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.
Grow Guide
Ganoderma Lingzhi
Antler reishi forms long antler like growth when light stays low and CO2 stays high.
Ganoderma lingzhi is the most widely cultivated and commonly used reishi species in commercial products. It is native to Asia.
Expect a tough fruiting body with a bitter profile. People usually brew it as tea or process it into extracts rather than cook it as a standard edible mushroom.

Compounds Identified in Ganoderma Lingzhi
Every strain carries its own chemical signature. These are the compounds found in this species — documented in the scientific literature for anyone who wants to dig deeper.
4 Active Compounds
-
Ganoderic acids and Ganoderma triterpenoids
Known Benefits
- Hallmark Reishi compounds. Reviews consistently describe anti inflammatory and immunomodulatory activity in preclinical studies, including effects on inflammatory mediator signaling.
-
Beta glucans and polysaccharides
Known Benefits
- Immune modulation via pattern recognition receptors including Dectin-1. Supports innate immune signaling and downstream adaptive responses. Often studied for immune resilience and inflammation balancing.
-
Ergosterol
Known Benefits
- Provitamin D2 precursor in mushrooms. Converts to vitamin D2 with UV exposure. Also reported antioxidant and anti inflammatory activities in reviews.
-
Phenolics and polyphenols
Known Benefits
- Antioxidant and anti inflammatory actions. Often linked to improved oxidative stress markers and to gut microbiome interactions that may influence metabolic and cardiovascular health.
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.
