3lb Sterile Millet Grain Spawn Bag – Vacuum-Sealed with Injection Port
Our 3lb millet grain spawn bag is fully sterilized, vacuum-sealed, and equipped with a self-healing injection port for clean and efficient inoculation. Millet is a nutrient-dense grain with a high surface area, providing thousands of inoculation points to accelerate mycelial colonization and improve yield reliability.
Key Features
- 100% white millet—small grain, high nutrient content, fast colonization
- Sterilized at 121°C for 2.5 hours in a commercial autoclave
- Self-healing injection port for easy, clean inoculation
- Includes internal filter patch for optimal gas exchange
- Vacuum-sealed inside a secondary barrier bag for double-layer protection
- Longer shelf life when stored in a cool, dry place (45–70°F)
Quick Start Guide
- Inspect: Ensure bag is intact, fully sealed, and the filter patch is undamaged.
- Inoculate: Wipe injection port with 70% isopropyl alcohol. Inject 4–6 mL of liquid culture or spore solution using a sterile syringe.
- Shake: Once 20–30% colonized, gently mix the bag to redistribute mycelium for faster spread (optional).
- Incubate: Store bag upright at 70–75°F in a clean, dark area. Full colonization typically occurs in 10–18 days.
- Use or Store: Use immediately after full colonization or refrigerate for up to 2 weeks.
Storage Tips
- Keep between 45–70°F for maximum shelf life
- Avoid direct sunlight and excessive humidity
- Do not freeze

Awesome product, arrived fast and clean.
Great shipping time as always! Love you guys!
This was way better than a normal CVG! I usually pastuerize my own CVG but i had no coco coir left , so i just bought this substrste because i had spawn ready to go and this was the quickest way to get that going! The micelium grabbed hold much quicker with this substrate . I was very surprised and extremely happy. I would buy again
They are great
