Massive 9L Capacity for Extended Automation
Keep your indoor garden perfectly humidified without constant refills using the VIVOSUN AeroStream H09 Intelligent Wi-Fi Humidifier. Boasting a massive 2.38-gallon (9-liter) water tank, this heavy-duty ultrasonic humidifier delivers continuous, fine moisture output for days on end.

Intelligent Sensor Automation & VPD Tracking
Take the guesswork out of plant transpiration. The AeroStream H09 comes equipped with an external, high-accuracy temperature and relative humidity sensor probe.

Built-in 2.4 GHz Wi-Fi connectivity allows you to pair the device directly with your smartphone app. Program custom day-and-night humidity schedules, establish automatic triggers, and receive instant mobile alerts if water levels run low or if your tent climate leaves its safe threshold.

Smart Humidity Control for Faster Growth & Healthier Plants

The VIVOSUN AeroStream H09 Intelligent Wi-Fi Humidifier has been purpose-built for indoor growers who want precise humidity control without constant manual adjustments. Featuring a 9-litre water tank, an external temperature and humidity sensor probe, and seamless integration with the VIVOSUN Smart Grow System (SGS), the H09 automatically maintains your target humidity to create the perfect environment for propagation, vegetative growth and early flowering. Healthy humidity levels reduce plant stress, encourage stronger root development and support faster, more vigorous growth.

Unlike household humidifiers, the AeroStream H09 is designed specifically for grow tents. It offers 1% humidity adjustment, intelligent constant humidity mode, whisper-quiet ultrasonic misting, a top-fill design, low-water alerts and smart Wi-Fi control through the VIVOSUN App. Whether you're growing tomatoes, peppers, herbs or leafy greens, the H09 helps maintain stable VPD and humidity, allowing your plants to thrive while reducing the need for daily intervention.

Yes. The top-fill design allows quick and convenient refilling without dismantling the unit, making day-to-day maintenance much easier.

Maintaining the correct humidity supports healthy transpiration, reduces plant stress, improves nutrient uptake and helps seedlings and young plants establish strong root systems. Stable humidity also makes it easier to maintain an ideal VPD throughout the growing cycle.

The AeroStream H09 is ideal for hobby growers and serious indoor gardeners looking for reliable, automated humidity control inside grow tents. It's perfect for anyone building a smart growing environment using the VIVOSUN ecosystem.
