Reishi Mushroom SpawnNorth Spore
*PLEASE READ NOTE ON SPECIES VARIANTS BELOW!*
Ganoderma lucidum / tsugae: Beautiful, waxy, reddish-brown shelf-like fruit bodies are a highly prized immune-boosting medicinal used to treat a long list of ailments.
Reishi spawn comes in three distinct styles:
Grain Spawn (Ganoderma lucidum only)- Indoor only! The indoor method of growing reishi takes basic laboratory/clean space infrastructure, though they are a great mushroom for indoor commercial cultivation for beginning growers. They do not require humidified fruiting rooms as they can grow entirely inside their bag.
Plug Spawn - Great for first time mushroom log growers. Used for small projects. 1-10 logs.
Sawdust Spawn - Used for larger mushroom log projects, or by those wanting to inoculate logs every year. Used for small to large enthusiast or commercial projects. Best for inoculating 10 or more logs. *You need an Inoculation Tool to use Sawdust Spawn! For larger projects you may want to purchase an Angle Grinder Adapter and specialized 12mm drill bit!
On Logs - Reishi likes any of the three log methods and colonizes in 12-24 months. It prefers oak and fruits in the summer. After a 1-year colonization period above ground, Reishi logs may be buried under 2 inches of top soil to mimic its natural method of production. Mushrooms will fruit from the logs and emerge from the soil.
*NOTE: There are two species of reishi available. All plug spawn is Ganoderma lucidum, which grows on hardwoods. This species of Reishi grows only on hardwoods and is genetically different from the species that grows on hemlock trees. Ganoderma lucidum Reishi will not work in hemlock wood!
If you wish to inoculate hemlock wood, you must select Ganoderma tsugae Sawdust Spawn. Ganoderma tsugae Reishi will not grow on hardwoods!
Check out our Spawn FAQ to figure out what type of logs you can use!
Indoor Commercial Production - Use Grain spawn for indoor cultivation. nameko mushroom grain spawn can be mixed into sterilized hardwood sawdust to create reishi substrate blocks. This process requires a fair amount of infrastructure. We recommend purchasing a book on mushroom cultivation if you are interested in pursuing this style of mushroom production as a hobby or profession. We recommend 'Radical Mycology: A Treatise on Seeing and Working with Fungi' by Peter McCoy, 'Organic Mushroom Farming and Mycoremediation' by Tradd Cotter, or 'Growing Gourmet and Medicinal Mushrooms' by Paul Stamets.

Difficulty: Advanced (outdoors) / Beginner (indoors)
Outdoors, Reishi mushrooms are great for enthusiast growers who have had some success with other species. Reishi works best when fully colonized logs are buried underground. This is a species that is cultivated on logs commercially in Asia. Most commercial producers in North America grow Reishi indoors. Growing reishi indoors is great for beginner indoor mushroom growing operations, though indoor cultivation requires much more infrastructure and specialized knowledge.
Cooking: Not for culinary use but recommended for teas and tinctures. To make a tea, break Reishi into pieces and simmer in water for two hours.
Properties: Known commonly as the 'Mushroom of Immortality' in Chinese, Reishi is a highly esteemed medicinal mushroom thought to promote longevity and overall health. Studied most for its ability to boost the immune system, Reishi extracts stimulate T-cell action, Natural Killer cell activity, and Dendritic cell maturation (Gao, 2004). Other pharmacological effects of Reishi extract include the following: anti-inflammatory, antibacterial, antiviral, reduces blood pressure, lowers cholesterol levels, promotes anti-tumor activity, and acts as a central depressant to relax muscles (Hobbs, 1995; Gao et al., 20014).
