GROW!T 4–16 mm Clay Pebbles, 40 Liters

Build a well-aerated root zone with GROW!T horticultural clay pebbles. Made from 100% natural clay, this 40-liter bag provides a clean, pH- and EC-stable growing medium for hydroponics, aquaponics, potting mixes, and decorative top dressing.

Why growers use GROW!T clay pebbles

• 4–16 mm pebble size range
• Pre-washed and stable in pH and EC
• Free-draining structure helps oxygen reach roots
• Strong pebbles resist breaking and compacting
• Suitable for deep water culture, flood and drain, drip feed, and multi-pot systems
• Mix into coco or soil to improve aeration, or use as a top dressing

How to use

Rinse as needed before use and fully wet the pebbles so they settle in place. For a soil or coco blend, mix approximately 4 parts clay pebbles with 7 parts growing media, then adjust to your plants and system.

The 40-liter bag gives hydroponic growers plenty of lightweight, reusable media for a new setup, reservoir refresh, or larger root-zone project.
