Hericium Plugs: Lion’s mane is the common name given to a group of mushrooms of the genus Hericium. Lion’s mane mushrooms have a coral-like shape, with spindly branches that shoot out from the stem. They are white, pinkish or creamy yellow in color, and are noted for their fresh crab-like flavor and texture when cooked.
This mushroom will grow on a wide range of hardwood logs or stumps, including oak, maple, walnut, beech, chestnut and elm.

Oyster Mushroom Plugs: Oyster Mushrooms Reported Health Benefits: The Oyster mushroom has a firm texture when cooked and a "meaty" or oyster-like flavor which will add both texture and zest to most sauces or dishes.Oyster mushrooms are best known medically for their cardiovascular and cholesterol-controlling benefits. Oyster mushrooms contain mevinolin and related compounds which are potent competitive inhibitors of HMG CoA reductase (3-hydroxy-3-methyl-glutaryl coenzyme A reductuctase), the major rate limiting enzyme in cholesterol biosynthesis. In addition, they have been shown to have activity in the following: These mushrooms prefer tulip poplar, aspen, cottonwood, beech, willow, maple, oak, and sweet gum.

Maitake Plugs: Maitake Mushroom (Grifola frondosa) Hen of the Woods may best be known for its cancer-fighting properties. It contains grifolan, an important beta-glucan polysaccharide (molecule composed of many sugar molecules linked together). Grifolan has been shown to activate macrophages, a type of cell consider the " heavy artillery": of the immune system, explains Larry A. Walker, Ph.D., R.D., author of "Natural products update," published in Drug Topics, June 1997. D-fraction, one of the polysaccharides in Maitake mushroom, also energized the cellular immune system.
Will grow on a wide range of hardwood logs & stumps and some conifers: oak, elm, maple, sycamore, beech, plum, peach, hemlock, and many others. Logs may be laid on their side & partially buried.

Reishi Plugs: The Reishi mushroom can increase the production of interleukin1 and 2, resulting in inhibition of tumor growth. Studies show that Reishi can have a number of other positive effects on the body such as analgesic, anti-inflammatory, antioxidant, anti-viral (through its interferon production), lowers blood pressure. It also acts as a cardio tonic by lowering serum and increasing the production of interleukin 1 and 2, which results in inhibition of tumor cholesterol, expectorant, anti-tissue, liver protecting and detoxifying, protection against ionizing radiation, antibacterial, and anti-HIV activity. Will grow on a wide range of hardwood logs & stumps and some conifers: oak, elm, maple, sycamore, beech, plum, peach, hemlock, and many others. Logs may be laid on their side & partially buried.

Mushroom Plug Inoculation
Return to Top
All of these Mushroom Plug stains are bred to grow and produce mushrooms in a wide range of temperatures. They grow and produce mushrooms well in warm as well as cold climates.
Log cultivation is usually done with logs 4 - 6 inches in diameter with a length of 3 to 4 feet. Oak is particularly good for the cultivation of most mushrooms though many other species work well also: poplar, aspen, sugar maple, willow, alder and birch, among others.
The best times for cutting the logs are either in the winter months for spring inoculation or after July 15 for mid-summer or fall inoculation. When inoculating logs in the summer, it is best to do the inoculation in the morning in a shady place. When selecting logs for mushroom cultivation, choose healthy, living trees without signs of decay or mushrooms growing on it; if the tree is dead, it will certainly already have other, competingfungi growing in the wood. Sapwood and cambium are sources of nutrition for mushrooms
If you cut logs during summer, it is best to inoculate them within 3 weeks after they have been cut so that the logs will still have an adequate moisture content. After inoculation, the logs are just placed in a shady place out of the wind. After inoculation, the logs are just placed in a shady place out of the wind. The logs must be maintained in an environment above 40 percent moisture and kept fully shaded in the summer. Under natural conditions, mushrooms fruit in the spring and fall when temperatures are cool. Logs generally begin producing 6 months to 1 year after inoculation; after which, they usually continue to fruit for up to 4 years producing 1-2 lbs. per year.
Step 1
Drill 1 ¼ in. deep holes into the log spacing the holes about 6 - 8 in. apart within a row. Leave approximately 2 to 4 in. between the rows and offset the holes so that they form a hexagonal pattern. A 4 in. diameter log will need 6 rows; a 5 in. diameter log will need 7, and a 6 in. diameter log will need 9 rows. A 4 in. log usually is given about 40 - 50 plugs. The more plugs you use per log, the faster the wood will be colonized with mushroom mycelium.A large stump usually requires 100 holes arranged in a similar hexagonal fashion around the trunk and with holes on the top of the stump as well. All mushrooms are inoculated into logs in the same way.
Step 2
Hammer/Tap the plugs into the holes.
Step 3
Cover the plugs with the cheese wax. To do this, melt the wax in a pan which can be maintained at 300o F. An electric frying pan with a thermostat control works well for this.
If inoculating away from electricity, using a camp stove, make sure that the wax is hot when you apply it; otherwise, the wax will not create a tight seal and can easily fall off. The wax can be applied with a foam paint brush or cotton dauber.
Mushrooms can also easily be grown on a small scale for home consumption in a highly productive backyard mushroom garden with just a few logs.
By inoculating just 10 logs each year, one can harvest up to 25 pounds of fresh mushrooms each year.
