Reishi, revered in traditional medicine as the “mushroom of immortality,” forms striking reddish-brown, lacquered fruiting bodies with a woody texture. It’s not eaten for flavor but extracted for its triterpenes and beta-glucans, valued for immune support and adaptogenic properties.

About Our Grain Spawn: Built on the same Unicorn 4T-INJ bag platform as our sterilized grain, this spawn is inoculated to order with low-passage, agar-verified culture for clean, vigorous growth. Because it’s freshly inoculated, the bag will arrive partially colonized—or colonization may become visible within a few days, depending on species and shipping conditions. Hydration and gas exchange are tuned for fast, even colonization.

Frequently Asked Questions

While other methods may work, we prioritize quality and consistency. We utilize a thorough clean, soak, heat, and strain method that fully prepares the grain before sterilization. This additional effort results in a more consistent, high-quality grain that optimizes mycelium colonization and ensures stronger, healthier growth.
We only use the industry standard Unicorn Bags. 3 pound bags use 4T-INJ Bags and the 5 pound bags use a 3T. Both Include a 0.2-micron filter patch for controlled airflow and a secure injection port, facilitating easy inoculation with liquid cultures or spore syringes.
Colonization rates upon receipt will vary based on variety, transit time and temperature. Grains are Inoculated to order, so in most cases you will see visible mycelial growth upon receipt, but it's possible this will not occur until a couple days after. This depends on species and temperatures the grain spawn is exposed to during transit.
Keep in a cool, dark place during and after colonization. Once the bag reaches ~25% colonization, perform a gentle break and shake to redistribute mycelium and speed completion. Avoid opening until fully colonized and ready to expand into your substrate.
