The key benefits of expanded clay

1. Optimal drainage

Expanded clay granules facilitate efficient drainage, thus avoiding the accumulation of stagnant water, a common cause of root rot. This substrate guarantees rapid evacuation of excess water while retaining the humidity necessary for plants.

2. Aeration of the roots

Thanks to its porous structure, expanded clay allows ideal oxygenation of the roots, essential for the healthy growth of plants, especially in controlled environments such as greenhouses or hydroponic systems.

3. Nutrient management

With a stabilized pH, this substrate offers simplified nutrient management, reducing the risk of imbalances that can compromise plant health.

4. Versatility of use

Suitable for a multitude of contexts, it can be used for:

• Hydroponics : Perfect support for recirculating or drip systems.
• Substrate Improvement : Mix with potting soil or soil to improve structure and porosity.
• Decorative mulch : Limits evaporation and prevents the proliferation of weeds.

5. Sustainability and ecology

Reusable after simple cleaning, this substrate helps reduce horticultural waste while offering an economical and ecological solution.

Recommended applications

Hydroponics

Expanded clay is particularly effective for hydroponic crops thanks to its ability to retain nutrients while ensuring optimal drainage. It can be used alone or in combination with other media.

Pot culture

Add a layer of clay granules to the bottom of the pots to improve drainage and prevent waterlogging. This is ideal for sensitive plants such as orchids or bonsai.

Improvement of substrates

Mix expanded clay with your soil or potting mix to increase aeration and reduce compaction. This promotes better rooting and improves nutrient uptake.

Decoration and mulching

Use the granules on the surface to protect the roots from temperature variations and reduce evaporation. This aesthetic mulch is suitable for both indoor plants and outdoor gardens.

Directions for use

1. Rinse before use : Before using for the first time, wash the pellets to remove dust and residue.
2. Balance pH : If using clay hydroponically, soak it in water adjusted to a pH of 5.5 to 6.5 to ensure optimal stability.
3. Adjust the amount : Use 10-20% expanded clay in your substrate mixes to improve porosity and drainage.
4. Reuse : After each growing cycle, clean the pellets to remove organic deposits and mineral salts.

Why choose 10L expanded clay?

1. Superior quality : Controlled manufacturing to ensure uniform particle size and consistent performance.
2. Versatility : Suitable for a wide range of crops and applications.
3. Plant growth support : Optimization of drainage, aeration and nutrient management.
4. Ecology and sustainability : Reduction of waste through reuse over several seasons.
