The DELTA Premium extends greenery horizontally in an elegant, slim and gently curved silhouette that fits where a conventional planter would feel too bulky. Its premium finish subtly reflects the light, while the elongated form showcases small arrangements, flowering plants and herbs on windowsills, sideboards, shelves and tables.

Original LECHUZA System · removable plant liner
The elongated form hides the entire self-watering system
Plant in the plant liner above the LECHUZA-PON layer. After the initial rooting period, the roots draw moisture from the integrated water reservoir, while the water-level indicator shows the available water level. The complete plant liner lifts out for easier plant replacement, care and root pruning.
The removable element is the inner plant liner, not the outer planter body.
The plant liner has the same color as the outer planter body for a unified premium appearance.
For the first few weeks water from above and afterwards use the reservoir with the MIN/MAX indicator.
The DELTA 10/20 does not have a drain plug and is recommended for indoor use.

01
Green in tight spots
The elongated footprint makes use of windowsills, sideboards, and shelves where a deeper round planter would not fit properly.
02
Planting is easy to change
The plant liner is removed together with the plant, making it easier for repotting, root care, and seasonal composition changes.
03
Premium look without unnecessary bulk
The slim curve and the high-gloss or metallic finish give a strong design presence without visually weighing down the surface.

The right start in four steps
The water reservoir is used after the roots move toward the moisture zone.
01 · Add the PON
Spread the provided LECHUZA-PON at the bottom of the plant liner as a watering layer.
02 · Complete the planting
Place the plant and fill with suitable substrate, leaving the filling shaft and the indicator free.
03 · Water from above
In the first weeks, water the substrate from above so that the roots grow toward the moisture zone.
04 · Switch to reservoir watering
When the plant starts to draw water, fill through the filling shaft and monitor the MIN and MAX indicators.
The identity of DELTA
A line that changes from every angle
The rounded edges and the smooth transition from the narrow base to the wide top give DELTA an almost sculptural character. It looks complete even with simple planting, without needing a large area around it.
Ideal for small arrangements
A plant or a horizontal composition
DELTA can accommodate a plant with spreading growth or a small composition of plants with similar light and water needs. For safe care, always choose species that require a similar watering schedule.
Where each size fits
10Narrow windowsill, shelf, small buffet, or table, for small plants and discreet arrangements.
20Deeper windowsill, kitchen counter, large console or table, for fuller horizontal planting.
How to choose the right setup
01First measure the available length and depth of the placement surface.
02Compare the root ball with the dimensions and depth of the inner plant liner.
03Choose plants that do not exceed about 20 cm when planted in the DELTA.
04For composition, combine only plants with similar light, water, and substrate requirements.

Frequently asked questions

It includes the DELTA Premium outer planter body, the removable plant liner in the same color, the authentic LECHUZA self-watering system with filling shaft and water-level indicator, as well as LECHUZA-PON for the base layer. The plant and additional substrate are not included.
What exactly is removable in DELTA Premium?
The complete inner plant liner holding the plant lifts out, while the outer planter body stays in place. This makes it easier to change the planting, care for or prune the roots and clean the planter.
Do I fill the reservoir immediately after planting?
For the first few weeks, water from above, until the roots reach the moisture zone. Then you can try the reservoir function: fill it about halfway and observe if the level drops in the following days. When the plant starts drawing water, use the filling shaft and the MAX indicator normally.
When do I refill the reservoir?
When the indicator reaches MIN, allow the appropriate dry phase for your plant and then fill up to MAX. Its duration depends on the species, light, and temperature, so monitor both the indicator and the condition of the substrate.
Can the DELTA Premium stay outdoors?
The DELTA Premium 10/20 does not have a drainage plug or an outlet for excess rainwater, and LECHUZA recommends it for indoor use. It should not be placed in an uncovered outdoor location where it can fill with rain.
How do I choose between DELTA 10 and DELTA 20?

The DELTA 10 has a plant liner of approximately 26 × 9 cm and a depth of 8.5 cm, while the DELTA 20 has a plant liner of approximately 34 × 12.5 cm and a depth of 12 cm.
