Pasteurized Mushroom Substrate Casing | 1 lb Bag Ready For Use

This listing includes one (1) 1-pound bag of Pasteurized Mushroom Casing—a high-quality, ready-to-use casing mix designed to support optimal mushroom growth.

To complement our sterilized mushroom cultivation products, we now offer premium mushroom substrate casing. Out-Grow’s casing mix is carefully formulated using select organic ingredients, including peat moss, vermiculite, pH buffers, stabilizers, gypsum, and other proprietary components. Each batch is extensively tested and refined to ensure the perfect balance of moisture, texture, and pH stability for reliable results.

Casing serves as a non-nutritious, moisture-retaining layer applied on top of your mushroom substrate. It helps regulate humidity, retain water, and create an ideal microclimate to promote even pin sets. Proper pasteurization and pH balancing are essential for casing effectiveness. Too much moisture can harm pin formation, while excessive dryness can negatively impact your substrate.

At Out-Grow, we guarantee the perfect moisture content in every bag, ensuring consistent and successful mushroom cultivation.
