The pebbles come in a resealable foil pouch and are baked at high temperature to create rigid, porous spheres that balance water holding and oxygen flow. Because they’re pH-neutral and chemically inert, they’re suitable for orchids, houseplants, hydroponic systems, and decorative top layers.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these clay pebbles improve drainage and root aeration?\u003c\/h3\u003e\n\u003cp\u003eThe porous surface and spherical shape create airy voids around roots so excess water drains away quickly while oxygen reaches root zones. That reduces the chance of root rot and encourages a healthier root architecture.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePorous structure increases oxygen exchange and prevents waterlogging.\u003c\/li\u003e\n  \u003cli\u003eRounded pebbles create air pockets for better root respiration.\u003c\/li\u003e\n  \u003cli\u003e4–16 mm size fits small to medium pots and hydroponic trays.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan LECA hold moisture and release nutrients for plants?\u003c\/h3\u003e\n\u003cp\u003eYes — internal pores absorb and slowly release water and dissolved nutrients, providing a buffer during brief dry spells.
