Soya Hull Pellets, made from the excess hulls of soya beans, work great as a supplement for mushroom production. It does this by binding as a substrate to produce faster growth and higher yields, perfect for supplementing growth for most of our range of gourmet mushrooms. Recommended to be mixed with Oak Hardwood Pellets or similar to make the most effective and nutritious substrate.


These pellets are very effective at soaking up water and are able to gain humidity in under one hour, almost doubling their volume. They are great at aerating substrate, allowing the mycelium to grow as quickly as possible.

Soya Hull Pellets

  • Can be hydrated by covering in water and letting to sit for 1 hour. Pasteurise/sterilise accordingly.


    We recommend adding other substrates such as oak hardwood pellets, straw pellets, bran, sunflower pellets, sawdust, gypsum or similar to increase the nutritive power of the substrate, resulting in a larger yield.


    Once pasteurised/sterilised the mixture can be used to inoculate mushrooms using our grain spawn.
