Fertilisers and nutrients
The newer NPK (nitrogen, phosphorus and potassium) plant fertilisers from the high-tech laboratories are absolutely harmless from a biological point of view and also have an impressive fertilising effect. With specially coordinated fertilisers and nutrients, almost nothing can go wrong when growing.Fertilisers & nutrients for indoor growing
Fertilisers and nutrients are an important tool, especially in indoor growing, and their use is recommended for many plants. The desire to make effective use of the limited space alone means that you cannot give every plant a huge pot that provides potting soil and nutrients for the entire life of the plant. Constant repotting is also time-consuming. It is therefore a sensible measure to top up the existing soil with fertiliser if it can no longer provide the plant with enough nutrients. And with inert media such as coconut fibre or hydroponics, it is only possible to regulate growth using fertilisers anyway.
Fertilisers can not only be used to control the general development of the plant during indoor growing, but also to intervene specifically in certain phases of development and promote certain attributes. The use of organic fertilisers guarantees a clear conscience.Nitrogen, phosphorus and potassium fertilisers
...also known as NPK fertilisers for short (the N stands for the chemical abbreviation for nitrogen), form the basis for an ideal supply of nutrients in plant cultivation. However, it is important to ensure that the exact composition of these three basic substances is suitable for the respective application and the needs of the plant. Too high a concentration of one or more ingredients can quickly have a detrimental effect on the breeding result. Signs that the plant is deficient in certain nutrients should therefore be taken into account. In addition to N, P and K, many fertilisers also contain other ingredients such as vitamins or iron (Fe), which also have specific effects on the growth and flowering of plants.Beware of over-fertilisation
According to the motto 'a lot helps a lot', many growers have already fertilised their crops to death. Fertiliser manufacturers therefore include precise tables with their fertilisers that show the best phase for mixing a certain fertiliser in a certain quantity. Although these are generally only more or less rough guide values, they at least indicate the direction. Any signs of deficiencies in the plants, the substrate (possibly already pre-fertilised) and any extra nutrients added should always be taken into account. Over-fertilisation often has the same effect as a nutrient deficiency and nobody likes to see dead plants.
