Their rounded shape leaves open air spaces around roots, while the porous interior holds a small buffer of moisture, helping balance oxygen and water more effectively than dense soil alone. Because they are pH-stable and slow to break down, they suit long-term use in passive hydro, reservoir-based growing, top-dressing, or for opening up heavier substrates that stay wet too long. Rinsed and reused correctly, they offer a low-mess way to improve drainage, reduce compaction, and keep root zones cleaner, airier, and easier to manage during routine watering and repotting in indoor setups.\u003c\/p\u003e","brand":"Nieuwkoop","offers":[{"title":"1l","offer_id":61193361490250,"sku":"MM-MEC-0263","price":6.25,"currency_code":"EUR","in_stock":true},{"title":"3l","offer_id":61193368731978,"sku":"MM-MEC-0535","price":10.25,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0979\/5115\/4506\/files\/0906d2_2db46c85c3424b75a54f33310ac8a876_mv2.webp?v=1772578584","url":"https:\/\/foliage-factory.live\/products\/expanded-clay-pebbles-8-16mm","provider":"Foliage Factory","version":"1.0","type":"link"}
