Mushroom Cultivation

When available it is best for Mushroom Farms. No chopping Required – Stores well.

Cellulose Waste – Increase density by filling spaces between other material used – Traces of oil increase nutrition too.. – Increased water holding capacity –

Cotton seed hull is one of the most efficient substrate materials for Oyster mushroom cultivation. It is easy to dry so can be stored for relatively long period of time. It is more suitable for sterilize or pasteurize of Substrate because it emits extra heat by itself.

It generally contains 10% water & 90% matter that consist of 3.7% crude protein, 1.5% crude fat, 44% crude fiber, 35% soluble carbohydrate, and 3% ash etc.

Its C : N ratio is about 59 : 1. This chemical composition shows how nutritious a raw material cotton seed hull can be when cultivating oyster mushrooms. Thanks to its soft texture, High water holding capacity and good physical structure – Cotton Seed Hull is used worldwide as a good substrate.
