Vermiculite for Mushroom Substrates

Vermiculite is a naturally occurring mineral that has been expanded at high temperatures to create lightweight, absorbent flakes. In mushroom cultivation, it is primarily used to manage moisture levels within a substrate and to provide necessary structure. It is a standard component for creating CVG (Coir, Vermiculite, Gypsum) mixes, as it holds water while still allowing for the aeration needed for healthy mycelial growth. Available in 3-litre and 8-litre bags, this horticultural-grade mineral helps prevent your substrate from drying out over multiple flushes, helping achieve professional mycology made simple.

Key Features:

• High moisture retention: Absorbs and holds water to provide a consistent hydration source for your mycelium.

• Improved substrate structure: Helps to prevent compaction within the media, allowing for better oxygen exchange.

• Natural and inert - A mineral-based additive that does not alter the nutritional balance of your substrate.
