## Overview

These 2-liter bags of 8-15mm LECA clay balls are lightweight expanded clay pebbles made from 100% natural clay, thermally expanded to create a highly porous, stable medium. With 90% porosity and a density of approximately 230 kg/m³, they provide excellent aeration and drainage for hydroponic, aquaponic, and indoor gardening systems. Resistant to pH and EC fluctuations, they support healthy root zones and beneficial bacteria growth, making them a must-have for professional and hobbyist growers alike.

## Description

Clay pebbles also known as LECA (Lightweight Expanded Clay Aggregate), Hydrotons, or expanded clay are lightweight, porous, semi-rounded pellets made from 100% natural clay. These are thermally expanded at high temperatures (appx. 1200°C), which causes the clay to "pop" like popcorn, forming a structure full of micro and macro-pores.Expanded clay pebbles or LECA resemble oddly shaped, semi-rounded pieces of clay-colored popcorn. The high-heat popping during the manufacturing process gives the medium its large, airy macro-pores (spaces between each piece of expanded clay), in addition to its micro-pores, which are contained within each piece of expanded clay.Horticultural clay pebbles are clean, pH stable, and offer great aeration and drainage in hydroponics, especially in flood and drain, deep water culture, and drip feed systems. Due to their unique structure and ability to cover a large surface area, they offer the ideal environment to foster beneficial bacterial growth around the root zone, leading to naturally healthier plants.Drain freely and do not hold any excess water, providing good oxygen levels around the root; suitable for flood and drain systems, multi-pot and drip feed systems.8–15 mm - Regular Grade ClayballsAppearance : Medium-sized, semi-rounded pebbles.Best Uses:General hydroponic systems : DWC, flood & drain, drip systems.Kratky method : Keeps base stable while allowing air gaps.Aquaponics grow beds : Excellent drainage and bacteria habitat.Indoor decorative planters : Combines aesthetics with utility.Advantages:Balanced water retention and air space.Provides anchorage for most hydroponic vegetables.Doesn't compress or decompose over time.Netpot Compatibility:2-inch netpots - Usable, Suitable as a top covering or bottom filling.3-inch netpots - Perfect fit.5-inch netpots - Suitable as a mid-layer or with mix.
