How do you grow mushrooms?

Growing mushrooms is achieved in several successive steps, and is much more complicated than growing plants, generally. Mushrooms form from mycelium, which is the vegetative part of the fungus, and is generally white, but color can vary with species. As a cultivator of mushrooms, you will have to learn how to cultivate mycelium cultures effectively, and there are many perils on the path to doing so successfully. The main obstacle that most people run into is contamination of their mushroom cultures by competitor fungi. The most common contaminant is mold, but there are a few others, like bacteria and yeasts. Recently I have purchased Shiitake spawn from Agrinoon, who keeps working on the new technology to enhance the quality of the product.
