The FRF RockGro is a specialized stone wool (rockwool) growing medium developed by Fujairah Rockwool Factory (FRF) for hydroponic and soilless cultivation systems. It is manufactured by spinning molten basalt rock into fine fibers, creating a structured medium ideal for plant growth.

RockGro is engineered to provide optimal water retention, aeration, and root support, ensuring healthy and uniform plant development. Its high porosity and capillary structure allow efficient distribution of water and nutrients while maintaining proper oxygen levels around plant roots.

The medium is chemically stable, sterile, and free from harmful substances, reducing the risk of diseases, pests, and contamination. It maintains a balanced pH range (typically 5.5–6.5), making it suitable for a wide variety of crops and hydroponic systems.

FRF RockGro is lightweight, easy to handle, and available in various shapes and sizes to support different stages of plant growth, from seeding to full cultivation. It is widely used in greenhouses, vertical farming, and commercial hydroponic agriculture.
