For some reason, it’s stubbornly to believe that it’s possible to follow the BP. It will be destroyed and there will be few competitors. Honestly speaking, it’s quite a matter of how it’s been removed from the biosphere exclusively. Much more likely is a scenario in which everyone will suffer.
It is not clear that there is no need for it. Fortunately, there is a way out. It is one of the most important factors in the emergence of culture, science and art. And in our case, it will be agriculture that will become the guarantor of survival. But, of course, with some plants, unlike plants, unlike mushrooms, are not too comfortable in closed underground rooms. Therefore, hydroponics.
It is not new. It turned out only recently. Very essence hydroponics It is a simple solution for nutrient needs. Or it plays an exclusively supporting function. But what can we say, hydroponic system.
Of course, it’s not a bad thing. But if you’re doing everything right, then you can organize a good housekeeping. The main thing is to know how to do it correctly. But enough common words, let’s move on to the specifics.
Let’s start with the main methods. hydroponics, their pros and cons.
It will keep you on the surface. The roots of the plant are completely immersed in water, and the stem clings to the retainer. For cranberries, for example. It is not possible to regulate water flow.
The roots of the plant are partially immersed in water, which is slowly circulating through a special electric pump. If the structure is positioned automatically, then the water flow will also be automatic. Slow down, saturating the roots of plants with beneficial substances. 1-2 cm thickness of water should be approached 1-2 cm. It can lead to the development of stagnation. In addition, this method hydroponics poorly suited for most vegetable crops.
Substrate culture. Basic
It implies the use of the substrate (expanded clay, gravel, sand). It is needed to ensure that it is necessary to provide the plant. In this case, aeration is carried out automatically, since it will remain all the same. It is a matter of course (1-2 cm) that it is necessary to invert it. This method is also called “pot culture”. So you can grow vegetables. It’s not a problem, since it’s not a problem.
A variation of this method hydroponics It is a “wick system”. It is not necessary to follow the rule of thumb for small plants. But it is a potting culture.
Substrate culture. Drip
It is due to the special adjusting droppers. It is possible electronic, it is possible. The main thing is to be able to regulate. This allows you to control the moisture content and saturation of the substrate. It doesn’t create excessive moisture. This is why this method is often used in industrial. hydroponics.
Substrate culture. Periodic flooding
Most popular method hydroponics, however, it is highly dependent on agricultural and agricultural engineering skills. The plant can be in two phases. It is necessary to ensure moisture. For 15 minutes is the case with water with beneficial substances. Depending on the type of plant. This can not be done without electricity.
In the future we will try to focus on those methods. hydroponics, which are the least costly in terms of attracting additional resources, especially electricity. That is, on the “pot”, “wick” and “drip” substrate. It is also a culture that it is best suited. If you are on the next pages.
