Sterilized Grain Spawn Bag – 3 lbs (50% Hydration)
This 3-lb sterilized grain spawn bag is built to give your mushrooms a fast, even start. It’s prepped at a target 50% moisture content with a balanced mix of organic millet and wheat berries—hydrated, nutrient-rich, and ready for inoculation. All you need is a spore syringe or liquid culture.
Each bag includes:
A self-healing injection port (color may vary) for clean inoculation.
A 0.2 micron filter patch that allows steady gas exchange while blocking contaminants.
Why millet matters:
Millet carries a lower endospore load than rye or wheat, which means fewer chances of contamination. Its small grain size gives you more inoculation points, allowing mycelium to spread faster and more evenly. Paired with the nutrient content of both millet and wheat, this blend supports vigorous colonization.
Sterilization standards:
Bags are sterilized in a commercial-grade autoclave, with sterility verified by biological indicators and temperature sensors. That ensures the grain you’re working with is clean and reliable.
Usage tips:
For inoculation, use 2.5–5 cc of spore or liquid culture per 3-lb bag.
Once colonized, use 1 lb of spawn per 5 lbs of bulk substrate (manure or hardwood).
Always handle with sterile technique to protect your grow.
This is the same setup I’d hand to someone starting a grow in the lab—straightforward, forgiving, and designed for consistent results.
