Original expanded clay pebbles four liters

These expanded clay pebbles are a common growing medium used in various hydroponic and aquaponic setups. The four-liter bag provides enough material for several small pots or a single medium-sized reservoir. The pebbles are lightweight and porous, which helps maintain a balance of moisture and oxygen around plant roots for better health.

The round shape of the rocks ensures they do not compact over time, allowing for consistent drainage in the root zone. They are often used in ebb and flow systems or as a bottom layer in traditional pots to prevent root rot. This set of clay rocks is pH neutral and stable.

These listings highlight the utility of clay media for supporting plant structures without the weight of soil. The pebbles can be cleaned and reused across multiple growing seasons, making them a staple for indoor gardeners. They provide a stable environment for roots to anchor while facilitating easy nutrient delivery in water.
