Product Description – Clay Pebbles (Hydroton / Expanded Clay Pellets) Clay pebbles, also known as Hydroton or Expanded Clay Pellets, are lightweight, round, and highly porous growing media made from natural clay that is heated at high temperatures. This process creates a hard outer shell with a porous interior, making the pebbles strong, reusable, and excellent for air and water circulation. The product is available in three size grades – 1–4 mm, 4–8 mm, and 8–16 mm, allowing users to choose the most suitable option for their specific application. The pebbles have a rough, porous surface that promotes root aeration while retaining enough moisture to support healthy plant growth. Clay pebbles are chemically inert and pH neutral, ensuring they do not alter the nutrient balance or acidity of soil or hydroponic solutions. They are clean, low-dust, and environmentally friendly, making them ideal for both indoor and outdoor use. Available pack sizes: 1 L, 5 L, 10 L, 20 L, and 30 L.
