VitaLink Clay Pebbles are 8-20mm clay pellets that have a lower bulk density meaning they are lighter, leading to higher porosity and therefore, more water retention. VitaLink Clay Pebbles offer many benefits over competitors' products: 

VitaLink Clay Pebbles offer a tumbled surface without the sharp edges that can cut delicate roots and harm plants making them vulnerable to pests and diseases; these tumbled surfaces also ensures good root aeration (non-compaction). 

They are extremely stable in both pH and EC which helps to prevent excess acidity build up. Performance is excellent in Flood and Drain systems where oxygen exchange in thick root mass is essential. Strong structural integrity means that they are less likely to break and compact, which can lead to blocked dripper systems. 

They are pre-washed which aids in stability. The pebbles drain freely and do not hold any excessive water, which is why they provide good oxygen levels around the root and why they are particularly suitable for Flood and Drain systems. 

They are also used extensively for Multi Pot systems and drip-fed WaterFarm-type systems. Available in 50L and 10L bags
