Hydroponic cultivation is an above-ground gardening method that results in the use of water to feed and ensure the proper development of plants, without resorting to the virtues of the soil. Discover the principle of hydroponics, the advantages and the elements to take into account.
Gardening method: hydroponics
The principle of hydroponics
Hydroponics is a method above-ground gardening which takes place in greenhouses, which consists of replacing the earth with a neutral and sterile substrate, such as coconut fiber, clay balls or rockwool. In order to be able to feed the plants properly and to ensure that they develop optimally, it will therefore be necessary to measure and bring the nutrients needed by the plants themselves: it is therefore necessary to irrigate the substrate by water and nutrient solution to feed the plants through the roots.
It is therefore almost indispensable to resort to an automated system to be able to grow plants from hydroponics, because the quality of the water and the quantity of nutritive solutions must be optimal and measured as accurately as possible to obtain good results.
The benefits of hydroponics
Hydroponics offers undeniable advantages for growers:
- It makes it possible to cultivate almost all the plants that one wishes, leaving aside the limits imposed by the type of soil available: one can then afford to cultivate on stony soil or on a waterproofed surface;
- If you have ever used substrates to grow a plant from hydroponicsknow that you can reuse it for another crop;
- Hydroponics can be used to achieve significant water savings, since you dose the nutrient solutions yourself. In addition, these elements are provided by the roots, which reduces the loss of water by evaporation;
- The fact of manage the contributions of the plant allows for better results, the plants grow faster and are of better quality;
- Your crop can not suffer from drought, as water is pumped continuously.
The limits of hydroponics
Despite its obvious advantages, note that the hydroponic culture imposes some limits and needs to take note of certain points:
- If you want to recycle nutrients, know that in the presence of a pathology, the risk of contaminating your plants is greater;
- Since the risk of spreading diseases is greater, you may be more likely to use fertilizers;
- You must be extremely scrupulous about the quality of the water and the amount of nutrient solutions you bring to your plants, because the slightest failure can result in the loss of all the culture. Similarly, remember to check items such as the acidity of nutrient solutions and react quickly in case of imbalance.
