Mushroom plugs are a beginner-friendly way to grow mushrooms on logs. They are made of mycelium grown into hardwood dowels, which are then tapped into holes drilled into a log. The logs should be four to ten inches in diameter and two to five feet long. The best time of year to inoculate logs with mushroom plugs is in late winter, when logs have higher concentrations of sugar. Plugs are easy to use and require no special tools. They are durable and can be used to grow Shiitake, Oyster, Lion's Mane, Reishi, and other types of mushrooms.

Mushroom plugs are an easy way to grow mushrooms at home
The best time to inoculate logs with mushroom plugs is in late winter, when the logs have higher concentrations of sugar. However, some species, such as Oyster mushrooms, can be planted in late winter and may start fruiting in the fall of the same year. Other species, like Shiitake, have a longer incubation period of nine months to two years. Therefore, it is important to choose the right species for your needs and local climate.
To get started, you will need fresh logs or stumps that are four to ten inches in diameter and two to four feet long. Drill holes about six to eight inches apart down the length of the log, creating a grid pattern. Then, tap the mushroom plugs into the holes using a mallet or hammer. Seal the holes with wax to prevent the spawn from drying out.
Growing mushrooms using mushroom plugs is a rewarding experience that can provide you with seasonal crops for years to come. With the right tools and a basic understanding of mushroom growth, anyone can successfully grow mushrooms at home using this method. So, if you're interested in cultivating your own mushrooms, mushroom plugs are definitely worth considering!

The best time to inoculate logs with mushroom plugs is late winter
Mushroom plugs are hardwood dowels laced with mushroom mycelium that are plugged into freshly cut logs or stumps to inoculate them. The mycelium will start producing fruiting bodies after a full year of growing and can continue to produce every year for up to five years or more, depending on the log's decomposition rate.
The process of inoculating logs with mushroom plugs is quite simple and only requires a few tools. First, use a drill with a 5/16-inch drill bit to make holes about six to eight inches apart, starting about two inches from the end of the log. The holes should be drilled in a diamond pattern to ensure rapid growth of the fungus. Then, tap the plug spawn into the holes using a mallet or hammer, leaving space for sealing the holes. Finally, seal the plugs with wax to prevent the spawn from drying out and to create optimal conditions for mycelium growth.
It's important to note that the number of plugs per log will affect the speed of colonisation and the cost of spawn. The more plugs used, the faster the colonisation but the higher the cost. Additionally, the type of spawn used also impacts the speed of colonisation, with sawdust spawn being faster than plug spawn.

Mushroom plugs are made of mycelium-grown hardwood dowels
Mushroom plugs are an easy and beginner-friendly way to grow mushrooms on logs. They are ideal for small projects and are simple to use, requiring no special tools. The plugs are made of mycelium-grown hardwood dowels, which are tapped into holes drilled into a log. This method of mushroom cultivation mimics how mushrooms grow in the wild.
To get started, you'll need to gather some tools and fresh logs. The logs should be four to ten inches in diameter and two to five feet long. You'll also need a one-inch bristle paintbrush and a drill with a 5/16" bit or an 8.5mm bit. Drill holes about six to eight inches apart down the length of the log, creating a grid of holes in a diamond pattern.
Once you have your logs and tools ready, it's time to inoculate! Use your drill to create holes in the logs, and then tap your mushroom plugs into the holes using a mallet or hammer. Seal the holes with wax to prevent the spawn from drying out. The mycelium will start producing fruiting bodies after a full year of growing and can continue producing for five years or longer, depending on the log's decomposition rate.
The best time to inoculate logs with mushroom plugs is in late winter, when the logs have higher concentrations of sugar. Oyster mushrooms and Shiitake are great species to start with. Oysters have a shorter incubation period and can start fruiting in the fall of the same year they are planted. Shiitake has a longer incubation period, typically taking nine months to two years to produce mushroom bodies.

Mushroom plugs are an easy and beginner-friendly way to grow mushrooms on logs. They are hardwood dowels laced with mushroom mycelium, which are plugged into freshly cut logs or stumps to inoculate them. The mycelium will start producing fruiting bodies after a full year of growing and can continue to produce for up to five years or more.
You can buy pre-made mushroom plugs from various online vendors, including Cascadia Mushrooms, Mushroom Mountain, North Spore, FreshCap Mushrooms, Fungaia Farm, and Amazon. Buying plugs is a good option if you are new to growing mushrooms, as it is a simple process that does not require any special tools. However, if you want to try to complete the growing process from scratch, you can also make your own mushroom plugs at home.
Making your own mushroom plugs is fairly easy, especially if you have some experience with growing mushrooms. You will need hardwood dowels, which can be found at hardware stores or craft shops, and a mushroom culture to inoculate the plugs. Suitable species include Oyster, Lion's Mane, Shiitake, and Reishi. You can use grain spawn, wedges of mycelium on agar, or liquid culture syringes for inoculation. It is recommended to sterilize the dowels before inoculation, either by using a pressure cooker or by boiling them in hot water. Once the dowels are cooled, you can inoculate them with your chosen mushroom culture.
After you have your mushroom plugs, you will need fresh logs or stumps to inoculate. The logs should be four to ten inches in diameter and two to five feet long, and the stumps should be two to four feet tall. Use a drill bit to create holes in the logs or stumps, and then tap the plugs into the holes using a mallet or hammer. Seal the holes with wax to prevent the spawn from drying out, and wait for your mushrooms to grow!

Mushroom plugs are ideal for growing Shiitake, Oyster, and Lion's Mane mushrooms
Mushroom plugs are small pieces of wood that have been inoculated with mushroom mycelium. They are inserted into logs or stumps to grow mushrooms. Plugs are the most basic way to grow mushrooms on logs and are ideal for beginners or those who only want a few logs of a particular species.
Shiitake mushroom plugs are a popular choice for those interested in growing their own mushrooms. Shiitake mushrooms produce medium-to-large, brown, umbrella-shaped caps and have a rich, savory, buttery, and umami flavor. They tend to produce generous flushes and colonize quickly, making them a great option for beginners. Shiitake works best with the log method, preferably using oak, maple, or beech wood. Colonization takes at least 9-12 months, and fruiting tends to occur throughout the summer and fall growing seasons, especially after rainfalls.
Oyster mushroom plugs, specifically Blue Oyster, are also a popular choice for growers. Blue Oyster mushrooms are a subspecies of Pearl Oyster, native to Western Europe, and thrive in cooler temperatures. They exhibit a notable blue-gray hue with darker caps and pale gills, giving them a stunning appearance. Oyster mushrooms can be grown on softer hardwoods like tulip poplar, and oak is recommended for other species.
Lion's Mane mushroom plugs are another option for growers. Lion's Mane mushrooms produce plump white clusters with icicle-like teeth and have a flavor and consistency similar to crab meat when cooked. They are slightly harder to get flushes than oysters or shiitake, but they are still a great outdoor mushroom for intermediate growers. Lion's Mane prefers maple but can grow on many hardwood species.
Overall, mushroom plugs are an ideal way to grow Shiitake, Oyster, and Lion's Mane mushrooms, especially for those who are just starting out with mushroom cultivation.
