Expanded clay guide

The all-rounder for home and garden

Expanded clay became well known only when hydroponic culture was booming. The beginnings were already in 1967, the breakthrough, however, took place only about 1973/74. Hydroculture means that plants are no longer in the earthgrow, but in water enriched with special nutrient solutions. So that the roots have a firm hold, until today expanded clay used. In 1974, the first hydroponics business was opened worldwide. Ms. Lucie Mohr from Munich discovered the market gap for herself and the business mutated into an Eldorado for lovers of this special plant breeding. expanded clay became known and loved.

After several attempts with different materials, both suppliers and customers realized that only expanded clay brings optimal properties for plants. The small globules are light, have the optimal surface tension and are very plant friendly. That’s because that expanded clay Made of natural material, the sound is made. In construction, it serves as an aggregate for the production of concrete or mortar. Since it has optimum thermal insulation values, it is often used as an insulation material under the screed for renovations and new buildings. Also, a bed as a cold bridge to the attic is a frequent use.

From nature, for nature

In horticulture offers expanded clay the optimum of its properties. It is still considered the perfect foundation for hydroponics. It encloses the root without burdening it. In it, indicators for the water level can be easily inserted and even large plants can be transported without much effort. But it is not only there that Bläthton scores points. Even large conifers or deciduous trees can be cultivated in pots thanks to expanded clay. It then serves as the basis for sufficient water extraction or to loosen the potting soil, No plant likes waterlogging and the first layer of a pot has to work like a drainage. This means that both during cloudbursts as well as too much irrigation water, the unused liquid flows away. Since expanded clay is offered in different diameters, thicker spheres should be used here. And not only the water drainage plays a role here. Ants like to build their nests in flowerpots. They enter through the vent hole and cause great damage. Who fills the bottom of the vessels with expanded clay bypasses the endangerment almost completely.

In addition to the drainage, without which the roots begin to rot, ventilation is also important. Here, small diameter expanded clay is mixed with the potting soil. This has two advantages. The clay absorbs water and, to a certain extent, can deliver it to the plant in small portions. The risk of over-pouring is eliminated. The second advantage is that the earth can not compress and even the smallest hair roots can breathe. When greening the roofs of garages and garden huts, expanded clay is the first choice. This is primarily due to its low weight. Even wooden roofs are able to withstand it and the property of storing water makes it the ideal base for Sempervives, grass and other small plants.

That’s what consumers should be aware of

An important differentiator is that expanded clay is by no means intended for the cultivation of plants for the construction industry. It has been coated and may contain substances that damage the plants. Before buying it is important that both the type of production and the composition of the material is questioned. This should be noted for every type of use. Be it that the screed in the nursery receives an insulating layer of expanded clay or the floor of the garden with the material should be permanently loosened. In Germany, clay pits are only available to a limited extent and most of the offers come from Austria or the Czech Republic.
