Expanded Fine Vermiculite 10 l

Fine Expanded Vermiculite 10 L specially selected for mushroom cultivation and spore incubation. It is an inert material that, while not providing nutrients, plays a key role in controlling moisture and oxygenation of the substrate.

Thanks to its neutral and constant pH, vermiculite promotes a stable environment for mycelial development, preventing abrupt changes that could affect growth. Its large water retention capacity (400–500 ml/L) maintains the necessary moisture over long periods, while its light and airy structure prevents compaction.

Besides its use in mycology, this vermiculite is suitable as a safe substrate for terrarium animals, offering a dry, stable environment free of toxic compounds.

• Dry matter: 100 %
• Conductivity: 0 mS/cm
• Water retention: 400–500 ml/L
• pH: 7.0–8.0
• Granule size: 1–3 mm
• Format: 10 L bag (approx. 2 kg)

Ideal for substrate mixes, casing layers or humidity chambers in mushroom cultivation. Also suitable for terrarium use and as a natural insulator in other horticultural and breeding projects.

Vermiculite is used in mushroom cultivation to retain moisture, improve aeration and stabilize the substrate environment, thereby promoting mycelial growth and mushroom production. It is very common in both home and professional methods due to its effectiveness and ease of use.

Uses of vermiculite in mushroom cultivation:

1. Moisture retention:
   Vermiculite can absorb and retain large amounts of water, which helps maintain a humid and consistent environment, essential for mycelium growth and mushroom fructification.

2. Improves aeration:
   Its porous structure allows good air circulation in the substrate or casing, preventing compaction and promoting healthy mycelial development.

3. Microclimate control:
   Helps maintain appropriate relative humidity in the cultivation environment, especially in closed systems or jars, such as those used for Psilocybe cubensis cultivation or home kits.

4. Casing component:
   In many techniques, vermiculite is mixed with peat, coco or lime to form a top layer over colonized substrate. This layer stimulates fructification and protects the mycelium.

5. Thermal insulation:
   Although not its primary function, its capacity to thermally insulate can also help maintain stable substrate temperatures.
