Nutrient-rich soya hull pellets, a favourite bulk substrate additive for boosting yields on wood-loving mushroom species. High in protein and easily broken down once hydrated, soya hulls add valuable nutrition to grain-to-bulk transfers without the contamination risk of using loose hulls.
 
Combine with hardwood pellets or CVG substrate for a well-balanced bulk mix, or use on their own as a supplemented substrate base.
 
Available in 1kg, 5kg, 10kg and 25kg bags.
