This Shiitake plug spawn pack contains high quality, fresh living mushroom grain spawn ready for inoculation at home. 

Using our spawn, it is extremely easy to grow mushrooms all the way to fruit or use it to start your own mother culture.

Our strains are specifically selected for their high yield, vibrant colours and strong flavours. Boasting an incredibly low generation number, this laboratory-grade grain spawn can’t be matched in terms of quality and reliability.

  • Suitable for all customers from hobbyists to professionals
  • A great first time grow, perfect for those interested in more than the traditional eating mushroom
  • Stunning colours on the fruiting body
  • Will bring harvests of mushrooms, year after year
