AeroStream H19: The Ultimate Humidity Solution for Large Collections

If you are serious about keeping Aroids, Ferns, and Calatheas happy, you know that consistent humidity is non-negotiable. The AeroStream H19 is a powerhouse humidifier designed to take the guesswork out of your environment.

Gone are the days of refilling small tanks three times a day. This unit is built for grow tents, dedicated plant rooms, and serious indoor jungles where stability is key to preventing crispy edges and promoting lush growth.

Why It’s a Game Changer

• Massive 19L Capacity: The huge 19L tank allows for long run times, meaning less maintenance for you. The tank is opaque to prevent light penetration, which stops algae and bacteria from growing inside. Plus, the low water alert ensures you never run dry unexpectedly.

• Smart & Connected: This is not just a humidifier; it is a smart device. Connect it to WiFi and the Vivosun app to monitor and control your humidity levels remotely. It integrates seamlessly with the Smart Grow System (SGS) to automate your environment based on real-time data.

• Precision Where It Counts: Unlike standard units that measure humidity at the base, the AeroStream H19 comes with an ultra-sensitive external probe. This allows you to measure the environment right at the canopy level for total accuracy.

• User-Friendly Design: No more heavy lifting. The unit features bottom casters for easy rolling and a top-fill design so you can refill it without bending over or disassembling the machine.

Customizable Airflow

Every setup is different, so the H19 comes with a complete accessory kit. Use the 5-way nozzle for broad coverage in a tent, or the flexible hose and extension pipes to direct mist into specific corners or hard-to-reach shelves.

Pro-Tip: Dial in Your VPD By using the external probe and the smart app features, you can maintain a specific Vapor Pressure Deficit (VPD). This is the "sweet spot" temperature and humidity ratio that allows your plants to transpire and uptake nutrients most efficiently!
