Prior to inoculation, our grains are sterilized using an autoclave. This a high-quality growing medium with minimal caramelization and Maillard reaction. Our lab and inoculation room are positive-pressurized cleanrooms, using a HEPA filtration system.

We inoculate our sterilized grain mix (organic sorghum, wheat and gypsum) with a G1 liquid culture. We do not expand beyond the G1 master bag. As a result, our stronger, healthier G1 spawn will;

  • colonize in your substrate quickly and,

  • consistently produce higher yields than any other commercially available spawn.


Choose from more than 20 strains and species or request your own custom blend.
