Our Organic Rye Grain (also known as Rye Berries) is the preferred choice for professional mycologists and dedicated hobbyists alike. Its unique structure allows for maximum moisture absorption while remaining as individual grains—providing thousands of "inoculation points" for your mycelium to jump from.


Why Rye Berries?
Superior Moisture Retention: Rye can absorb nearly its own weight in water without the husk bursting, keeping your mycelium hydrated for weeks.
Optimal Nutrient Profile: Rich in nitrogen, phosphorus, and potassium—the exact fuel needed for aggressive colonisation.
Easy "Shake-ability": Unlike rice or wheat, rye doesn't easily clump. This makes "breaking and shaking" your jars much easier, speeding up colonisation times by up to 30%.
Clean & Fungicide-Free: Because it’s sourced from food grade and organic, there are no chemical residues that could inhibit sensitive fungal growth.
