Mushroom plugs are used in two distinct ways: to repair punctures in tubeless tires and to grow mushrooms. Mushroom repair plugs are pushed through the puncture and glued to seal the inside and outside of the tire. This is considered a permanent repair. Mushroom plugs for growing mushrooms are spiral-grooved hardwood dowels infused with a specific mushroom species. These plugs are hammered into holes drilled into freshly cut hardwood logs, stumps, or rounds to create a fruiting mushroom colony.

Mushroom plugs are used to repair punctures in tubeless tires
Mushroom plugs are a type of repair kit used to fix punctures in tubeless tires. They are considered a more stable and permanent repair method compared to string or cord plugs. The mushroom plug seals the puncture by being pushed through the tire and creating a patch on the inside and outside of the tire. This dual seal prevents air and moisture from migrating into the rubber layers of the tire, which could cause rust on the steel belts.
Mushroom plug repair kits typically include larger nozzles and probes required for installation. The plugs themselves measure approximately 1" tall with a 7/16" diameter stem, and the mushroom head is about 13/16" wide, similar in size to a US quarter. This larger size makes it suitable for repairing more serious punctures in both on-road and off-road vehicles with tubeless tires.
To install a mushroom plug, the tire must be removed, and a special tool is used to ram the plug through the puncture. The process is considered more complex than a string plug repair, which can be done externally without removing the tire. However, mushroom plugs are favoured by some puncture repair shops because they provide a longer-lasting and more effective fix.
While mushroom plugs are a popular choice for tubeless tire repair, they are not the only option. Cord plugs, for example, have been used for decades and can last for tens of thousands of miles when properly installed and maintained. Some people question whether the preference for patch repairs is perpetuated by the tire industry to generate more business for tire shops.
In conclusion, mushroom plugs are a reliable and durable solution for repairing punctures in tubeless tires. While they may require more time and equipment than some alternative methods, they offer a stable and permanent repair that can handle larger punctures in a variety of vehicles. For those seeking a robust solution to tubeless tire punctures, mushroom plugs are a recommended option.

They are considered a more stable and permanent repair than string plugs
Mushroom plugs are used to repair punctures in tubeless tires. They are considered a more stable and permanent repair than string plugs. Unlike string plugs, mushroom plugs are pushed through the puncture and glued, with a rubber plug and patch built into them. This seals the inside of the tire to the outside, preventing air and moisture from migrating into the rubber plies of the tire. This also prevents water from entering and rusting the steel belts.
While string plugs can be repaired externally without removing the tire, mushroom plugs require tire removal. This makes mushroom plugs less DIY-friendly than string plugs. However, the latter may develop a slow leak as the tires wear down, which is not an issue with mushroom plugs.
Mushroom plugs are also used in agriculture to grow mushrooms. Mushroom plug spawn is spiral-grooved hardwood dowels infused with a specific mushroom species. These plugs are hammered into holes drilled into freshly cut hardwood logs, stumps, or rounds. This process creates a fruiting mushroom colony that can produce mushrooms for many years.
Overall, mushroom plugs offer a more durable and long-lasting solution for repairing punctures in tubeless tires compared to string plugs. While they may be less convenient due to the need for tire removal, they provide a superior seal and prevent issues like slow leaks.

They seal the inside and outside of the tire, preventing water from getting in
Mushroom plugs are used to repair punctures in tubeless tires. They are considered a more stable and permanent solution than string or cord plugs. The plug is pushed through the puncture and has a rubber plug and patch built into it. Once pulled through and glued, the inside of the tire is patched and sealed, and the outside is also sealed.
A mushroom plug seals the inside of the tire to the outside. This means that water cannot get in and cause damage, such as rusting the steel belts. This is achieved through the use of a special sealant around the plug, which keeps air and moisture from migrating into the rubber plies of the tire.
To install a mushroom plug, a larger nozzle and probe are required. This repair method is not considered DIY-friendly, as it is more complex and requires the removal of the tire. It is also not possible to repair a tire with mushroom plugs on the side of the road.
Mushroom plugs are available in kits, such as the Stop & Go 1080 Tubeless Mushroom Plug Tire Repair Kit, which can be used to repair larger punctures in all tubeless tires. Each mushroom plug in this kit measures 1" tall with a 7/16" diameter stem, and the mushroom head measures approximately 13/16" wide, about the size of a US quarter.
In addition to repairing tires, mushroom plugs are also used in mushroom cultivation. Mushroom plug spawn are spiral-grooved hardwood dowels infused with a specific mushroom species. These plugs are hammered into holes drilled into freshly cut hardwood logs, stumps, or rounds. This process creates a fruiting mushroom colony, commonly referred to as a mushroom log, which can produce mushrooms for many years.

Mushroom plugs can be used to inoculate hardwood logs to grow edible mushrooms
Mushroom plugs, also known as plug spawn, are spiral-grooved hardwood dowels infused with a specific species of mushroom. The mushroom mycelium (the white, root-like network of cells) colonizes and penetrates the dowels as it consumes the lignins provided by the wood. These plugs are used to inoculate freshly cut hardwood logs, stumps, or rounds to create a fruiting mushroom colony that can produce mushrooms for many years.
To inoculate the logs, you will need to prepare the plug spawn inoculation sites by drilling holes in a spiral pattern, starting at one end of the log and working towards the other. The recommended size of the holes is 5/16" x 1 1/2", and they should be spaced approximately 4-6 inches apart, with a total of 20-30 holes per log. After drilling, hammer the colonized plugs into each hole, using a small punch to sink the top of the plug about 1/4" below the bark surface.
To ensure the success of your mushroom colony, it is important to seal the inoculation sites. This can be done by dripping melted cheese wax or a natural food-grade wax sealant onto each hole. This will prevent competing organisms from entering the hole and help retain moisture. With proper care and maintenance, your inoculated logs will produce mushrooms several times a year for 3-5 years.

Mushroom plug spawn is spiral-grooved hardwood dowels infused with a specific mushroom species. The mushroom mycelium (the white, root-like network of cells) colonizes and penetrates the dowels as it consumes the lignins provided by the wood. These plugs are used to inoculate freshly cut hardwood logs, stumps, or rounds to create a fruiting mushroom colony that can produce mushrooms for many years. These colonies are commonly referred to as mushroom logs.
To inoculate your own logs, you will need recently cut, disease-free hardwood logs of approximately three feet in length and four to six inches in diameter. For those in North America, common deciduous trees such as elms, beech, and maples are good options. Use disease-free wood with the bark intact.
Prepare the plug spawn inoculation sites by drilling 5/16" x 1-1/2" holes in a spiral pattern, starting at one end of the log and working towards the other. Space each hole approximately 4-6 inches away from the last. The number of holes will vary, but for most logs, 20-30 holes are good.
