Collection: Wholesale Pellets For Mushroom Substrate Production

Master mix combi pellets include soy hulls, which raises the nitrogen content of the substrate and generally drives faster colonisation and heavier yields on gourmet species. Straight oak is cheaper per tonne and suits growers blending their own mix, or growing species that do not want the extra nutrition, like shiitake. If you already run our master mix substrate bags, the master mix pellet is the like-for-like.

At our 20% oak, 20% soy hull, 60% water recipe, a tonne of oak pellets makes roughly 5,000kg of finished master mix substrate. A tonne of master mix pellets at 40% pellets to 60% water makes roughly 2,500kg of masters mix substrate.

indefinitely, but pellet quality will slowly degrade over time. These pellets are made fresh from order.
