Made from fossilised diatoms and heat treated for strength, Calcined Diatomaceous Earth Mini Pebbles 2–10mm are a lightweight soil amendment and growing medium. 

Their porous structure supports root health, balances water retention, and improves soil performance in indoor, outdoor, and hydroponic gardening.

They enhance root development by preventing compaction, improving aeration, and creating consistent moisture levels. Whether used in lawns, houseplants, or hydroponic systems, these pebbles provide long term soil support.
