Sterilized White Milo Grain Spawn Bag – 3lb for Mushroom Cultivation
Out-Grow’s Sterilized White Milo Grain Spawn Bag – 3lb is a lab-prepared substrate trusted by cultivators seeking clean, fast, and consistent mushroom production. White milo is a small, nutrient-rich grain ideal for maximizing inoculation points and promoting rapid mycelial expansion across a wide range of gourmet and medicinal mushroom species.
Professional 3lb Mushroom Spawn Bag with Injection Port and Filter
Each white milo grain spawn bag contains approximately 3 quarts of fully hydrated and sterilized grain, processed at 15 PSI in our professional mycology lab. The self-healing injection port allows for sterile inoculation with 6 to 12 cc of spore or liquid culture, while the integrated 5-micron filter patch provides optimal gas exchange throughout colonization. The smaller grain size of white milo encourages more even colonization and faster substrate takeover compared to larger grains.
Reliable Grain Spawn Substrate for High-Yield Mushroom Grows
This 3lb grain spawn bag is ideal for inoculating 10 to 15 pounds of bulk substrate once fully colonized. White milo’s natural density and high surface area create the conditions needed for uniform mycelial growth and strong yields. It’s a trusted choice among growers who want speed, consistency, and performance without the contamination risks of homemade alternatives.

Out-Grow has supplied professional-grade mushroom substrates to growers across the country for more than 15 years. Our sterilized white milo grain spawn bags reflect that same dedication to quality and consistency.
