This powerful and compact humdifier produces water vapour via ultrasonic vibration for a very fine micron size droplet correcting the humidity of the air dried out by central heating or environmental conditions associated with indoor growing. Each unit is cool running and gives 100% humidity. Mist Makers maintain the optimum growing environment required for cuttings and seedlings as well as with growth through the vegetative stage of your plant cycle. Place in a large propagator or centre of the growroom and watch the vapour float around your cuttings producing rapid growth rates and delivering greater nutrient uptake as well as nutrient transportation. Your plant's roots will grow to love the Mist Maker! The Mist Maker is cool running (most humidifiers on the market have a heat element). It features a very quiet operation and requires no wiring as it plugs directly into a standard electrical plug socket. This product uses a special coated disc for less frequent changing and works in an instant and can last up to 2000 working hours. It has an output of 240ml per hour.
