HYDRO CLAY PEBBLES 2.5L

Expanded Clay Pellets

Brunnings Hydro Clay Pebbles are lightweight expanded clay pellets created by baking and tumbling natural clay at high temperatures. This process creates millions of tiny air pockets, producing a highly porous growing medium with excellent aeration and drainage properties.

With a neutral pH and excellent moisture-holding ability, Hydro Clay Pebbles are ideal for hydroponics, aquaponics, semi-hydro growing, and improving the health of potted plants.

🌱 Why Use Hydro Clay Pebbles?

✔ Lightweight and highly porous
✔ Excellent drainage and airflow
✔ Neutral pH for stable growing conditions
✔ Will not rot or break down
✔ Absorbs and releases moisture efficiently
✔ Helps reduce the risk of indoor pests such as fungus gnats
✔ Reusable and long-lasting

🪴 Versatile Uses

Hydro Clay Pebbles can be used as:

• A hydroponic growing medium
• A decorative top dressing for indoor plants
• A drainage layer in pots and containers
• A soil amendment to improve aeration and drainage

Their porous structure helps support healthy root systems by preventing compaction and increasing oxygen around the roots.

💧 How to Prepare Hydro Clay Pebbles

Before first use:

1. Rinse thoroughly to remove any dust or fine particles.
2. Soak the pebbles for 6–8 hours to fully saturate their micro-pores.
3. Drain and use as required.

Pre-soaking allows the pebbles to retain moisture more effectively and makes water more readily available to plant roots.

🌿 Use as an Indoor Plant Mulch

Hydro Clay Pebbles make an attractive and functional top dressing.

Benefits include:

✔ Decorative finish for pots
✔ Helps retain moisture
✔ Reduces soil drying
✔ Increases humidity around plants
✔ Helps reduce fungus gnat activity

🌱 Improve Drainage in Pots

For improved drainage:

• Add a 4cm layer of pebbles to the bottom of pots before adding potting mix.

Alternatively:

• Mix at approximately 1 part Hydro Clay Pebbles to 5 parts potting mix to improve airflow and reduce waterlogging.

💧 Hydroponic Growing Medium

Hydro Clay Pebbles can be used as a standalone growing medium and are ideal for plants that enjoy excellent aeration and do not rely heavily on soil nutrients.

Suitable plants include:

• Orchids
• Hoyas
• Monsteras
• Philodendrons
• Pothos
• Pileas
• Most succulents
