Sterilized Red Milo Grain Spawn Bag – 3lb for Mushroom Cultivation

Out-Grow’s Sterilized Red Milo Grain Spawn Bag – 3lb is a high-volume, lab-prepared substrate ideal for growers who want fast colonization, multiple inoculation points, and consistent performance. Red milo is a small, efficient grain that promotes rapid mycelial expansion across a wide variety of mushroom species, making it a go-to choice for both home and commercial cultivation.

3lb Red Milo Mushroom Spawn Bag with Injection Port and Filter

Each grain spawn bag contains approximately 3 quarts of fully hydrated red milo grain, sterilized at 15 PSI in our professional mycology lab. A self-healing injection port allows for clean inoculation with liquid culture or spore syringes, while a 5-micron filter patch supports sterile gas exchange during colonization. The fine grain size of red milo creates more inoculation points, resulting in faster colonization and a more efficient growth cycle.
