Professors Clay Balls 50L – Premium Hydroponic Growing Media
Professors Clay Balls 50L are a premium hydroponic growing medium manufactured from 100% natural Lightweight Expanded Clay Aggregate (LECA). Featuring uniform 8–16mm clay pebbles, this versatile growing medium provides excellent drainage, root zone aeration and structural support for healthy plant development.
The lightweight, porous structure creates air spaces around plant roots while retaining a small amount of moisture. This helps maintain an effective balance between oxygen, water and nutrient availability, making Professors Hydro Clay an excellent choice for a wide range of hydroponic applications.
Excellent Drainage and Root Zone Aeration
Healthy roots require both moisture and oxygen to function efficiently. Professors Clay Balls provide an open, free-draining structure that allows excess nutrient solution to move through the growing medium without causing unnecessary waterlogging.
Their high porosity encourages oxygen availability around the root zone, supporting strong root development and efficient nutrient uptake.
Suitable for Multiple Growing Systems
Professors Clay Balls are suitable for numerous hydroponic and horticultural applications, including:
- Flood and drain hydroponic systems
- Deep Water Culture (DWC) net pots
- Drip irrigation and recirculating systems
- Aquaponics growing beds
- Indoor plant containers
- Mixing with coco or potting media to improve drainage
- Top dressing for indoor plants
pH-Neutral and Nutrient-Free
Unlike nutrient-enriched growing media, Professors Hydro Clay contains no added fertilisers. Its pH-neutral characteristics allow growers to manage nutrient concentrations and pH through their chosen feeding program.
Durable, Versatile and Easy to Use
Expanded clay pebbles are durable, lightweight and resistant to compaction. They can also be reused after thorough cleaning and appropriate sanitisation between growing cycles.
Always rinse the clay balls before use to remove loose dust and debris.
Whether you’re establishing a new hydroponic system or improving an existing setup, Professors Clay Balls 50L provide a reliable solution for drainage, aeration and root zone management.
