Yellow Reishi Liquid Culture Syringe (10cc)

About Yellow Reishi

Yellow Reishi (Ganoderma lucidum) is the classic Reishi species revered in Traditional Chinese Medicine, where it's known as Lingzhi — the “mushroom of immortality.” This strain produces golden-bronze conks with a lacquered, varnished appearance that make it one of the most recognizable functional mushrooms in the world. Our liquid culture offers a clean, vigorous isolate ready for hardwood substrate colonization and reliable fruiting.

Functional Benefits

Yellow Reishi is one of the most extensively studied functional mushrooms, with a long history of use for liver support, immune modulation, and general wellness. Its triterpenes (ganoderic acids) are associated with hepatoprotective effects, while its polysaccharides support balanced immune function. Traditionally prepared as a decoction or dual-extraction tincture, Reishi is valued for adaptogenic and calming properties that promote restful sleep and stress resilience.

Growing Notes

• Difficulty: Intermediate
• Preferred substrate: Hardwood sawdust blocks or hardwood logs (oak, beech, maple)
• Fruiting temperature: 70–85°F (21–29°C)
• Colonization speed: Moderate
• Special considerations: Reishi prefers warm, humid conditions and benefits from a casing layer or top-fruiting approach. Provide ample fresh air exchange for conk formation, or restrict airflow to produce antler-style fruiting bodies. Harvest before spore drop for the highest functional quality.

Usage Instructions

• Sanitize your work area, tools, and contact surfaces before handling.
• Prepare grain, substrate, agar, or grow kits according to your standard operating procedures.
• Introduce the liquid culture using sterile or near-sterile technique (e.g., in front of a flow hood or still-air box when applicable).
• Maintain species-appropriate incubation and fruiting conditions for temperature, humidity, and fresh air exchange.

Shelf Life & Storage

Store refrigerated at 34–39°F (1–4°C) away from direct sunlight. Under proper storage, typical shelf life is 3–6 months unopened. Always visually inspect for contamination, damage, or off-odors before use.

Quality & COA

Each batch is prepared using standardized procedures and test-inoculated on appropriate media before release. These internal checks act as our in-house Certificate of Analysis (COA) to confirm viability and cleanliness at the time of packaging.

How to Use This Liquid Culture

1. Sterilize the injection port on your grain bag with an alcohol prep pad.
2. Shake the syringe vigorously for 10-15 seconds to disperse the mycelium evenly.
3. Inject 1-2cc of liquid culture through the self-healing injection port of your grain bag. Less is more — 1cc is usually plenty.
4. Seal and incubate the bag at 70-75°F in a clean, dark space.
5. Wait for colonization — white mycelium will begin spreading through the grain within 2-4 weeks.

Temperature & Timeline: Colonization typically takes 2-4 weeks at 70-75°F. Warmer is not better — temperatures above 80°F increase contamination risk.

Signs of Success: You'll see white, fluffy mycelium spreading outward from injection points. The grain will become covered in a uniform white coating when fully colonized.

Next Steps: Once the grain is fully colonized, transfer it to a bulk substrate or introduce fruiting conditions, depending on your setup.

Common Mistake: Injecting too much liquid culture does not speed up colonization — it wastes culture and can introduce excess moisture that encourages contamination. Stick to 1-2cc per bag.
