[header] How to grow mushrooms [title] Purchase oyster mushroom spawn. [step] Oyster mushrooms are the easiest to grow, and a great choice for novices. To get started, buy them online, in a home gardening store, or in a homebrew supply store in the form of " spawn ": spores or root-like mycelium stored in sawdust, grain, or agar. 
You can buy the spawn alone or as part of a complete oyster mushroom kit. Any oyster mushroom variety will work, but blue grey oysters and pink oysters are especially easy and quick to grow.
