Check out a video below: Back to the Roots was founded in 2009 by Alex Velez and Nikhil Arora, and their intent is to create sustainable grow-at-home products, like their mushroom garden. So far, their mushroom garden has "diverted and transformed over 50,000 lbs of coffee grounds into a rich soil for gourmet mushrooms, sustained 10 urban school and community gardens by donating BTTRs premium soil amendment, and grown 7,500lbs of delicious gourmet mushrooms sold at all Nor Cal Whole Foods Markets."
The mushroom garden sells for $19.95! Buy it for yourself or as a gift! Read more about them in this article from The New York Times Bay Area section.
