BLACKSTONEPON is pre-fertilized and supplies plants with all essential nutrients for about 6 months, supporting healthy, vigorous growth. The purely mineral, 100% peat-free composition provides no breeding ground for gnats. In addition, BLACKSTONEPON remains structurally stable over time without clumping or compacting.
Thanks to its elegant dark appearance, BLACKSTONEPON can be used both as a complete plant substrate and as a premium decorative top layer. It is suitable for all types of houseplants and can be used in both conventional flower pots and LECHUZA planters with an irrigation system.

After about half a year, the fertilizer’s effect in the substrate begins to wear off, and it’s time to fertilize the plants again. With PERFECT LEAF slow-release and liquid fertilizers, houseplants are once again supplied with sufficient nutrients, allowing them to flourish with fresh, vibrant greenery.
To keep track of your plant’s water needs even in conventional flower pots, you can use the PON watering indicator. It reliably indicates when your plant needs to be watered in the mineral-based substrate.
DeclarationPlanting in LECHUZA planters
Step 1:
Place the irrigation layer—included with LECHUZA planters—on the divider in the planter. This is important to ensure that water is transported from the reservoir to the plant and to prevent waterlogging.
Then fill the planter with a thin layer of your chosen substrate, such as BASICPON—just enough so that your plant sits at the correct height in the planter.
Step 2:
Place the plant in your planter as usual. You don’t need to completely remove the soil from the roots.
Step 3:
Now you can fill the planter completely with the substrate of your choice, for example, using the PON funnel.
Step 4:
For the first 12 weeks, water your plant as usual from above, directly onto the substrate. Water only as much as the plant can absorb.
Make sure there is as little water as possible in the reservoir.
After this initial watering phase, you can water your plant through the water shaft. For planters without the LECHUZA irrigation system, continue to water the plant from above. You can find more information here.
