Young plants start strong with this 75×75×65mm Stonewool Block. Balancing excellent moisture retention with plenty of oxygen around developing roots, Stonewool creates the ideal environment for healthy root development and vigorous plant growth.

Use It Your Way: Use block alone or insert a rooted 25×25×40mm Stonewool cube for easy transplanting.
Strong Starts for Growing Plants: Holds moisture and air to encourage healthy root systems.
About Stonewool
Stonewool is made by melting basalt and limestone rock, then spinning into fine fibres & compressing into cubes, blocks or slabs. The result is a sterile growing medium that balances moisture & airflow for healthy root development.
Getting Started
Pre-Condition: Soak block in pH 5.5 water before use (dissolves lime).
Pre-Soak Time: 30 seconds to 30 minutes, until evenly moist.
Don't Squeeze: Especially when wet (can damage fibre structure).
Water During Light Hours: Only water when plants are receiving light - never in the dark.
Water Wisely: Keep Stonewool moist, not waterlogged. Overwatering reduces oxygen around roots & may result in algae growth.
Handle Safely: We recommend wearing gloves & a dust mask when handling dry Stonewool, as fibres may cause temporary skin or respiratory irritation.
