## Description

Indoor growers looking for a versatile growing medium can use these Legigo LECA clay pebbles in hydroponic setups, pots, terrariums, and more.

The natural clay pebbles measure 4–16 mm and come in a 15 lb size. Their porous structure supports airflow and drainage while retaining some moisture and nutrients.

Use them on their own or blend them with other growing media to adjust drainage and aeration for your planting setup.

## Worth noting

These round, lightweight pebbles are made from natural clay baked at high temperature. Their porous structure helps water drain while allowing air to circulate around roots, a useful combination for hydroponic growing and for pots where you want to improve soil aeration. The pores also retain some water and nutrients, which can gradually become available to the root system.

The 4–16 mm size range works for small to medium pots and garden plants. Use the pebbles as a growing medium, add them to potting mix, or place them at the surface or base of a pot. Their natural, rounded appearance also suits decorative arrangements such as succulent pots and terrariums.

Customer feedback highlights their usefulness across plant types and hydroponic setups, along with their appearance in pots and terrariums. Opinions on size consistency and dust vary. Rinsing and drying the pebbles between planting or repotting projects is a practical way to prepare them for reuse.

## How it fits

Choose LECA when you want a lightweight alternative to a soil-only approach or a material to mix into potting media for added airflow and drainage. For hydroponics, the pebbles can support plant roots while helping balance air and moisture around them. They’re also suited to orchids, succulents, indoor plants, aquaponics, and aquatic plant displays.

In a typical planting setup, you might use them as the main medium for a hydroponic plant, mix them into potting media, or spread a layer over the surface of a potted plant. The right approach depends on the arrangement: use them alone for a LECA-based setup, or combine them with other media when you want to change the texture and drainage of a mix.

## How to use it

Pour the pebbles into the chosen pot, hydroponic setup, or terrarium, then position the plant according to that setup. For soil-based planting, blend them with the existing growing medium or use them as a pot base or surface layer. Their rounded form makes them easy to pour and spread, while the lightweight material is convenient to handle when arranging plants or repotting.

For reuse, rinse and dry the pebbles between planting projects. The resealable foil pouch helps keep the unused material clean and dry during storage. When using them in an ornamental display, their natural round shape adds a tidy finish without taking focus away from the plants.
