Meet The Experts

Why This Course?

Unlike with online forums like Reddit, with our course, you get access to leading mycology teachers who will support you every step of the way.

  • Three expert mycologists available online Tuesday-Friday and Sunday
  • Share pictures of your grow
  • Get your questions answered

From prep to harvest, the whole process takes about nine weeks.

  • Most of this time is spent waiting—patience is key!
  • Only a couple of fuller days needed for inoculation and transferring the substrate
  • Once they’ve begun growing, you’ll check to mist and fan periodically

Once you have the setup, you can use it forever, to grow an infinite supply of mushrooms for your friends and family. All the supplies cost less than $100.

  • You’ll get about 30 to 60 dried grams of mushrooms from a spore syringe, which costs about $10
  • Go as fancy or as basic with your setup as you’d like
  • All supplies can be found online and in local hardware/garden stores

You don’t need extra space—in fact, a space the size of a litter box should be enough room.

  • You’ll need a small, dark space for inoculation
  • For colonization, you’ll need a space with indirect light
  • 75-82F is ideal, but you can always get creative to regulate temperature

You’ll get access to an invite-only, private DoubleBlind community to bond with and receive support from your fellow growers.

  • The DoubleBlind community is very global—connect with growers around the world
  • Get grow tips and recommendations

Kathy, DB 101 Student

Glory Hallelujah I saw that DoubleBlind was offering a class on how to grow mushrooms!

“The entire journey from supplies to harvest was really magical for me. The 9 week class provided step by step instructions by using a written guide and videos which were excellent. I know this sounds like this is too good to be true but it was true and it was amazing how much effort went into this class and how much attention we received. We had a team of highly qualified mycologists.”

Fred, DB 101 Student

Thanks to our amazing teachers and our incredible community now I can cultivate my own mushrooms.

“I was already curious about mycology, but DoubleBlind’s How to Grow Mushrooms course came right on time in quarantine. I loved that I could get access to expert knowledge throughout the grow process.”

From Our Founders

“It’s been so humbling and beautiful to watch our mushroom community grow to thousands of people from around the world, who are supporting each other on their mushroom growing journeys. Some of our students have even gone onto become TAs for the other students, and many have graduated saying the course changed their lives and the relationship they have with their medicine and food. This course is really just a part of a movement to take our health back into our own hands, and we’re grateful to be a part of it at DoubleBlind.”

We’ve bought almost everything but the terrarium/tub, and we’re excited to get started! Between the videos and the FAQ docs, I feel really well prepared to jump into this. Can’t wait!

How to grow mushrooms 101 is a very easy to follow course. All of the steps are explained very well. With silly humor added in. The course explained the extreme need for sterile equipment. And also gave me a list of everything I need to purchase. I will be able to grow with confidence and will be able to provide myself with my own supply of the sacred medicine. How to grow 102 offers several more advanced options for growing your own mushrooms. They are also explain very well. But for now I think I will start with the basic outline. Thank you for giving me a way to provide my own source of this valuable medicine.

Thank you!! I feel so much more confident in this. The internet scared me - there were way too many methodologies, and it sounded like such a hard core process. This made everything fun and easy.

First, the videos were so much fun to watch while conveying great educational content. I am on my first experiment with growing, and so far I have had success beyond my expectations: 7 out of 10 bags inoculated produced uncontaminated mycelium cakes, and I just started the fruiting chambers. All the instructions are clear and easy to follow.

Fun and entertaining class. It's short and gives you a walk-through of what's ahead. It lacks some depth and details and I would supplement it with books and other trusted resources.

Some important information left out of the course materials that would be easy & helpful to include - like use a SAB for lower contamination.

Thank you for organizing the course in a way that helps learners to easily understand how to grow! My only concern is that the discord forum could be a little more attended to - I have yet to receive a response for a question I asked almost two weeks ago. Sometimes, Reddit forums can be a better place for these questions.
