VIVOSUN AeroStream H09 Intelligent WiFi Humidifier

The AeroStream H09 connects via WiFi to the VIVOSUN app, allowing it to communicate with the entire Smart Grow System (SGS). When paired with a Vivosun GrowHub E42A Controller, you can automate your environment by setting custom grow recipes that control the humidifier, lights, and fans in perfect sync.

Phantom Mode turns off the humidifier's display screen during operation. This is crucial for photoperiod-sensitive plants that require complete, uninterrupted darkness during their night cycle. Even small amounts of light can cause stress and disrupt flowering, so Phantom Mode ensures your plants' environment remains perfectly dark.

The refill frequency depends on your target humidity level, the ambient room conditions, and the size of your space. However, the large 2.38-gallon (9L) capacity is designed for extended operation, often lasting several days without needing a refill, which is a major convenience for busy growers.

Yes. As long as the humidifier is connected to your home WiFi network, you can monitor and control it from anywhere using the VIVOSUN app on your smartphone. This allows you to check humidity levels, change settings, and receive alerts remotely.

The AeroStream H09 is ideal for small to medium-sized spaces. It performs exceptionally well in tents up to 4'x4' grow tents. For larger spaces, you might consider using multiple units or a larger capacity commercial humidifier to ensure even coverage.

An external probe provides more accurate readings of your grow space's actual conditions, away from the direct influence of the humidifier's mist output. This prevents the unit from short-cycling and ensures it runs based on the true ambient humidity, leading to a more stable and precise environment for your plants.
