The bag contains everything you need: sterilised wheat grains at the bottom as the nutrient base for the first colonisation phase, and on top a hardwood substrate with nutrient-rich wheat bran. Everything is already layered, moistened and processed under sterile conditions, so that you can achieve good yields under suitable conditions. No transferring, no mixing, and you don't need your own autoclave. All you have to do is inject 3 to 5 ml of liquid mycelium culture.\u003c\/p\u003e\n\u003cp\u003eIt's that simple: all you need is a liquid culture and an alcohol swab.
