Excellent Air & Water Balance

VIVOSUN Rockwool Cubes feature approximately 95% porosity, allowing roots to access plenty of oxygen while the material retains moisture. This combination creates a favorable environment for developing roots and helps support vigorous early plant growth.

Sterile & Water-Retaining

The rockwool is inorganic and sterile, providing a clean growing medium that does not provide a suitable environment for harmful fungi. Its water-retaining structure helps keep roots hydrated while maintaining the moisture needed for nutrient uptake in hydroponic systems.

Easy Seed Starting & Propagation

Each cube includes a pre-formed opening for placing seeds or cuttings. The lightweight material is easy to handle and can be cut into different sizes when needed.

Once roots have developed, the cubes can be transferred into another growing medium or hydroponic system without disturbing the developing root structure.

Versatile Hydroponic Growing Medium

These rockwool cubes are suitable for a wide variety of applications, including hydroponic growing, seed starting, plant propagation, cloning, and rooting cuttings. Their soil-free design makes them convenient for growers looking for a clean and easy-to-manage propagation medium.
