The smallest kernel we carry — and the highest surface-area-to-volume ratio of any grain in our lineup. More surface area means more contact points for mycelium to establish from, which is why millet consistently colonizes faster than rye or corn at the same inoculation volume. It also carries a naturally lower endospore load than larger grains, giving mycelium a cleaner head start against competing microbes.
The tradeoff is handling: millet's small, light kernels shift and settle more than larger grains, so a gentler hand when massaging the bag pays off in more even coverage. Every bag is sterilized in a commercial autoclave at 15 PSI and batch-tested with biological indicators before it ships. Recommended for growers past their first few grows.
Each bag: 3lb sterilized millet · 0.2-micron filter patch · self-healing injection port · shrooms instruction card. Store cool and dark until use.
