Hydroponics at home is a way of growing a plant without soil in a solution of water, from which they take all the necessary nutrients for life as well as from the soil.
This method is nothing new. A similar method was used even in ancient times. As an example, one of the 7 wonders of the world - the Babylonian Hanging Gardens of Babylon was an attempt to introduce this technology into reality. In the thirties, attempts were also made to grow plants in water by our and American scientists.
In the process of research, we came to the fact that for the correct execution of the process, the presence of a certain base is necessary, which must be in solution and nutrients must move along it like through capillaries.
Let's take a closer look at this process. A plant can grow in liquid, but for its existence it needs certain conditions, that is, the presence of nutrients. A plant in a liquid is capable of absorbing these elements and oxygen, but for this there must be something to help move them along the stem.
The main purpose of hydroponics is landless cultivation, which stimulates plant growth by stabilizing the volume of liquid containing oxygen and mineral salts.
At the moment when the growth of the root system slows down in a moving fluid, they occur fast absorption of nutrients and oxygen. Moreover, one must bear in mind the fact that both an insufficient amount of oxygen and its oversaturation are dangerous here. And the main task of the gardener is to select the ideal proportion of all elements, i.e. water, nutrients and oxygen, which meets the needs of a particular culture.
This is a prerequisite for the highest quality harvest.
Note: A hydroponic solution is a liquid containing nutrients.
Ready-made solutions are on sale with strict adherence to all proportions for a particular plant.
Here one must not forget about the humidity indicator, the temperature of the liquid and the environment, the presence of ventilation, lighting, as well as the genetic characteristics of the plant itself.
What kind of plants can grow in water:
It is quite possible to grow garden crops, flowers, seedlings for subsequent planting in the ground, using hydroponics, even on the windowsill.
Many agronomists use this technique, and the creation of a hydroponic system is just a very excellent and profitable option.
The following advantages can be highlighted:
Hydroponics can be placed on a windowsill;
For your information: When selling flowers, it is the hydroponic method that is used for rapid distillation.
In hydroponics, the plant is placed in a tank containing a special substrate.
It has the ability to absorb liquid into itself, which contributes to the continuous wetting of the roots, which provides looseness for good aeration. The substrate can be expanded clay, gravel, peat, etc.
As elsewhere, there are disadvantages, but they are much less than advantages.
These include the higher cost of equipment than buying soil. But this is if you do not want to waste your time on making such a system yourself.
Even if you decide you need to purchase a ready-made system, it will still pay off for you in the near future, because the plants will grow much faster and they need minimal care.
First, we need a simple device made of a plastic vessel, foam and an aquarium air compressor. This system will be represented by a container of liquid, with a sheet of foam placed on the surface, which will hold the seedling pots.
For your information: As such a container, it is better to use a container with a black matte surface, since a transparent one will facilitate the passage of excess light and correspond to provoke the formation of algae.
Also, a transparent container can simply be painted on the outside with a dark paint or use food foil for wrapping.
Holes are drilled in the foam, equal to the number of pots, of such a diameter that the pots would hold firmly in the hole.
Hydroponic pots are better for special ones, which are thin plastic strips collected in a planting container. However, they can be completely replaced with ordinary disposable cups with many holes around the perimeter.
If the amount of oxygen received is insufficient, the root system in the liquid can rot and die. Whatever this happens, an air cleaner for aquariums is installed in a home-made device.
It will help the plant obtain the required amount of oxygen bubbles directly from the solution itself. And to balance oxygen saturation, aquarium stone sprayers are used.
After the device is manufactured, start planting.
The pots are filled with the substrate. It is of mineral origin in the form of gravel, sand or glass beads, and organic in the form of peat, sawdust, moss, etc.
The most common is the use of mineral fillers, which can be reused. But do not forget about its processing to prevent the penetration of pathogens to the plant. A 0.3% sulfuric acid solution can serve as a disinfectant.
Important: After you have treated the filler with sulfuric acid, it must be rinsed at least seven times under running water.
The plant is then placed in a pot filled with substrate. If you are going to sow seeds, you will need a substrate made of moistened mineral wool or moss.
Important: Do not plant seeds in coarse materials such as gravel or perlite.
The nutrient solution is available from any gardening store. It should be poured until a third of the pot is submerged.
The liquid level should be monitored and refilled periodically. In the hot season, this is done more often, and at other times of the year, about once every two weeks. Once every three months, the solution must be completely changed.
Dill, parsley, lettuce, and onion are considered to be the simplest ones for hydroponic home growing. Also, strawberries, tomatoes, cucumbers from your own windowsill can be grown on your windowsill all year round.
There is an opinion that hydroponics is harmful. After all, the basis of a hydroponic solution is chemistry and many consider it harmful. But this is just another opinion. Scientists predict that such technology in the future will be on a par with agriculture, and may even replace it completely. And you are given the opportunity to become one of the first and try to grow plants without soil at home on your own.
