The PON Shop – Premium Soilless Substrate

Say goodbye to soggy soil and hello to thriving roots.
The PON Shop’s signature substrate is a hand-blended mix of pumice, black lava rock, and zeolite, designed for houseplant lovers who want cleaner, healthier, and lower-maintenance plant care. Our 4.5 liter bag is perfect for 3-4 houseplants. 

This soilless blend promotes strong root development, fast drainage, and excellent airflow — perfect for aroids, hoyas, orchids, and other tropical plants. Whether you're going full semi-hydro or just upgrading your potting mix, PON gives your plants the structure they need without the mess of traditional soil.
