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. Briefly wipe the needle and injection port with the swab, inject 3–5 ml – the mycelium does the rest for you. No autoclave, no transferring, no lab.\u003c\/p\u003e\n\u003cp\u003eThis bag is a good solution for beginners without prior knowledge who want to start growing mushrooms – without complicated preparation or special equipment. You need neither an autoclave nor a pressure cooker or lab equipment – simply inoculate, wait and harvest.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFewer steps, lower risk of contamination\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIn traditional mushroom growing, grain spawn and fruiting substrate are often prepared separately and mixed together later. That means more steps, more contact with the material and therefore a higher risk of contamination. Our all-in-one grow bag reduces these risks: from inoculation to fruiting, the bag stays largely closed. The mycelium first colonises the grain layer and then the hardwood substrate – all in the same sterile bag.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThree steps – from inoculation to harvest\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e1.

Let it colonise\u003c\/strong\u003e\u003cbr\u003eWait about 1 to 2 weeks until the mycelium has partly colonised the grain layer. Many growers wait until the grain is fully colonised, but that isn't necessary here. Then mix the bag carefully so that the mycelium can spread through the whole substrate.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3.

The success of your grow also depends on the quality of the inoculum, a clean inoculation technique and suitable conditions such as temperature and humidity. For good results we recommend using the bag as soon as possible after it arrives.
