Laterlite Agri: Expanded Clay Pebbles For Plants, Hydroponics And Growing
AGRI: EXPANDED CLAY PEBBLES FOR PLANTS, HYDROPONICS AND GROWING
AGRI: EXPANDED CLAY PEBBLES FOR PLANTS, HYDROPONICS AND GROWING
Laterlite Agri special expanded clay pebbles for plants, hydroponics, drainage, gardening and growing in general are produced in a specific way to be chemically inert and pH neutral, which gives them chemical and physical characteristics suitable for all the applications in contact with plants.
Laterlite Agri Expanded Clay pebbles are derived from the expansion of special natural clays at high temperatures. In addition to granular expanded clay, known as pebbles or grow rocks, Laterlite Agri is also available in a crushed version.
CHARACTERISTICS AND ADVANTAGES
LIGHTWEIGHT GROWING MEDIUM
Agri clay pebbles 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, ROTPROOF, AND NON-COMBUSTIBLE
As a 100% mineral product Agri pebbles will not rot, cannot be attacked by parasites (fungus, rodents, insects, etc.), are not conducive to the spread of plant diseases, are completely non-combustible (Euroclass fire rating – A1), fire-resistant, and safe, including in the presence of fire.
INSULATING CHARACTERISTICS
Agri expanded clay pebbles low thermal conductivity (lambda [λ] 0.09 W/mK) reduces sudden temperature changes in the substrate (thermal shock), protects the plants roots of from frost and heat peaks and increases the thermal resistance of green roof systems.
NEUTRAL PH AND CHEMICALLY INERT GROWING MEDIA
Agri Expanded Clay Pebbles are specifically formulated to be chemically inert with a neutral pH, and are therefore highly compatible with all types of plants and crops, both in traditional and hydroponic cultivation and they are suitable for all gardening, landscaping and horticultural applications,
EXCELLENT DRAINING CAPACITY
Agri clay pebbles dense network of intergranular voids of high drainage capacity prevents water from stagnating and root diseases.
STABLE AND DURABLE
Agri pebbles are dimensionally stable and non-deformable. They are not adversely affected by freeze/thaw cycles, are resistant to acids and bases, and retains their properties unaltered over time; for all practical purposes this material will last forever.
A NATURAL AND CERTIFIED PRODUCT
The natural origin of Laterlite Agri, combined with its manufacturing process, which respects the environment, make it a highly sustainable product. It is also certified for use in sustainable construction by ANAB-ICEA, the Italian Accreditation Institute.
AIR AND WATER RESERVOIR
Agri Expanded Clay pebbles high total porosity (approx. l’85% by volume) gives very good root ventilation and oxygenation to plants, benefiting plant health. At the same time, their high hydric retention (approx. 30%) makes them a valuable humidity reservoir: water is stored in the internal porosity of the clay granules and is slowly released to the plants making this product an ideal regulator of the amount of water needed by the plant element at any given moment.

CONSIGNMENT
Laterlite Agri is available in granular version (expanded clay pebbles or grow rocks) 3-8 and 8-20 or crushed versión 2-4 FRT and 5-12 FRT. All granulometries can be supplied in bulk, big bags or silo trucks equipped for on-site pumping (where logistically possible) offering the most suitable way to meet the needs of the site or the user. In addition, Laterlite Agri 3-8 Expanded Clay pebbles are available in 50 litre bags (75 bags per pallet – 3.75 m3) and 8-20 pebbles are available in both 50 litre bags (75 bags per pallet – 3.75 m3/pallet) and 10 litre bags (110 bags per pallet – 1.1 m3/pallet).
APPLICATION
HYDROPONICS AND AQUAPONICS
Laterlite Agri is the ideal inert substrate for hydroponic and aquaponic crops, thanks to its standardisable 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 soilless cultivation in greenhouses, for which the specific product IdroLaterlite in grow-bags (in 33.3 litre bags) can also be used.
DRAINAGE AND MOISTURE RETENTION
Laterlite Agri expanded clay is 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. Laterlite Agri is used by placing a layer of the material, in the desired grain size, of variable thickness (not less than 5 cm), below the growing medium on a roof, in a container, or in a planting pit
FOR IMPROVING GARDEN APPEARANCE AND MULCHING
A layer of 3/8 or 8/20 Agri clay pebbles (of recommended minimum thickness 10 cm) placed on top of the soil at the bottom of plants will hinder the growth of weeds, minimise loss of humidity from the substrate due to evaporation, reduce plant water stress and summer watering frequency, protect the soil from erosion and sudden temperature changes, and will give the garden a more orderly appearance. It is ideal for use with plants in pots, planters, outdoors, in roof gardens, vegetable gardens, or on green roofs.
GROWTH SUBSTRATE
Laterlite Agri 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.). It is ideal for any type of cultivation, both domestic and intensive, and particularly in green roof systems. A lightweight substrate can be created in situ by mixing the individual ingredients and adding a percentage of 20% to 40% Laterlite Agri expanded clay pebbles, or a substrate can be supplied pre-mixed ready for use. The characteristics of LaterliteGreen premixed lightweight substrate are optimised for use in green roof systems and roof gardens. It is consigned in big bags or can be pumped from a silo/tanker truck.
