ent solution only, or in an inert medium such as perlite, gravel, mineral wool or coco- nut husk. “The nutrient water can be reused several times,” advises Hill.

education about building a sustainable water culture and infrastructure. Bullock’s mantra—“We harvest rain and greywater to create regenerative landscapes”—is a reflection of his enthusiasm for using water from sinks, showers and washing machines to irrigate plants as a way of increasing the produc- tivity of sustainable backyard ecosystems that produce food and clean water and shelter wildlife. “Greywater use makes people rethink the personal care
products, such as shampoos, conditioners and hair coloring, as well as cleaning products like clothes and dishwashing detergents, that go down the drain and into their irrigation system,” advises Bullock. He also promotes rainwater har- vesting to reduce the need and demand for water transport systems that threaten the health of the water cycle and local environments.
In order to build awareness for water recycling, Bullock emphasizes the story of how water comes to San Diego Coun-
ty, as well as a University of California-Los Angeles study that examined the potential of greywater to address California’s water challenges. “Study results showed that if just 10 percent of Southern Californians used their washing machine water for landscape irrigation, it would offset the need to build a large desalination plant. By turning wastewater into resourceful greywater irrigation, most San Diegans could cut their water bill by more than 50 percent and could recover the cost of a greywater system in one to two years,” he advises. A unified approach to farming and gardening that relates the ecology of the soil to that of the entire cosmos is the big biodynamic picture. To move humanity into a new paradigm as co-creators with nature, we must make every effort to nurture our connection to the land, become more mindful of better management and conservation practices and honor all natural elements as finite resources, not commodities. Ac- cording to Moora, as co-creators with nature, we also need to remember the spiritual aspect of stewardship. Perhaps gardeners, as they dig, plant, weed and harvest from the soil up, are fortunate stewards who are a little closer to sensing the energy forces of the cosmos that invite this connection.
