as wolfcott said dont waste your money on aerogardens !i bought one only because i couldnt get the ph rite in the soil i was using. its such a waste i bought mine for $250 AUS dollars and i could of just made my own DWC for $40and a dwc is 10x better ! but if u end up buying one regardless u will need more lights if u want a decent yield , and i wouldnt plant more then 2 plants per aerogarden
