Bulk Vermiculite

This horticulture-grade vermiculite provides premium moisture and nutrient retention when used as a substrate additive. It also allows for greater aeration, an essential component for larger flushes and faster colonization. A2 fine-medium coarseness is ideal for mushroom cultivation, as it has greater water retention capacity and can be used for external casings. A thin layer can be added to the base of a fruiting chamber to increase ambient humidity.
