Clean, mineral, and perfectly suited to the minimalist aesthetic of cacti. The LECHUZA CACTUSPON forms a fine-grained yet open gray–charcoal base, highlights the plant, supports even tall forms, and creates a stable root environment with abundant air and quick water removal.
The 3 L package indicates the volume of the material, not the coverage area. The required amount depends on the internal volume of the plant liner and the root ball.
The fine-grained composition of pumice, lava, zeolite, and activated carbon creates many stable gaps between the grains. Water drains away without forming a heavy, muddy mass, while the root remains in a porous environment that does not compress over time.
The special fine-grained composition has increased drainage capacity and limits the formation of permanently saturated zones around the roots.
The grains do not compress and do not become muddy, so the structure remains permeable to air even after long-term use.
The stable volume keeps the plant upright and provides a secure base for tall cacti, without the settling common in organic substrates.
CACTUSPON can be used throughout the entire planter. What changes is whether the planter has a LECHUZA system or simple drainage holes.
Fill the entire plant liner with CACTUSPON and use it as a complete replacement for regular soil for cacti and succulents.
On the separation base, first place the LECHUZA-PON that comes with the planter. Then add CACTUSPON at planting height and around the root ball.
Use a planter with unobstructed drainage holes. The water must completely drain, and the next watering should follow the needs of the species and the season.
The goal is to stabilize the root ball without unnecessary injuries and to keep the drainage pathways open.
In a common planter, make sure the holes are free. In LECHUZA, first place the PON supplied with the system on the separation base.
Add a thin layer of CACTUSPON, enough so that the base of the plant reaches the correct height without burying its neck.
Remove only the very loose old substrate. The official instruction does not require a complete cleaning of the root ball before filling around it.
In a LECHUZA system, water only from the top for the first 12 weeks. In a regular planter, always water from the top, allowing the water to drain completely.
CACTUSPON is not pre-fertilized. This way, nutrition can be adjusted to the specific species, season, and development stage, without automatically adding an initial dose. Use suitable fertilizer for cacti and succulents following the product's dosage instructions.
The purely mineral substrate does not provide the usual moist organic soil where mold and gnats thrive. This reduces the favorable conditions, but does not treat infestations that already exist on the plant, in the roots, or in organic debris.
Both are mineral and volume-stable, but they are not the same product. The essential difference lies in the type of plant, the fine-grained structure, and the initial fertilization.
| Main use | CACTUSPON: Especially for all cacti and succulents. | LECHUZA-PON: Universal option for indoor plants. |
|---|---|---|
| Composition | CACTUSPON: lightweight pumice, lava, fine-grained zeolite, and plant charcoal. | LECHUZA-PON: Washed pumice, lava, zeolite, and slow-release fertilizer. |
| Granulation | CACTUSPON: particularly fine-grained for increased drainage action. | LECHUZA-PON: general-purpose mineral structure for air and water balance. |
| Initial fertilization | CACTUSPON: without added fertilizer, for nutrition according to needs. | LECHUZA-PON: Pre-fertilized with PERFECT LEAF for 6–8 months. |
There is no exact match based solely on the diameter of the planter. The height, shape, and volume of the root ball change the amount required.
For a small repotting, a top-up, or several very small planters, depending on the actual internal volume.
For a larger plant liner or several small repottings, without changing the composition or usage method.
See the CACTUSPON 6 LPractical calculation: Required liters of CACTUSPON ≈ internal volume of the plant liner − volume of the root ball. If the LECHUZA system already includes PON for the base, also subtract that volume.
CACTUSPON is the specialized choice for cacti and succulents. For other groups of plants, LECHUZA offers compositions with different structure and nutrition.
Purely mineral universal substrate for indoor plants, pre-fertilized with PERFECT LEAF for 6–8 months.

See the BLACKSTONEPONCarefully remove roots and organic residues, rinse the material well, and let it dry before reuse. Substrate from a sick plant should not be reused without proper disinfection.
The composition is based on natural raw materials. Slight deviations in shade, shape, and grain distribution do not change the purpose or function of the product.
In a regular planter, free drainage holes are needed, and watering only when required by the species, the season, and the drying of the substrate. In a LECHUZA system, after the rooting phase, wait until the indicator reaches MIN: the official guideline recommends a dry phase of at least two weeks for cacti and, depending on the conditions, even longer.
It is a purely mineral, fine-grained substrate specifically for all cacti and succulents. It contains pumice, lava, fine-grained zeolite, and plant charcoal. It is 100% peat-free and volume-stable.
No. CACTUSPON is not pre-fertilized, so nutrition should be adjusted according to the type, season, and growth stage. Use appropriate fertilizer for cacti and succulents according to the product dosage.
Yes. You can use 100% CACTUSPON throughout the entire plant liner. In a LECHUZA planter, first place the LECHUZA-PON that accompanies the system on top of the separation base and then add the CACTUSPON.
No. Gently remove only the very loose substrate without damaging the roots. The official guideline states that the root ball does not need to be completely cleaned before the plant is placed and the new substrate is added.
Always water from above and let the water drain completely through the holes. The next watering is done when the substrate has dried to the degree required by the specific species, taking into account the season, temperature, and location.
For the first 12 weeks, water only from the top and keep as little water as possible in the water reservoir. After rooting, use the filling shaft. When the indicator reaches MIN, maintain a dry phase of at least two weeks for cacti and longer when required by the species and conditions.
CACTUSPON is specially designed for cacti and succulents; it is particularly fine-grained for increased drainage, contains plant charcoal, and does not have initial fertilizer. LECHUZA-PON is a universal substrate for indoor plants and is pre-fertilized for 6–8 months.
