3kg Sterilized Sawdust Substrate Bag

This is a 3kg block of sterilized substrate in a unicorn mushroom growing bag with 5 micron filter patch.

Choose from a variety of supplemented substrates or plain hardwood sawdust. See below to check out what substrates are best for what kinds of mushrooms.

Master's Mix:

This is the industries tried and true golden standard for growing hardwood mushrooms. It's a hardwood sawdust substrate that is supplemented with soy hulls and added minerals to support healthy mushroom growth. This is a blend of substrate that has been used for decades with a robust history of large yields.

This type of substrate is typically used for growing soft bodied mushroom varieties like Lion's Mane, Oyster Mushrooms, Chestnut Mushrooms, Enoki Mushrooms, Shiitake and much more!

Un-supplemented:

A hardwood sawdust substrate with added minerals to support healthy mushroom growth. This is a very standard substrate and is much less prone to contamination than other substrates. 

All hardwood loving mushrooms will be compatible with this blend but it is highly recommended for use when growing Turkey Tail or Reishi Mushrooms for best results as they do not like the supplemented blends as much.
