Hydroton clay pebbles Available in $ Liters and 8 Liters Hydroton clay pebbles, also known as expanded clay pellets, are lightweight, porous, and often used in hydroponic systems or as a soil amendment in gardening. They are made from natural clay that is heated to high temperatures in a kiln, causing it to expand and form round, smooth, and pH-neutral pebbles. Here are some key features of Hydroton clay pebbles: 1, Porosity: The pebbles have a high surface area, which allows for good oxygen flow around plant roots and promotes healthy root development. 2, Water retention and drainage: While Hydroton holds moisture, it also drains well, preventing waterlogged conditions that can lead to root rot. This balance is crucial in hydroponic and aeroponic systems. 3, pH Neutral: Hydroton is chemically inert and does not affect the pH of the water or soil, which is important in hydroponic setups. 4. Reusability: Hydroton is durable and can be reused multiple times after cleaning, making it a cost-effective option for hydroponic growers. 5. Lightweight: Despite its ability to hold moisture and provide support to plants, Hydroton is lightweight, making it easier to handle and transport. Hydroton clay pebbles are commonly used in systems like deep water culture (DWC), drip irrigation, and flood-and-drain (or ebb and flow) setups. They are also used in aquaponics and as an additive to improve soil aeration in traditional gardening.
