Growing Soil Mixtures
You can find special growing soil and soil-based substrate mixtures for successful cultivation here. The composition is tailored to the plants, pre-fertilised or not, depending on your preferences.
Mix your own soil mixtures from individual components
One advantage of soil as a growing medium is that its composition can be adapted to a wide variety of plants and growing situations. A soil mixture for indoor growing can, for example, achieve a better air supply for the plant by adding perlite or ensure a higher water absorption capacity with the help of coconut fibre substrate. Guano or worm humus are also popular organic components of self-mixed grow soil, which act as long-term organic fertilisers.
Cultivation on soil enables long-term fertilisation
In general, slow-release organic fertilisers can only be used on soil, as they are dependent on the soil flora and the composition of the medium to develop their effect. Long-term fertilisation is not possible in a nutrient solution and the risk of over-fertilisation is therefore much greater. At the same time, it is possible to utilise the microorganisms living in the soil, i.e. bacteria and fungi, to the benefit of the plants, as they convert dead biomass into nutrients.
Is grow soil reusable?
After a successful grow, the soil has been depleted by watering, fertilising, buffering and the removal of nutrients from the plants and should not be reused for growing the same plants or edible crops in general. However, it does not have to be disposed of, but can be used for less demanding houseplants and ornamental plants that have different nutritional requirements.
