One inch rockwool cubes for propagation

These listings feature a pack of fifty rockwool starter cubes designed for the initial stages of plant growth. Each cube measures one inch and is made from stonewool, a material known for its excellent water retention and aeration properties. These plugs are commonly used for starting seeds or rooting cuttings before they are moved to a larger system.

The fibrous texture of the rockwool provides a secure environment for delicate new roots to take hold. Because the material is inorganic and sterile, it helps minimize the risk of soil-borne diseases during the vulnerable germination phase. The cubes are easy to handle and can be placed directly into net pots or larger growing media once the plants are established.

This set is a fundamental component for any soilless cultivation setup. The uniform size of the plugs ensures consistency across a tray of seedlings. Whether used for cloning or starting from scratch, these rockwool cubes offer a reliable medium that balances moisture and air, which is critical for successful plant propagation in hydroponic environments.
