Goldman Sachs and Prudential are investing in vertical urban gardening.  Entrepreneurs envision selling fresh produce to high end restaurants and discounting to low income neighbors.  Land costs high, but some in the sky.  Entpreneurial opportunities abound.

Efforts to grow green business in New Jersey’s largest city Newark were bolstered by the announcement of a $30 million public-private commitment to create the world’s largest indoor aeroponic garden in Newark’s Ironbound, a community in serious need of investment, good jobs, and fresh produce.

Essentially, aeroponics is a plant-cultivation technique that doesn’t require soil or sun: Roots are exposed to the air and nutrition delivered via a fine mist.
