## Description

Porous, lightweight expanded clay pebbles help create an airy root zone while holding some moisture, making them useful for semi-hydroponic growing and everyday potting. The mixed 4–16 mm size can settle around roots and also works as a drainage layer or a soil amendment.

Choose them for a soilless setup when you want a loose growing medium, or mix them into potting soil when your priority is improving drainage. Their reusable design makes them practical for recurring plant projects.

## Technical details
- Product: LECA expanded clay pebbles
- Quantity: 6 lb
- Size: 4–16 mm
- Volume: 6 liters
- Properties: Porous, lightweight, inert, and pH-neutral
- Reuse: Can be cleaned and reused

## Requirements
Rinse the pebbles thoroughly before first use to remove fine shipping dust. For semi-hydroponic growing, the product guidance recommends soaking them for 24–48 hours before planting. Clean the pebbles regularly as part of your plant-care routine.

LECA is a growing medium, not a source of plant nutrients. For semi-hydroponic setups, provide nutrients through a hydroponic nutrient solution or liquid fertilizer. When moving a plant from soil, wash soil from the roots and manage the transition as part of the repotting process.

## Everyday use
For semi-hydroponics, the pebbles provide support around roots while their porous structure helps maintain airflow and moisture. They are also suited to orchids, succulents, bonsai, and other potted plants. To use them with conventional potting soil, mix them in to improve permeability, place them at the bottom of a container as a drainage layer, or spread them on top as a decorative covering that can reduce water evaporation.

For example, an orchid grower can use the pebbles as a semi-hydro medium, while someone keeping plants in potting mix can add them to a container for a more open mix. That flexibility makes this a useful choice when you want one growing material for different planting methods rather than a medium dedicated to a single setup.

Customer feedback is positive about use with houseplants and hydroponics, including orchids. Opinions vary on the pebble sizes and how much rinsing they need, so rinse until the water runs clear before planting.

## Questions before you buy
**Can I use these for orchids?** Yes. Their mixed 4–16 mm sizes are described for orchid growing, including semi-hydroponic setups, where the pebbles provide root support and an airy, moisture-holding medium.

**Can I add them to potting soil?** Yes. Mix them into soil to improve permeability, use them as a layer at the bottom of a pot, or apply them as a top dressing.

**Do the pebbles provide plant nutrients?** No. LECA is a growing medium rather than a nutrient source. For semi-hydroponic growing, use a hydroponic nutrient solution or liquid fertilizer to feed the plants.

## Final verdict
Halatool’s 6 lb bag offers a versatile supply of reusable clay pebbles for growers working with semi-hydroponics, orchids, and potted plants. Choose it when you want a lightweight medium that supports airflow and moisture management, or a practical addition to soil for drainage and permeability.
