Back to the Roots

Indoor Garden Kits

Home Grown

Want a fun, ready-to-grow way to connect with your food? Back to the Roots makes kits that are perfect for growing a bit of it right at home. No green thumb and no yard space needed. Each kit contains everything except water and sunlight.

Founders Nik and Alex are two UC Berkeley buddies who were inspired by the idea of growing
mushrooms in coffee grounds. Their business ethics professor mentioned it and Nik and Alex took it to heart. They launched their business while still in school, and since it has won all kinds of awards, including being named to BusinessWeek Top 25 Social Entrepreneurs.

Back to the Roots started their sustainable mushroom kits with discarded coffee grounds from Peet's Coffee. They expanded to more products, and the latest is Garden in a Can which lets you grow herbs. These kits, too, use recycled organic matter—biochar from Colorado, which is the charred remnants of organic agriculture waste. It’s great for indoor growing because it retains moisture, aerates soil, and increases nutrient absorption.

Back to the Roots kits are satisfying, sustainable ways to cultivate your own at home—indoors or out.

  • Jasmine

    Hi everyone! This is Jasmine Jackson, the Community Happynes Guru at Back to the Roots. Just over a year ago, our two founders, Alejandro and Nikhil graduated from UC Berkeley and during their last semester went from investment bankers to full-time urban mushroom farmers after becoming passionate about a newly learned fact: gourmet mushrooms can grow entirely on recycled coffee grounds! We're passionate about turning the whole idea of waste 'upside-down' through our easy and fun kits. I'm excited to answer any questions you may have about our kits or how we got started and hopefully have you growing your own 'shrooms with a brew soon! :)

    Love your story guys! I'm curious, do the coffee grounds lend themselves to the growth of a particular mushroom or did you choose which mushroom you were going to grow? If it was a choice, why did you choose this variety over a different variety?

  • Nik
    2/18/2011 2:03 PM

    @Kate: Hey Kate! There are actually only a few mushrooms that grow well on 100% recycled coffee grounds, and out of those, oyster mushrooms have the best yield and fastest growth cycle. Also, if you look at oyster mushrooms in stores, they're often really beat-up looking because of how delicate they are, so we thought it had all the qualities to make a great kit! They grow the fastest, offer the most yield, and are delicious gourmet mushrooms, but hard to find fresh! Thanks for your interest in the kits!

    what a cool post... I'm growing mine right now & just plucked my first havest -- bought at my local WF two weeks ago!

    How long do these mushrooms continue to grow and how many pounds (on average) is harvested from one kit?

  • Nik
    2/18/2011 2:14 PM

    @Liz: Hi Liz! You can get at least 2 harvests from the kit (though we've had some customers get more!). The first harvest will be around 1lb, and the second, as nutrients are used up, is often around .5-.75 lbs. Hope this helps!

  • Mary
    2/18/2011 5:15 PM

    @Nik Arora: 2 pounds of mushrooms for $40? You have to be kidding. What's up with that? Am I missing something?

  • Julia
    Julia – Grommet Team
    2/18/2011 6:11 PM

    @Mary: Hi, Mary! There are two kits included in today's Grommet. So that's about 4 pounds of mushrooms - and, based on our experience, probably more. Some people get 3-4 crops out of each kit. You'll definitely get two crops out of each one. The best part about growing these yourself is that they mushrooms are very fresh. Mushrooms don't tend to store or travel very well. The ones I can buy in the grocery stores here in Boston come all the way from Oregon and don't look great when they get here. Personally, I love having access to fresh mushrooms that have just been harvested and thrown into my pots and pans. And being able to grow them myself is a priceless experience for any kid at heart!

    Have you tried grown MORELS, would be very interested in the process, please advise. Thank you MickeyZ

  • Nik
    2/18/2011 5:57 PM

    @Michelle Zastawny: Hi Michelle! We have not tried to grow Morels (they don't grow well on coffee grounds), so unfortunately, I can't offer too much help here. However, if you look a book by Paul Stamets: Growing Gourmet and Medicinal Mushrooms, it may have more information there. If you haven't tried oyster mushrooms though before, I'd highly recommend them. They have a chewy, almost meaty texture, with a woody flavor that makes them great in soups, pastas, sautes, or even just grilled!

  • Christy
    2/18/2011 3:25 PM

    Just a quick question about the containers. Do you use recycled materials for the bags and box and are they recyclable?

  • Nik
    2/18/2011 5:55 PM

    @Christy : Hi Christy! The container is made out of post-consumer recycled cardboard and printed on with soy ink. The bags are recyclable, though because of the special conditions we need for mushroom growing, are not made out of recycled material. We're always working to improve our zero-footprint mission though and open to suggestions / feedback! Thanks!

  • Laura
    2/18/2011 4:27 PM

    Luv this concept ... can't wait to try! Quick Question, have you tried growing Shitake mushrooms this way??

  • Nik
    2/18/2011 5:41 PM

    @Laura: We have tried shiitakes (and still working on them!) They have a much longer life-cycle to grow, months rather than days, and offer less yield on the coffee grounds. We're still working on it though, and hopefully will have something out by the holidays this year. Stay on the lookout in a few months though for a few new types of kit we'll be launching to compliment the Mushroom Garden - rosemary, thyme, and basil kits!

    My daughter tried one of these about 5 years ago (don't know if it was yours or not), but it was a total bomb. She got a tiny part of one mushroom. )<:

    Hope yours have better results. Libby

    2/18/2011 5:23 PM

    @Libby: Hey Libby! Thanks for the comment. It definitely could not have been ours, as we just launched our kit last March! However, our number one priority, by far, is making sure all our customers are 100% satisfied with their experience, and we promise to take care of you! We guarantee all our products, and will offer you a replacement if your daughter isn't satisfied. Thanks for the interest and let me know if you have any more questions!

    I bought two kits, the first one has yet to grow a single mushroom - the other kit has some sort of green scary looking liquid in the plastic and I'm afraid to even open it. I am in the process of contacting the company to return these and hopefully get a refund. I don't want to say this idea is bad or doesn't work but my first attempt is still sitting there w/ nothing growing and I'm not about to open the second kit w/ the green slimy stuff inside. I hope the company will get back to me on how to return these.

    I've had my kit for a month...followed the instructions...and nothing is growing at all. I tried contacting the company through their web site and have received no response at all, it has been more than a week.

    It's a great idea but I am disappointed with both the product & the company!

    My kit looks to be growing mold on the top (Black part in the bag where the grounds are exposed) and I have yet to see any mushrooms start on the white part (mycelium) but its only the 4Th day... Just worry the mold on top will take over.

    any advice on what to do?

Sounds like you got a really healthy bag with all the white mycelium (roots) should start seeing mushrooms pop out really soon! Did you soak the bag in water overnight? Also, if you send me an email to Nikhil at with a picture of your the bag inside, I'll be able to get back to you asap with some more detailed tips & tricks to get the best mushrooms!

    I ordered a kit for myself and a good friend. After two weeks of faithfully misting, I never got sprouts, just moldy looking stuff. My friend started to see sprouts, then they just kind of disappeared. We followed the directions perfectly - any idea why this would happen to both of us? Thanks.

    I ordered this kit and my mushrooms looked nothing like those in the picture. They looked more like crystals and were moldy, so I was afraid to eat them. Can send you a pic if you want but I was very disappointed since I followed the instructions to the letter.

    I had the same experience as some of the others, in which I did everything I was supposed to do and got nothing. Then, after a few weeks of forgetting about it (figuring it was a dud), suddenly I noticed I have a whole bunch of mushrooms! So, for those of you worried that you haven't gotten anything yet, be patient... they still may come.

    I'm so disappointed in this product. I gave it to my father for Father's Day, and was so excited about it, telling people that I had found the perfect gift for my dad. He began gardening after he retired, and discovered that he had a green thumb, doing very well with his vegetable garden. This has been his passion every year since retirement. The past couple of years have been more difficult for him due to age and related issues, and he had to rely more on others for help. A few months ago he finally admitted that this was just too much for him and gave up his garden (his space in the condo development garden was given to someone else), and I heard the disappointment in his voice. When I found these mushrooms I thought it was perfect for him, as a way to continue his gardening!! My folks told me that they followed the directions exactly, holding their breath, waiting...waiting, but nothing ever grew! I know they were disappointed but I felt worse, because I gave this to them.

    Any thoughts???

    @ Janet K: Lucky father to have you looking out for creative ways for him to enjoy his green thumb. Here's some tips to get the stubborn mushrooms growing: (1) Make sure the kits are not in and or around heating systems while in use, (2) soak the bag in water for 24 hours to ensure proper hydration and (3) make sure the incision was made in the bag and the soil.

    If the mushroom remains "dormant", please let our Customer Support Team know at [email protected] & we'll help you resolve the issue.

    @ Margie and @ Lori,

    Thanks so much for reaching out! We don't recommend using your own coffee grounds because there is a risk of cultivating mold when you use your own coffee grounds. While the mold isn't dangerous, it can prevent your mushrooms from growing. However, lots of our customers experiment with their kits and some have even been successful using their own coffee grounds.

    @ Heather G We have been helping Back to the Roots since last year and they have indeed gained much more visibility in the last year, but their distribution is not national. You are lucky to live close to a local place, like Home Depot, taking a chance on this Grommet. I encourage you to support them wherever you encounter this, or any, Grommet.

  • Merle

    Do the mushrooms start growing right away on their own or do I need to do something to get the process started (meaning I could get them started a while from now)? I'm trying to figure out whether I can buy these now for Christmas or should I wait until the time gets closer.

    @Merle Firstly, thanks so much for considering our kits! They make great gifts and are dormant until the new mushroom farmer provides the mushroom garden with it's "first rain" (a 12-24 hour soak). This mushroom garden make a unique gift of growing and can be stored in a cool dark area for months at a time! Cheers!

    @ Jasmine Jackson - I purchased this kit recently and followed the instructions. It's been around 3 weeks since I did the soaking and have been misting every day, however, I have seen no signs of any mushrooms growing. Is there something else I can do, please advise.

    Please disregard my last message, my mushrooms started growing 2 days ago and it is so exciting to watch how quickly they are growing now. Every time I walk by them, it seems as though they have grown more. It's fun and I can't wait to harvest them.

The launch day conversation has ended. Please direct further questions about this Grommet to our Community Experience Team.
