Our project creates a living indoor commercial growing system to feed urbanites, replacing vast amounts of the land, water, fuel, and waste found in traditional farming and food transport systems. The current system for growing food in North America uses vast amounts of land, creates tons of waste, and burns millions of barrels of fossil fuels transporting food from farms to supermarkets. Traditional farming uses millions of gallons of water, an increasingly precious resource. Also, this system is vulnerable to weather that cannot be controlled but has the power to destroy a season of crops in a short period. Our solution is to move some crops much closer to the source of consumption, using far less space to do so, by creating an indoor hydroponic vertical growing system that is not dependent on soil or sunlight, is not subjected to weather changes, and requires little or no transport. Because our system keeps the crops alive until they are consumed, there is little waste because, for example, a head of lettuce that’s not eaten today simply grows for another day, staying fresh rather than spoiling. We can grow eight or more heads of lettuce per square foot of horizontal space using highly concentrated, energy-efficient LED lights to deliver the exact spectrum of lights required for green leafy vegetables, and not wasting energy by producing other unused kinds of light. Also, our system also uses just 10% as much water as traditional growing methods.
