Large Bag of Organic Leca Clay Pebbles

These natural clay pebbles are used as a growing medium in various hydroponic and aquaponic systems. The 16lb bag provides a significant amount of material for filling large pots or multiple smaller containers. Each pebble is fired at high temperatures to create a porous structure that holds moisture while allowing air to reach the roots.

The size of the pebbles ranges from 4mm to 16mm, offering a diverse texture that supports plant stability. This variety in size helps prevent the medium from compacting, which ensures that oxygen can circulate freely around the root zone. Proper aeration is a key factor in preventing root rot and promoting vigorous plant growth.

This set of clay balls is pH neutral and does not leach chemicals into the water or nutrient solution. They are durable enough to be cleaned and reused across multiple growing cycles, making them a sustainable choice for long-term gardening. These pebbles are also commonly used for drainage at the bottom of traditional soil pots.
