We have been introducing mushroom cultivation as a nutritional supplement and cash crop for the landless poor. Oyster mushrooms are a high yield, fast growing crop. They are known to help lower cholesterol levels and are a great source of potassium, iron and protein.

This instructable gives a low tech, step by step guide to growing both pleurotus ostreatus (winter strain) and pleurotus pulmonarius (summer strain). Oyster mushrooms are highly tolerant of variations in temperature, humidity, light levels and carbon dioxide levels, making it a great choice for first time growers.
