Horticulture grade hydroponic clay pebbles made of all-natural clay is used extensively in hydroponic grow systems and grow mixes.
Neutral pH and chemically inert: Agri is specifically formulated to be chemically inert with a neutral pH, and is therefore highly compatible with all types of plants and crops.
Air and water reservoir: Its high total porosity gives very good root ventilation and oxygenation to plants, whilst its high hydric retention (approx. 30%) makes it a valuable humidity reservoir: water is stored in the internal porosity of the clay granules and is slowly released to the plants.
Excellent draining capacity: Its dense network of inter granular voids of high drainage capacity prevents water from stagnating.
Lightweight: Its low density (approx. 330 kg/m3) is particularly appreciated in green roof systems and roof gardens because it reduces loading on the structure, and is widely used to the preparation of substrates to improve their physical characteristics.
Mineral, rot-proof, and non-combustible: As a 100% mineral product it will not rot, cannot be attacked by parasites (fungus, rodents, insects, etc.), is not conducive to the spread of plant diseases, is completely non-combustible, fire-resistant, and safe, including in the presence of fire.
Stable and durable: It is dimensional stable and non-deform able. It Is not adversely affected by freeze/thaw cycles, is resistant to acids and bases, and retains its properties unaltered over time; for all practical purposes this material will last forever.
Insulating characteristics: Its low thermal conductivity reduces sudden temperature changes in the substrate and increases the thermal resistance of green roof systems.
DRAINAGE AND MOISTURE RETENTION: Ideal as a lightweight draining layer in roof gardens and green roofs (both extensive and intensive), tubs, planters, vases, or in natural soil. It prevents water stagnation and acts as a valuable water reserve for plants, without increasing the weight of the structure.
GROWTH SUBSTRATE: can be mixed with the other components of a growth substrate (peat, compost, etc.) to improve its physical and chemical properties (humidity control, aeration, dimensional stability, lightness, durability,etc.).
HYDROPONICS AND AQUAPONICS: Ideal inert substrate for hydroponic and aquaponic crops, thanks to its standardize chemical and physical characteristics, its excellent insulating characteristics, which reduce sudden temperature changes, its freedom from phytotoxic substances, and its resistance to crushing. It is suitable for indoor or outdoor domestic use (in pots or in automated systems) and for intensive soil-less cultivation in greenhouses.
