Grow your own mushrooms with these sustainable kits (and a giveaway!)

Do it yourself mushroom kit

UPDATE: This giveaway has ended. Thank you to everyone who entered! Even if you didn’t win this one, you can still use coupon code mushrooms4me10 to save 10% when you buy a kit directly from Back To The Roots.

There are few things cooler than a science project you can eat.

Back To The Roots Ventures (abbreviated “BTTR Ventures,” which is then pronounced “Better Ventures”) was founded by a couple of smart guys who figured out how to take used coffee grounds (courtesy of Peet’s coffee) and use them as environmentally-friendly soil for growing gourmet oyster mushrooms.

Their sustainable startup is thriving, just like their mushrooms. This year alone, they’re on track to collect, divert, and reuse 1,000,000 pounds of coffee grounds on their urban mushroom farm in Oakland, CA, and in their home “DIY” mushroom kits.

Yup, that’s one million pounds of discarded coffee grounds that would have otherwise gone into landfills. How great is that?

Growing your own mushrooms with one of their kits couldn’t be much easier: First, tear open the side panel on the cardboard box. Next, cut two slits in the plastic bag. Finally, mist it with water twice a day with the included spray bottle. A fresh crop of oyster mushrooms will (miraculously) appear within just a few days!

Once you harvest your first batch of ‘shrooms, you can spin the recycled-cardboard box around and do it all over again — gracing your kitchen with up to a pound and a half of mushrooms from just one kit.

I have to admit, I’m geeking-out pretty hard for these kits. I ordered one for my nephews, and then connected with Nikhil, one of the company’s founders. After seeing just how excited I am about their product, he offered to send a free DIY Mushroom Kit — worth $20 each — to two lucky Eating Rules readers!

He’s also shared a 10% discount to anyone who wants to buy a kit directly from them; just use coupon code mushrooms4me10.

In order for an entry to be valid, the winner must be a fan of (“Like”) both the Eating Rules and Back To The Roots Facebook pages at the time of the drawing (sometime during the day of Tuesday, June 28th).
