When you bring the term hydroponics into play, many people think of space technology because they have already heard it in this context. Still others who may have heard a little more about it think of "unnatural, artificial, not like in nature" etc.
More particularly, agriculture was already practised on floating rafts by the Aztec tribe of the "chinampas" about 1000 years ago because conventional earth cultivation areas were limited. Others believe that the Hanging Gardens of Babylon were the first hydroponic gardens. It doesn't really matter who first did what. The fact is that hydroponics works very well. Especially in the urban environment, when there are no "normal" cultivation areas, hydroponics has many advantages.
The term hydroponics derives from the Greek words for water (hydro) and work (ponos) - "working with water". In a hydroponic system plant roots do not grow in soil, but in nutrient-enriched water.
Compared to the cultivation in soil, the plants get everything they need to grow through the nutrient solution, delivered directly to the roots. Nutrients do not have to be dissolved out of the earth by pouring. This also saves the plant energy because it simply gets to the nutrients. All other things remain the same - the essentials are
Advantage of a hydroponic city garden is that you can grow everywhere, even if there is no soil or no soil can be used due to weight reasons.
DIY hydroponics plant cultivation. You will see, it is not rocket technology at all. With a summer like 2018 in Germany, always 30 - 40 °C, you will quickly learn to appreciate the advantages of hydroponics. With the nutrient storage container you have considerably less work compared to cultivation in soil. The larger the tank, the better the water supply. Even simple hydroponic systems can produce a great yield!
Since we are talking about the cultivation of vegetables and herbs in the private sector, we try to explain hydroponics in a simple and understandable way. Some experts will certainly have objections on how we explain, evaluate and classify things, but we want to show that everyone is able to cultivate hydroponics. Even those who do not have a degree in hydroponic plant cultivation. We also talk a lot about our own experiences, which are probably not entirely in line with scientific findings. We want to cultivate hydroponically, simply and profitably but without achieving the maximum yield, which is the case, for example, in commercial applications.
