Soil

Fertiliser for growing in soil. Soil is still by far the most popular growing medium with a correspondingly large selection of suitable fertilisers and tonics. Depending on the grow soil used - whether pre-fertilised or low in nutrients - you can wait a little longer to apply fertiliser when growing in soil than with other media. If very large pots and nutrient-rich potting soil are used for cultivation, it is often sufficient to add the fertiliser in the flowering phase.

Organic or mineral grow fertiliser for soil?

Organic fertilisers for soil must be added with a certain time buffer in advance, as the nutrients are not immediately available to the plants in the soil, but must first be dissolved by microorganisms in the potting soil. These microorganisms are also the reason why organic fertilisers are actually only available for soil - they do not exist in sterile media or in water, or not in sufficient quantities. In this respect, watering organic soil fertilisers is also an important element in stabilising the soil fauna.

Due to their immediate effect, mineral fertilisers are a good choice for indoor growing, which has shorter vegetation cycles than outdoor cultivation. However, the concentration should be lower than with organic fertilisers, otherwise there is a risk of over-fertilisation. Instead of a long-term planned fertilisation strategy, mineral fertilisers on soil make it possible to counteract deficiency symptoms selectively and only fertilise according to schedule and need.
