GROW!T® Horticultural Clay Pebbles are made from 100% natural clay and serve as a clean, pH-stable growing medium for hydroponic and soilless systems. They provide excellent aeration and drainage, helping maintain strong oxygen levels around the root zone while supporting beneficial bacterial growth for healthier plants. With strong structural integrity, these pebbles resist breaking and compaction, helping prevent dripper blockages in irrigation systems.
Pre-washed for stability, they can be used for hydroponics, aquaponics, drainage, aeration, or as a decorative top dressing. Pebble size ranges from 4 - 16 mm (0.16 - 0.63 in). For aeration in media, mix at a ratio of 4 parts clay to 7 parts soil to improve structure and root development.
