Media: Rye Berries
Bag weight: 3 lbs
Inoculation ratio: 2.5-5cc (per 3 lb bag)

Our Reishi (Ganoderma lucidum) grain spawn features a unique strain renowned for its creation of striking, waxy, reddish-brown fruiting bodies, highly coveted for their valuable medicinal properties. Due to its bitter taste and resilient texture, culinary use is not recommended. Instead, it excels when dried for the creation of powders, teas, and stocks or can be skillfully extracted into a tincture.

Reishi mushrooms typically yield only one flush. When cultivating antler-shaped specimens, opt for spacious grow bags to accommodate the growth of tall antlers. For enhanced yields, encourage the development of conks rather than antlers by ensuring ample fresh air exchange in the cultivation environment.

Recommended Usage:

  • Reishi grain spawn is suitable for indoor production using a sterile substrate based on sawdust.

  • Please refrain from using grain spawn for log inoculation.

  • This product does not constitute a mushroom grow kit. Reishi grain spawn must be combined with a suitable substrate to trigger fruiting.


Upon receiving your spawn:
Upon receipt, promptly unpack it from the shipping box. Unfold the bag's top to allow for adequate airspace. Additionally, ensure that the filter patch remains unobstructed to facilitate proper airflow, essential for the thriving of these organisms.

  • Weight: Approximately 5 lbs

    Hydration: Average of 47%

    Bags: Gusseted 2.2 mil polypropylene

    Filter: High efficiency .2 micron

    Sterilization method: Commercial-grade autoclave sterilized

  • Temperature: 55-75°F | 13-24°C

    Humidity: Phase 1: Primordia (95-100%), Phase 2: Fruitbody (85-95%)

    CO2: Phase 1: Primordia( <1,000 ppm), Phase 2: Fruitbody (<1,000 ppm)

    Primordia - The earliest recognizable stage of fruitbody development. Also known as “baby mushrooms” or “mushroom pins.”

    Fruitbody - A fully grown mushroom, the reproductive structure of the organism in which the spores are produced.

    CO2 sensitivity - When CO2 levels are too high, yields will decrease, stems will become long and stringy, caps will be small, and/or growth will halt.

  • You can blend Reishi mushroom grain spawn into our substrate.

    Note: Before you can initiate fruiting, it's essential to combine grain spawn with a bulk substrate. If you're new to mushroom cultivation, we strongly advise considering the purchase of a book or guide on the subject.

  • You can distribute Reishi spawn within chopped straw or wood chips, Creating outdoor beds stands out as one of the simplest approaches for cultivating various Reishi mushroom varieties.

    Be sure to use clean, untreated products when making outdoor beds.
