They start by growing soil through composting to replace the existing contaminated urban soils and continue with growing worms, mushrooms, sprouts, which alone provide from $5 to $50 worth of production per square foot, and fish in integrated urban agricultural systems. There are seven different levels of production in their greenhouses, some of which are heated by compost. At their main farm, a quarter of their electricity comes from solar electric panels and 70% of their hot water is solar heated. They also have an anaerobic digester for methane production and electricity.
Growing Power also provides hand's on education and summer jobs for children planting flowers by sidewalks and corners, a measure which actually reduces crime. Green Power also has community kitchens for food preservation and processing. They are now building a five story vertical farm at their national headquarters and planning for 15 regional centers.
