Sorghum (Milo) Grain Spawn Bag — 3lb | Sterilized & Ready to Inoculate

🌾 Uniform Grain, Reliable Colonization

Sorghum — also known as milo — is prized by mushroom cultivators for its small, hard, uniform kernels. That uniformity means an even hydration level throughout the bag and a high density of colonization points, giving mycelium more surface area to grab onto than larger grains like rye. Our 3lb sterilized sorghum spawn bag is prepped in a professional mycology facility and ready to inoculate the moment it arrives at your door — no sterilization equipment, no prep work, no guesswork.

📦 What You're Getting

• 3lb of fully hydrated, sterilized sorghum (milo) — properly moisture-balanced for optimal mycelial colonization
• Autoclave sterilized in a professional facility to eliminate contaminants before they become your problem
• Organic, sustainably sourced grain — quality ingredients from the start

✅ Key Features

• 🌾 Sorghum (milo) grain — small, uniform kernels with a tough hull that resists clumping and overhydration
• 🧪 Professional autoclave sterilization — no contamination headaches
• 🌿 Organic, sustainable ingredients — responsibly sourced
• 💉 Built-in self-healing injection port — clean inoculation without opening the bag
• 🌬️ 0.2 micron filter patch — reliable gas exchange that keeps contaminants out
• 📦 Ships fresh — we prep bags daily so what arrives at your door is always fresh and ready to perform

🌱 Who Is This For?

Sorghum's small, consistent grain size makes it a favorite for growers who want dense, even colonization and a grain that holds its structure well through multiple grain-to-grain transfers:

• Beginner growers — a forgiving grain that colonizes evenly with minimal fuss
• Experienced growers — a dependable choice for bulking up spawn or running grain-to-grain expansions

❓ How Do I Use It?

1. Flame-sterilize your needle and wipe the injection port with an alcohol swab
2. Inject your liquid culture or spore solution through the self-healing port
3. Store at room temperature in a dark location
4. Shake or break up the grain once partial colonization is visible to speed things up
5. Once fully colonized, transfer to your bulk substrate and initiate fruiting 🍄
