Monk Pon - Triple-Washed Semi Hydroponic Plant Substrate

Monk Pon is triple-washed before packaging, so most of the prep is already done. Before planting, give it one quick rinse in a draining inner pot or sieve to remove any fine dust or debris created during shipping. Allow the rinse water to drain away before filling your reservoir.

Monk Pon is a completely inorganic blend of pumice, lava rock, and zeolite, with no added fertilizer—giving you control over your plant’s feeding routine.

Use a complete fertilizer formulated for hydroponic growing, following its dilution and feeding instructions for your plant and setup. For regular feeding, use the manufacturer’s recommended maintenance strength rather than guessing a dose. Hydroponic plants need nutrients supplied through their nutrient solution.

Use enough Monk Pon to surround the roots and hold your plant securely upright. Gently settle the granules around the roots without tightly packing them, and avoid burying the plant’s crown or stem deeper than its appropriate planting level.

The amount depends on the inner planting pot’s volume and the size of the root system. For self-watering planters, measure the planting compartment—not the outer water reservoir. View the size guide.

Monk Pon is suitable for Monk self-watering planters and other setups designed for mineral substrates, including many wick-fed and reservoir-based semi-hydro systems.

Compatibility depends on the planter’s design: the wick or substrate must provide a reliable path for moisture to reach the roots. Follow your planter’s instructions for substrate compatibility and water level; some self-watering pots are designed specifically for soil-based mixes.

Another substrate may suit you better if you prefer a traditional potting mix with fertilizer already included, your planter requires a specific growing medium, or you’re starting tiny seeds that need a finer medium.

Monk Pon is a good fit for growers who want a mineral substrate and control over their nutrient routine. The best choice depends on the plant, watering system, and care preferences.

Yes. Its durable mineral ingredients make Monk Pon reusable with proper cleaning. Remove old roots and debris, rinse thoroughly, and sanitize appropriately before using it for another plant. Reusing growing media requires attention to cleanliness to avoid carrying over pests or pathogens.
