19L Capacity: The high-capacity opaque tank minimizes maintenance and prevents light penetration, reducing the risk of algae or mineral contamination.
• Precision External Sensing: Includes an ultra-sensitive external probe that provides real-time, targeted humidity and temperature data to the internal controller.
• Whisper-Quiet Ultrasonic Tech: Utilizing next-gen atomizers, the H19 provides powerful output with minimal noise, making it suitable for bedrooms and quiet offices.
• Smart App & SGS Integration: WiFi-enabled for remote monitoring and control via the VIVOSUN App. Seamlessly integrates with GrowHub E42/E25 to automate humidity based on growth stages.
• Top-Fill & Ergonomic Design: Features a top-mounted control panel for easy access and a large top-opening for mess-free refilling.
• Effortless Mobility: Equipped with heavy-duty bottom casters and side handles, allowing you to move 19kg of water with ease across your grow space.
• Versatile Output Options: Comes with a comprehensive accessory kit, including a 5-way nozzle, elbow nozzle, and flexible hose for custom mist direction.

• Living Rooms & Large Offices: Helps prevent dry skin and respiratory issues in air-conditioned or heated environments.
• Tropical Plant Collections: Perfect for indoor “jungles” that require a constant, stable humidity floor.

Usage & Maintenance

To ensure the longevity of the ultrasonic atomizer, it is recommended to clean the base of the unit once every two weeks to remove mineral buildup. Use the “Intelligent Constant Humidity” function to set your desired RH% (Relative Humidity); the H19 will automatically ramp its output up or down to maintain that specific level, saving water and energy.

FAQs

Can I use this humidifier to dispense nutrients or foliar sprays?
No. The H19 is designed for clean water only. Adding oils or nutrients can damage the ultrasonic transducer and void the warranty.

Is it compatible with the E42A GrowHub?
Yes, as a part of the SGS ecosystem, the H19 can be paired with any VIVOSUN Smart Controller to participate in automated grow schedules and triggers.

How long does a full tank last?
Depending on your target humidity and room size, a full 19L tank can last between 2 to 5 days of continuous operation.

Can I extend the mist into a grow tent while the unit sits outside?
Yes. Use the included flexible hose and straight pipe to direct the mist through a tent port while keeping the main unit and water reservoir outside for easier refilling.
