An ultrasonic mist maker seems a superior solution for an aeroponic crop, since there would less problem with clogging, power consumption, noise, etc.
However, current ultrasonic mist maker make really small droplets of size less than 10 microns. It seems 50 microns is the sweet spot needed for long term growth of plants. I have two questions: 1) Is it theoretically possible to create droplet of size 50 microns using ultrasonic technology? 2) If the answer to the above is yes, do you know of a commercial product or even something that can be bought out there and assembeled which can create 50 micron droplets
