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.

Usage advice
-
Demineralized water: limits limescale and extends the membrane's lifespan.
-
Positioning: place the mister below the terrarium level and aim the nozzle toward a ventilated area to promote air circulation.
-
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.
-
Humidity control: pair the HydroMist 4000 with an external hygrostat for even more precise automatic adjustment.
-
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.
