Bulk Mushroom Substrate

About Our Magic Substrate

Our proprietary mushroom substrate blend, pre-mixed and ready to fruit right in the bag. Combine it with colonized grain spawn to fruit a wide range of gourmet and functional mushrooms.

What you are getting

Our proprietary substrate blend, pre-mixed and ready to use straight out of the bag. No fillers.

The substrate we grow on

This is the same blend we fruit our own mushrooms on in San Diego. Because we grow the fruiting bodies that go into our tinctures and dried products, this is a working farm recipe we rely on in small batches, not a formula bought off a shelf.

How to grow with it

Combine the substrate with fully colonized grain spawn, level and lightly firm the surface, then introduce fresh air and humidity to trigger fruiting. Keep everything clean to limit contamination, and harvest when the caps open.

New to growing? Our ready-to-fruit bags come fully colonized, no mixing required →

“We grow the actual fruiting bodies and lab-test every batch. That’s the whole product.”
