A Sewer-Pipe Worm Trough That Eats 100 lb of Pulp a Week
Vincent Mina, state president of Hawaii Farmers Union United, opened the symposium hall talks with the story of his 2,000-square-foot greens farm and the union's policy work, then walked through slides of his backyard worm system: half-pipe troughs cut from 2-foot sewer pipe and fed health-food-store juice pulp, mineral powder, biochar and Microbes (IMO-3). He also showed how he makes IMO-3 by the ton on wheat mill run and biochar, his compost screener, a hau-flower Food (FPJ), and a taro planting on old cane land mulched with sun hemp.
Found His farm makes a living on 2,000 sq ft, producing about 400 lb of greens a week
