Supplied in a 15-pound bag, the 4–16mm granules suit small-to-medium pots and many hydroponic or aquaponic setups. They’re inert, easy to rinse before use, and compatible with soil mixes or as a standalone substrate for soilless culture.\u003c\/p\u003e\n\n\u003ch3\u003eHow do Pulovin LECA pebbles improve drainage and prevent waterlogging?\u003c\/h3\u003e\n\n\u003cp\u003eLECA pebbles create air pockets and flow channels that help water drain quickly while leaving space for oxygen. This reduces standing moisture around roots, lowering the risk of oversaturation without relying solely on soil amendments.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e4–16mm size range allows fast drainage in small and medium pots.\u003c\/li\u003e\n  \u003cli\u003eRounded granules form voids for airflow and capillary action for even moisture.\u003c\/li\u003e\n  \u003cli\u003eInert fired clay won’t compact or break down like organic mulches.\u003c\/li\u003e\n  \u003cli\u003eIdeal as a bottom layer in container potting to speed runoff.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I use these clay balls for hydroponics, aquaponics, or orchids?\u003c\/h3\u003e\n\n\u003cp\u003eYes — Pulovin LECA works well across soilless systems and is commonly used for hydroponic and aquaponic applications.
