Do you like mushrooms? Ever thought of growing your own ones? With the mushroom garden from Back to the roots it´s pretty easy.

Within ten days the grow-at-home mushroom kit lets you grow up to 1 1/2 lbs of oyster mushrooms per box. Believe it or not, but they grow on recycled coffee grounds.

Want to know who came up with this innovative idea?

As written on the homepage back to the Roots was founded by Alejandro Velez & Nikhil Arora during their last semester at UC Berkeley.

Two months away from graduation, and heading into the corporate world of investment banking & consulting, they came across the idea during a class lecture of being able to potentially grow gourmet mushrooms entirely on recycled coffee grounds.

Inspired by the idea of turning waste into wages & fresh, local food, they experimented in Alex’s fraternity kitchen, ultimately growing one test bucket of tasty oyster mushrooms on recycled coffee grounds. Soon they decided to forget the corporate route, and instead, become full-time urban mushroom farmers.
