Function & Structure
1. Function & Structure
The Principle – Rethinking Irrigation
tontau is based on a proven, centuries-old method:
A vessel made of low-fired clay is filled with water. Its porous structure allows water to be released slowly and evenly. Embedded in the soil, tontau provides surrounding plants with just the right amount of water – naturally and efficiently.
Advantages of the Method
- Simple & electricity-free: No technology, no electricity, no effort.
- Water-saving: Reduces water consumption by up to 70%.
- Plant-friendly: Automatically adapts to the water needs of plants.
- Weed-suppressing: Water reaches only the plant roots, keeping the surface dry.
The Challenge of Traditional Clay Pots
Traditional clay pots have weaknesses:
- Require frequent refilling.
- Fragile and prone to breaking.
The Solution: tontau
tontau perfects this technique:
Robust, efficient, and easy to use – without losing the benefits of the traditional method. Sustainable irrigation has never been this simple.
2. Water Distribution – How Soil Affects Your Irrigation
The efficiency of your tontau largely depends on the soil. Depending on the type of soil, water spreads differently in width and depth. To ensure even irrigation, we recommend calculating with a watering radius of 30 cm. This way, your plants receive optimal hydration—regardless of minor soil differences.
How Water Distributes in Soil
- Sandy Soil: Water drains quickly into the depth, minimal lateral distribution (approx. 20 cm radius).
- Sandy Loam Soil: Retains water better, distribution up to approx. 30 cm radius.
- Sandy Clay Loam Soil: Optimal water retention, widest distribution up to 45 cm radius.
3. tontau – Rethinking Irrigation
tontau optimizes traditional irrigation: Strengths remain, weaknesses disappear. The result? A sustainable, efficient, and flexible system, perfectly tailored to your needs. Here’s what makes tontau better:
A. Perfect Water Permeability
The specially fired clay ensures ideal water release:
- Needs-based supply – Your plants receive exactly the amount of water they need, even on hot days.
- Efficient water flow – No clogging, no waterlogging – tontau distributes water evenly.
B. Durable & Long-Lasting
tontau is more robust than traditional clay pots:
- Thoughtful shape & material thickness – Resists mechanical stress in the garden.
- Built to last – Designed for continuous use, even in challenging conditions.
C. Continuous Water Supply
tontau doesn’t need constant refilling:
- Flexible connection – Works with any water reservoir or rain barrel (1/2" or 3/4" hose).
- Worry-free irrigation – Automatic, demand-driven water supply without manual refilling.
D. Larger Surface for Maximum Efficiency
The grooved structure of tontau makes all the difference:
- Faster water absorption – Increased contact surface for even water distribution.
- Effective in any soil – Even in denser soils, tontau prevents waterlogging and ensures optimal hydration.
E. Easy Installation – Plug & Play
tontau can be installed in just a few steps, no experience needed:
- Connect the hose, place tontaus – done!
- Includes accessories: Hose, T-pieces, hose clamps – everything you need.
F. Sustainably Designed
tontau saves water and relies on eco-friendly materials:
- Resource-efficient clay – Low-fired to reduce environmental impact.
- Up to 70% water savings – Thanks to targeted irrigation directly at the roots
