The same 8-15mm size specification used by professional growers worldwide. Works equally well for orchids, monstera, pothos, snake plants, and bonsai.\u003c\/li\u003e\n\u003cli\u003eHEALTHIER ROOTS, NO MORE ROOT ROT — The porous structure delivers ample oxygen to root zones while wicking moisture upward through capillary action. The textured surface area also fosters beneficial bacterial colonies that promote naturally healthier plants. No more soggy soil. No more guessing at watering schedules.\u003c\/li\u003e\n\u003cli\u003epH NEUTRAL, LOW EC, EC STABLE — Inert and chemically stable, so your nutrient mix stays exactly where you set it. Kiln-fired at high temperature, GrowPeb pebbles won't break down, decay, or leach minerals into your reservoir. Rinse before first use to remove fine clay dust — standard practice for all premium LECA — then enjoy years of reuse, season after season.\u003c\/li\u003e\n\u003cli\u003eCONSISTENT 8-15MM SIZING — UNLIKE WIDE-RANGE COMPETITORS — Many clay pebbles use a 4-16mm range, which means dust, fragments that fall through net pots, and chunks that create air pockets. GrowPeb's tighter 8-15mm range matches the specifications used by leading horticultural brands — predictable wicking, even drainage, no clogging.\u003c\/li\u003e\n\u003cli\u003eCRAFTED IN INDIA, BUILT FOR YOUR GROW — Made from natural Indian clay using high-temperature kiln firing — the same sourcing region trusted by 100-year-old American gardening brands.
