Premium oak hardwood pellets, ideal for bulking out grain spawn or supplementing mushroom substrate with extra structure and slow-release nutrition. Made from 100% oak hardwood with no additives or binders, these pellets expand and break down naturally once hydrated, creating a dense, well-aerated growing medium.
 
Popular as a cost-effective bulk substrate component for oyster and other wood-loving species, or as a base layer beneath CVG mixes.
 
Available in 1kg, 5kg, 10kg and 25kg bags to suit hobby growers through to bulk production.
