What is the best hydroponics system for clay pebbles?
Flood and drain or a dripper system will deliver the fast growth rates and yields using clay pebbles.
Clay Pebbles can be used for:
- Aeration of growing media - ideal to mix into coco coir or soil to aid aeration
- Drainage - will hold water as well as offering great aeration properties and free draining
- Decoration - looks great as a top dressing for pots and also helps to prevent evaporation
- Hydroponics/hydroculture - used widely in hydroponic growing, they are ideal for flood and drain, deep water culture and drip feed systems
- Aquaponics - are also ideal to be used in aquaponic systems
When used in aeration of growing media, mix horticultural clay pebbles into your coco coir or soil at a rate 4 parts clay to 7 parts soil to loosen up the structure, leading to better root development.
