I just recently purchased one of these and the idea is purdy cool. I talked with the actual inventor of the system, and he said, its aeroponics ....but its really not. It actually drips nutrients from the top over the roots that are suspended in air , down to the reservoir. But he still says thats aeroponics.... because its supended in air not touching anything....doesnt matter if fine mist or drip. Reguardless of the bs , I still thought it was cool. What do you guys think? You can google tower garden for yourself or check out this link http://m.youtube.com/#/watch?v=qlDnbFFTpgI
