Premixed dry substrate bags for the cultivation of Blue, Pink, Yellow, Florida, Summer Oyster mushrooms and others. 
 
Our substrate formula is made up of a mixture of oak sawdust, soya hulls, straw, sunflower husks, bran and CaCO3 that has been tested by us to produce high yields. The substrate has optimum nutrient levels, speeding up growth of mycelium.
 
Once pasteurised (see Use Information), you can inoculate the substrate with grain spawn or other methods.
 
Note: These bags contain the dry substrate only, you will need to pasteurise the substrate before use. Each mixture contains different amounts of dry substrate to create the optimum substrate for the respective species.
 
We recommend that you take a look at our Hobbyist Growing Packs here if you wish to grow more mushrooms or if you want to grow mushrooms at home but you don't have the necessary knowledge.
