Dutch Masters Humidifier DM-4007 – simple, reliable humidification for small rooms and grow tents
The Dutch Masters DM-4007 is an ultrasonic cold-mist humidifier that keeps the humidity in small rooms and grow tents at the right level. With a capacity of 260 ml/h, an 8-litre water tank and a 360° directional diffuser, it spreads the moisture evenly. You set the output with an analogue control knob: no menus, no fuss.
Main features
- Ultrasonic cold mist: no heating element, so no extra heat in your grow tent.
- Humidification output: up to 260 ml of water per hour, suitable for small growing areas.
- 8-litre water tank: long run time before you need to refill.
- 360° directional diffuser: point the mist exactly where you need it.
