Sinclair Vermiculite Medium 100L

Sinclair Vermiculite is a naturally occurring, non-toxic mica mineral expanded under high heat to form a lightweight, sterile, laminated structure. Ideal for propagation and soil conditioning, it offers excellent water retention and aeration properties.

With a particle size range of 2.0–5.0mm and water holding capacity of 381ml per litre, it improves drainage while retaining moisture and nutrients at the root zone.

Vermiculite also acts as an insulator, helping to stabilise soil temperatures and protect delicate seedlings.

Perfect for professional growers and horticulturists seeking consistent, reliable performance in a growing medium.
