Intended use

MushRealm Collective sells horticultural supplies for growing gourmet mushrooms: sterilized grain spawn, pasteurized coir-based substrate and kits that pair the two. They are used to grow culinary species such as oyster mushrooms, and our grain spawn suits lion's mane, shiitake and most other gourmet species.

  • Our products contain no mushroom spores, cultures or genetics. You supply the culture of the species you are growing.
  • They are not food and are not for human or animal consumption.
  • We do not sell, promote or give advice on growing any species that is controlled or illegal where you live. Customers are responsible for following the laws that apply to them.
  • We sell to adults aged 18 or over. The US menu ships to addresses in the United States and the UK menu ships to addresses in the United Kingdom.
