A full 25kg sack of Doves Farm rye grain (rye berries) for larger-scale spawn production — the single-sack option for growers who don't need the smaller pick-a-quantity sizes on our standard rye grain listing.
 
Easily hydrated and clean to work with, this grain suits most gourmet mushroom species. If sterilising and hydrating 25kg yourself feels like a lot, we also sell fully sterilised, ready-to-inject Rye Grain Spawn Bags in smaller quantities.
