About Premium Semi-Hydro Soil Mix:

Introducing our Premium Semi-Hydro Soil Mix, a clean, soilless blend made for plant parents who want consistent hydration, better airflow, and fewer pests. This fine, root-friendly mix supports steady growth while giving you the low-maintenance benefits of semi-hydroponics.

Often called PON, this inorganic substrate keeps roots oxygenated and stable, helping prevent rot and encouraging strong, healthy growth. It’s especially loved for Hoyas, Alocasia, Anthurium, and other plants that thrive with a water-wicking, airy medium.

This mix is fully reusable and helps reduce overwatering by giving your plants access to moisture only when they need it. Use it with a water reservoir or a pot without drainage and enjoy a cleaner, easier plant care routine, perfect for anyone looking to transition into semi-hydro systems.

Try it out today with our 2L option, or stock up with our 4L option.
