HydroMist 4000 – Ultrasonic misting device 4 L with extendable hose

The HydroMist 4000 is a compact ultrasonic humidifier designed to continuously and silently recreate the fog conditions your mushrooms, reptiles, amphibians, tropical plants, or seedlings need. Its 4-liter tank reduces refills, while its extendable hose directs the mist exactly where needed – from the horticultural greenhouse to the vertical terrarium.

Key points

• High-frequency ultrasonic atomization: micro-droplets < 5 µm that humidify without soaking the substrate.

• XL 4 L tank for 12 to 48 hours of continuous operation depending on the chosen flow rate.

• Adjustable flow rate (up to 300 ml/h) via front dial; adjust humidity in seconds. 

• Translucent extendable hose 40 – 160 cm (360° adjustable) + suction cups for targeted diffusion. 

• External probe (1.5m cable) to measure humidity inside your tent / aquarium.

Silent operation < 30 dB: does not frighten animals or disturb sleep. Safety automatic shut-off when water level is insufficient; prevents overheating. 

Technical characteristics

Usage tips

1. Demineralized water: limits limescale and extends the membrane's lifespan.

2. Positioning: place the mister below the terrarium level and aim the nozzle toward a ventilated area to promote air circulation.

3. Weekly cleaning: empty the tank, wipe with a soft cloth, then rinse with warm water. A monthly soak in diluted white vinegar (1:3) will remove mineral deposits.

4. Humidity control: pair the HydroMist 4000 with an external hygrostat for even more precise automatic adjustment.

5. Hose precaution: avoid pinching or bending the hose downward – condensation could block the mist flow.

With its long autonomy, adjustable hose, and overheat protection, the HydroMist 4000 is the simple and affordable solution to maintain a stable tropical climate in your growing spaces or animal habitats.
