Sterilized Mega Mix Grain Spawn Bag – 1lb for Mushroom Cultivation
Out-Grow’s Sterilized Mega Mix Grain Spawn Bag is a professionally prepared 1lb substrate formulated for superior mycelial growth and diverse nutrient intake. This premium blend combines yellow popcorn, red milo, and rye berries—three high-performance grains known for their ability to support vigorous colonization across a wide range of mushroom species.
Multi-Grain Mushroom Spawn Bag with Filter Patch and Sterile Prep
Each grain type in our Mega Mix offers unique benefits: popcorn adds structure and moisture retention, red milo supports long, sustained growth, and rye berries provide balanced nutrition. Hydrated with clean spring water and sterilized for three hours at 15 PSI in our professional mycology laboratory, this blend ensures a clean, contamination-resistant start. The 5-micron filter patch allows for steady gas exchange, creating an ideal environment for healthy and rapid colonization.
