Why these models

Neutral growing medium

The clay pebbles do not affect the pH of your water. This makes them a reliable choice for sensitive hydroponic setups.

Drainage and aeration

The round shape of the pebbles creates air pockets. This prevents soil compaction and helps roots breathe.

Moisture retention

The porous surface holds onto water while allowing excess to drain. This is helpful for orchids that need high humidity.

Indoor plant support

You can use these as a top dressing for succulents or mix them into soil. They help stabilize plants in hydroponic net pots.
