EA Headquarters (EAH) Mini-Farm, Willits: Challenging soil with high levels of magnesium and nickel. Five-month growing season, usually with cool nights below 60°F, which slows down nutrient cycling, and often hot days in the 90° to 104° range, which also slows down nutrient cycling and pollination. Temperatures down to 24° in winter and as low as 18°. Rain 40-80 inches, usually the former; sometimes, though rarely, as much as 5 inches in one day.
