Red Reishi Mushroom

Scientific Name: Ganoderma lucidum

Colonizes at 75-85°F (21-28 days). Optimal fruiting at 70-80°F, 85-90% humidity. Renowned medicinal mushroom, first fruits appear in 4-6 weeks.

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.

How are grains pepared?

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.

What type of mushroom bag do you use?

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.

Are spawn bags delivered fully colonized?

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.

How should grain spawn be stored during colonization?

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.
