The patented Dewey Mister is an extremely effective and efficient air-powered aeroponic mister. When submerged in water, the air pressure pulls and water from the reservoir and builds up pressure as it mixes. When excess pressure is achieved, the water mixtures then explodes out of the top of the mixer, creating an irrigation mist for your plants. The Dewey Mister continuously mixes and sprays the cool nutrient water. The mister almost never clogs and is therefore great for any nutrient solution, including organic blends. This eliminates the need for a water pump and an air-stone. You’ll be amazed at the simplicity and effectiveness of this awesome and innovative mister!
