the major problem i forsee with that model is that there is not much room for root growth also unless you trim the root bases periodically they will clog up the jets(misters)
it cand only take 3/5 Hours to kill a plant
take a look at this system go to
http://www.grow.com.au/ then look at airmonsta 5 aeroponics system the contanier used provides adequate room for the root system
i use a similar system i made myself
cost $50AUS do a bit of reaserch it can save you $$$$$
