STONE WOOL SLAB

The Begrow Stone Wool Slab is an ideal substrate for root system development in hydroponic conditions. Designed for vegetables, flowers, and other crops, it provides a stable and efficient growing environment in high-tech greenhouses.

Optimized Raw Material – Made from randomly arranged stone wool fibers, ensuring a rigid structure and extended lifespan for multiple growing seasons.
Superior Drainage – Vertically aligned fibers enhance drainage and oxygen flow, making the substrate drier and more efficient than alternatives with horizontal fiber arrangements.
Faster Root Growth – Promotes quicker and stronger root development compared to conventional substrates.

Reliable Moisture Control – Maintains optimal moisture retention while preventing shrinkage, meeting global industry standards.
