A tough, economical spawn grain.
Triple-cleaned red sorghum (milo) for grain spawn, in a 40 lb bag. Milo's small kernels create more inoculation points than rye, its tough hull holds up through long sterilization cycles, and white mycelium stands out clearly against the red hulls so you can track colonization.
Small kernels spread mycelium from more starting points.
Kernels stay intact through long pressure cycles.
White mycelium contrasts with red hulls.
A cost-effective base for high-volume spawn.
Rinse the milo until the water runs mostly clear, soak overnight, then simmer briefly. Stop before kernels split.
Drain and spread the grain out until the outside of each kernel looks dry.
Load filter-patch bags or jars and pressure sterilize at 15 PSI: about 2.5 hours for quarts and 1-3 lb bags, up to 3-3.5 hours for bigger loads.
Let it cool fully, ideally 12-24 hours, then inoculate with sterile technique.
Grain spawn must be sterilized, not just pasteurized. Start timing once the load is actually up to temperature. Most gourmet species colonize best at 75-82°F.
Short on time?Skip the prep with sterilized grain spawn bags or colonized grain spawn. Inoculate with our liquid culture syringes.
Yes. Grain spawn needs full sterilization at 15 PSI. Boiling or pasteurizing is not enough.
About 2.5 hours at 15 PSI for quart jars and 1-3 lb bags, and up to 3-3.5 hours for larger loads.
It was overcooked or too wet. Simmer briefly, stop before kernels split, and dry the surface before loading.

Red Sorghum is fresh and bug-free!
This was the cleanest sorghum I’ve ever bought. The quality is superb! I’ll definitely be buying again
These sorghum grains arrived within a few days of my order, extremely fast shipping. These grains are very good, very well cleaned. I found, from one of the employees, that these are human grade. I use these for myself, quite happy with the purchase.
