Ultrasonic foggers are kinda cool- I've played with a few in an aerocloner and an aeroponic watering system for flowering plants a few years back. Unfortunately, they don't live long in nute solutions. The vibration of the piezoelectric diaphragm seems to cause nutrients to come out of solution and crystallise on the diaphragm after a few weeks use. This increases the mass of the diaphragm and eventually causes it to stop vibrating, halting mist production.
Smart people do, anyway. You can always tell the noob in the crowd- forever trying questionable and experimental things in a grow and later complaining that they've got no buds to smoke... shock, horror, surprise!
This much I'll tell ya- when the 'next big thing' in dope growing comes around, it won't be noobs discovering it. It'll be the well experienced growers who can sort the wheat from the chaff.
There's a very good reason why you see the big producing growers on here using the methods they do- it's because they work!
