• Inside the Grow Tent: Place the humidifier directly inside the grow tent to maximize plant growth potential by precisely controlling humidity within the enclosed space.
• Outside the Grow Tent: Use the provided flexible hoses to deliver mist into the grow tent from outside. This saves space inside the tent while still achieving optimal humidity.

4.3 Filling the Water Tank

The humidifier features an effortless top-fill design:

1. Remove the top cover of the humidifier.
2. Pour clean water directly into the 6-liter tank.
3. Ensure the water level does not exceed the 'MAX' line.
4. Replace the top cover securely.

The black opaque tank design helps prevent algae buildup by blocking light, ensuring clean moisture.

4.4 Connecting the MH-Sensor

Connect the 3m MH-Sensor to the designated port on the humidifier. This sensor monitors temperature and humidity in real-time, allowing for accurate climate adjustments.
