How to Grow Mushrooms: Using Liquid Culture to Make Grain Spawn
While liquid culture is great for bonus materials, it’s best to not rely on it for your primary means of generating grain spawn. For consistency, buying from a reputable seller or creating your own are the better options. Liquid culture often grows well, but contamination takes hold easily, and there’s a large risk of losing an entire batch of grow bags if it’s your main source of spawn. However, for a one time grow or trial run, the inexpensiveness of liquid culture helps equalize the risk.
