Adjustable Cool-Mist Humidity Control for Indoor Growing

The RAM Ultrasonic Humidifier is designed to increase and maintain moisture levels in indoor growing environments. Its ultrasonic system produces a fine cool mist, helping to counteract the dry conditions that can be created by extraction fans, grow lights and other climate-control equipment.

Available with either a compact 5-litre tank or a higher-capacity 13-litre tank, the humidifier provides adjustable analogue output for straightforward control. The 5L model delivers up to 400 mL of mist per hour, while the more powerful 13L model delivers up to 1,100 mL per hour.

Important Information

This humidifier adds moisture but does not measure relative humidity. Use a separate hygrometer or compatible humidity controller where automatic environmental control is required.

Do not restrict or cover the mist outlet. Keep the unit and its mist away from grow lights, electrical connections and other equipment that must remain dry. Clean the tank and ultrasonic components regularly in accordance with the manufacturer’s instructions to limit mineral deposits and maintain consistent output.
