im sorry i missed the question. and if ur asking that a humidifier will work as aeroponics then i would say no. never used aeroponics but figuring how one works and how the other does. iwould say no. a humidifier gets hot and steams aeroponics is a method of fogging the air with wtv u would use, pumps and water heads that make the solution very very fine. besides i dont think the price would be much different. u can pick up a pump cheap and everything else is cheap aswell. for a small grow.
