Sterilized Red Milo Grain Spawn Bag – 1lb for Mushroom Cultivation

Out-Grow’s Sterilized Red Milo Grain Spawn Bag is a professional-grade substrate designed for fast, efficient mushroom cultivation. With 1 pound of fully hydrated red milo grain sterilized in our commercial mycology laboratory, this grain spawn bag provides a clean, nutrient-rich medium ready for inoculation.

Lab-Prepared Mushroom Grain Spawn Bag with Injection Port and Filter

This 1lb red milo grain spawn bag includes a self-healing injection port for clean, hassle-free inoculation using spore syringes or liquid culture. A 5-micron filter patch ensures optimal gas exchange while maintaining a sterile internal environment, giving your mycelium the ideal conditions to colonize aggressively and evenly. Red milo is a favored grain for its small size, which provides more inoculation points and faster colonization than many other grain types.

Professionally Sterilized Red Milo Substrate for Consistent Results

Our red milo is hydrated with precision and sterilized at 15 PSI to eliminate contaminants and ensure substrate consistency. This 1lb grain spawn bag is equivalent to roughly 1 quart in volume and is suitable for inoculating smaller bulk substrates or for use in master spawn expansion. Each bag is produced in a controlled lab environment and reflects Out-Grow’s 15+ years of experience in mushroom substrate preparation.
