What You Get (Per 100 sq ft)

  • Custom Seed Mix of cowpeas, daikon radish, and winter rye — pre-treated with minerals and beneficial microbes for rapid germination and root development

  • Booster Blend of biochar, worm castings, and crushed minerals — designed to house and feed microbes through winter
