AgroGardens clay pebbles are highly porous medium, which limits watering and stimulate the development of strong roots that grip the substrate well. They are ideally suited for recirculating hydroponic systems.

As the pebbles are round and have a very even shape is excellent at offering plenty of opportunity for trapping air that provides excellent oxygenating any nutrient solution that flows over it and provide a strong structure and stable base for plant roots while allowing water to drain freely.

• Highly porous medium, which limits watering and stimulate the development of strong roots that grip the substrate well.
• Pebbles are round 10 – 16 mm.
• Offering plenty of opportunity for trapping air that provides excellent oxygenating any nutrient solution that flows over it and provide a strong structure and stable base for plant roots.
• Allowing water to drain freely.
• Helps to control the application of nutrients and the humidity levels of the plants.
• Are fungus free and do not rot.
• PH level is 5.5 – 7.
• Perfect for using in Flood and Drain systems, Multi-pot systems and drip-fed systems. They can also be used to mix with other substrates to improve structure, or to add a drainage layer in the bottom of pots.
