LUWASA hydroponics

For good development plants need light, warmth, air, water, nutrients and a substrate, that offers support for their roots.
All factors have to be available in a balanced relation. Hydroponics improve in particular the micro-climate in the root area.

What is hydroponics?
Easy, clean, safe!

Instead of in the soil the plants root in expanded clay aggregate, a completely natural product made of clay.
The plants thereby profit from perfect growth conditions: Ideal balance of air, water and nutrients.
The stock of liquid nutrient solution in the planter assures a balanced supply.


Hydro Aufbau

Sophisticated construction

The complete technology combined in a decorative planter (1).
The cultivation pot (2) is put in a receptacle or cavity (6).

The nutrient solution (3), whose stock in the planter is readable from the water level indicator (4), nourishes the plants with water and nutrients. Expanded clay (5) offers the plant the required support.


Luwasa hydroponics in high vases

In high vases we recommend the use of soft inlays. These are available in nearly all common sizes. The hollow space in the lower part of the vase is filled with expanded clay (4) or polystyrene (3).

For very high planters it is recommendable to fill the bottom with expanded clay instead of polystyrene to avoid a potential top-heaviness of the planter and a related, possible instability.

The polystyrene below the soft inlay (2) serves also as a stable, flat base for the plant. (1) Water level indicator


Luwasa hydroponic system in large planters

This is how easy the planting with Luwasa hydroponics works:

1. Make sure that the cultivation pots (1) of all selected plants have the same height. When placing them in the planter (3), there should be 2cm remaining to the upper rim. TIP: If the planter is too high, a polystyrene inlay has to be placed below - what at the same time brings the positive side effect of a ground insulation.

2. Now place the cavity material (6) around the lower and side plants. This assures later a trouble-free replacement of particular plants.

3. The water level indicator (2) is still missing. Use a product with suction option, which has been particularly developed for large planters. (e.g. Topline).

4. If all plants are placed now correctly in the planter, it can be filled up with expanded clay (4). TIP: Hold therefore first the water level indicator and fix it with expanded clay.

5. Now you only need to fill the planter with water and fertiliser up to the optimum mark (OPT).
