VitaLink Clay Pebbles, 10l

The Clay Pebbles by VitaLink are granules (8-20mm) perfect for growing plants in hydroponic systems. The lower amount of clay pellets means they're lighter and retain more water and air. The pebbles have an uneven surface with no sharp edges, which could harm fine hair roots and endanger the plants.

 Adding clay pebbles (hydroton) to the substrate makes it more aerated and keeps it from getting too acidic. The hydroton is prewashed and doesn't affect the pH and EC levels. These qualities make them the perfect basis for hydroponic and aeroponic systems, where the roots need to stay aerated, and the solution needs to keep its pH level stable. 

The firm inner structure of the pellets keeps them from fracturing and crumbling, which would make the growing media more compact and dense. Hydroton doesn't retain any excess water, which makes the air distribution around roots optimal.

For best results, wash the pebbles with clean water before you use them. The growing media is reusable if washed before each use.
