The Back to the Roots' grow-at-home mushroom kit lets you grow up to 1 1/2 lbs of gourmet, tasty oyster mushrooms per box.... harvest your first crop in as little as 10 days!  Inspired by the idea of producing local, fresh food from what was an urban waste stream, Back to the Roots has created the Grow-Your-Own Mushroom Garden which lets anyone, across the country, grow their own gourmet mushrooms at home!  This kit uses recycled coffee grounds as a base for the growing of pearl oyster mushrooms.
