Out-Grow’s Sterilized Popcorn Grain Spawn Bag is a professionally prepared substrate designed for growers who want fast colonization and high moisture retention in their mushroom cultivation.

Superior Grain Spawn with Injection Port and Filter Patch
This grain spawn bag is fully sterilized, hydrated, and sealed in a gusseted grow bag with a 5-micron filter patch and a self-healing injection port.
