Soils & Substrates 

  • Earth

    Earth is an organic growing medium and can be used anywhere without hesitation.

    There are several varieties of soil, which differ mainly in composition.

    Earth is especially useful for beginners in the Growing suitable.

  • Cocos

    Cocos consists of coconut fibers and has a rather fluffy consistency. Coconut mats are also available, which grow to many times their transport size through a buffer medium. Cocos is the most environmentally friendly hydromedium, has an EC value of zero and can be used more than once by treating it with special agents.

    Cocos contains a special fungus (Trichaderma) that protects plants from soil diseases.

    When growing on Cocos must be fertilized from the beginning.

  • Rock wool
    Rock wool

    Rockwool is very popular in cuttings production, as freshly cut cuttings can be planted in small prefabricated rockwool blocks. The EC value in this medium is zero and it provides a perfect water-air ratio, which ensures a good root climate.

    A disadvantage is the often not very environmentally friendly production.

  • Clay granules
    Clay granules

    Clay granules are especially suitable for professional cultivation in large plants because of their high efficiency and water-holding capacity.

    Attention should be paid to maintaining the correct pH and EC values, through the use of the right supplies.

To grow plants you need a medium and since there are other growing media besides soil, the question naturally arises:

Which medium is the right one for me?

As a beginner in Growing we recommend the well-tried medium soil, because it is more forgiving and does not necessarily require pH and EC meters. Organic media such as soil have a certain buffering function against supply errors and also contain many beneficial microorganisms and trace elements. In addition, the taste from hydroponics is often described as more "chemical".

Advanced growers or very ambitious beginners use hydroponics, but this requires mandatory measuring equipment and a lot of work and control. It is necessary to constantly check the pH and EC values. The advantage is, on the one hand, that the medium can be used more frequently and does not have to be disposed of as often as soil. Second, these media are sterile and do not carry the risk of contamination with germs or insect larvae.

The cost is about the same for both methods. The substrate in organic cultivation is slightly more expensive, but the equipment and maintenance in hydrological cultivation cause higher costs.

Combinations are possible, of course, in which different substrates are used depending on the growth phase, but this requires a high level of cultivation expertise.

A brief overview of the advantages of the different cultivation methods:

Soil Hydro
Buffer function against supply errors, as nutrients are released only slowly higher yields in a shorter time and more effective nutrient supply
numerous important micronutrients has high water holding capacity, good aeration and thus an optimal root climate
