The Vivosun AeroStream is a compact 750ml USB-powered ultrasonic humidifier built for small grow tents, propagation areas, and seedling spaces where dialling in humidity makes a real difference to early-stage plant health. It runs whisper-quiet, mists continuously or intermittently, and plugs straight into any USB power source — no separate power adapter required. A practical, low-fuss solution for growers who need humidity control without the footprint or the price tag of a full-size unit.
Specifications
- Use distilled or filtered water in ultrasonic humidifiers — tap water with high mineral content leaves white residue on leaves and surfaces over time.
- Position the mist outlet so vapour disperses into the air rather than pointing directly at plants or cuttings at close range.
- Clean the tank and ceramic disc every 1–2 weeks with a small amount of white vinegar to prevent mineral build-up and maintain misting output.
How to Use
Pairs Well With
Seedling trays, domes, and propagation essentials. High humidity during early stages dramatically improves clone and seedling success rates.
Environmental MonitorsA temperature and humidity monitor lets you track whether your AeroStream is actually hitting your target RH rather than guessing.

Frequently Asked Questions
Is the AeroStream suitable for a full-size grow tent?
No — not as a primary humidifier for a full-size tent. The 750ml tank and output rate are best suited to small tents, propagation domes, seedling areas, and spaces up to roughly 0.6x0.6m. For larger tents, a full-size humidifier with a larger reservoir and higher mist output is recommended.
Can I use tap water in the AeroStream?
Technically yes, but distilled or filtered water is strongly recommended. Tap water with high mineral content leaves white residue on leaves and internal components over time, reducing the unit's lifespan and potentially affecting plants.
Does it include a USB power adapter?
No. The AeroStream includes a USB cable but no wall adapter. Any standard USB-A power source will work — a phone charger, tent controller USB port, or powered USB hub.
Does it shut off automatically when the tank runs empty?
Yes. The AeroStream has an automatic shut-off that triggers when the water level drops too low, protecting the ultrasonic disc from running dry.
How often does the tank need refilling?
Run time depends on mist mode and output setting. On continuous mode, expect to refill every 4–8 hours. Intermittent mode will extend that significantly depending on the on/off cycle you set.
