Growing mushrooms is a simple—yet radical—response to our times. In the world of big pharma and the rise of corporadelics, it’s empowering to control where your food and medicine come from. And when you grow your own mushrooms, you’re not just cultivating the fungi... You’re cultivating a space for your mental, spiritual, and physical wellness to thrive by connecting deeper with what you put into your body.

Are you ready to empower yourself? Whether it’s your first time or you’ve tried your hand at growing before, our DoubleBlind’s 101 and 102 How to Grow Mushrooms courses (available separately or bundled together) will teach you the foundations of cultivation and provide you with a deeper understanding of how mycelium grow, and why experienced growers choose varying teks.

The movement is here. DB has taught thousands of people how to successfully grow mushrooms right at home. With their course, you’ll get video lessons and written guides, support from a team of expert mycologists, plus access to an invite-only community to connect with other growers.

Why Grow Your Own?

It’s cheaper! For $15-$20 worth of spores (not including cultivation supples), you can grow more than 100x more fungi than what you’d buy for the same price.

Peace of mind! DIY cultivation eliminates having to buy mushrooms from a dealer. You’ll know exactly what you’re getting, without having to wonder if they’ve been prepared poorly or are too old to be potent.

Deepen your connection to nature! Growing your own mushrooms—as food or as medicine—can deepen your relationship to them, while encouraging self-sufficiency and a connection to process, tradition, and community. Not to mention, growing your own can be empowering.

Let’s be honest—the reasons are endless. That’s why DoubleBlind is empowering fungi fans around the world to grow their on with their How to Grow Mushrooms courses. With the course, you’ll get 7 easy-to-digest video lessons and written guides, plus access to a team of mycologists who will help answer your questions throughout the process.
