Disclosed is a fully-automated greenhouse that utilizes hydroponic growing techniques in order to maximize the amount of crop production possible in a given footprint, and eliminates the need for soil, fossil fuels, pesticides and toxic chemicals. The greenhouse produces its own pure, clean water supply with proprietary, on-board atmospheric water generators incorporating water treatment technology, namely ozone, hydrodynamic cavitation, acoustical cavitation, and electrochemical oxidation to oxidize and destroy contaminants to maintain purity.
