What sets them apart
Hydroponic support
These pebbles are for growers using flood and drain or deep water culture systems. They hold the plant in place without breaking down over time.
Moisture management
The expanded clay structure absorbs water and releases it slowly to the roots. This helps prevent both drying out and over-saturation.
Reusable media
These rocks are durable and can be cleaned for use in multiple growing cycles. They do not compact like traditional soil.
Neutral pH balance
The clay pebbles are chemically inert, meaning they will not change the nutrient balance of your water. This gives you total control over plant feeding.
