- Plant metabolism researchers have found that the nutrients that plants absorb are simple ions in water. Under natural conditions, the soil is actually the nutrient reservoir, but the soil itself is not essential for plant growth. With the help of the roots, the plants can absorb the nutrients in the soil when dissolved in water. When the nutrients needed for the plant are artificially added to the plant's irrigation water, the plant does not need a rich soil substrate to exist.
- Almost any plant can be grown with hydroponics, but some plants are better suited to it than others.
- These are the two main uses of hydroponics. First, it allows for creating a controlled plant growing environment, removing many variables from scientific experiments. Second, many plant species produce more output in less time, and sometimes of higher quality; This makes hydroponics a profitable tool for farmers in various economic and environmental conditions. When hydroponics is used, there are no diseases that come from the soil, wild plants to be eliminated, or soil to cultivate. Plants can be grown very densely, saving space (you can even grow plants on several floors).
Hydroponics is also economical in water if the containers in which the plants are grown using a closed water system that recycles water. Such systems consume minimal water as compared to traditional agriculture.
- Moreover, hydroponic systems are often used as a solution for vertical gardening, when plants need to be grown above each other.
The leading technique as an optimal growing method is hydroponics, growing plants directly in water or alternatively in a detached substrate without using any soil at all!
No soil is needed
Water remains in the system and can be reused - significant water savings.
Nutrition and fertilizer levels can be controlled - lower fertilization costs.
There is no ecological and environmental pollution due to the controlled system.
Stable and high yields
Pest and disease treatment are simpler compared to soil growth due to container mobility.
No damage from dangerous pesticides.
Another benefit of hydroponic farming is that it’s easy to do indoors. Growing indoors comes with its own benefits such as the ability to grow year-round, temperature and climate control, and fewer pests. Hydroponic systems are usually implemented indoors because of the environmental control it offers. With near-perfect growing conditions, plants grow stronger and faster.
In hydroponic farming, plants grow healthier than in soil.
For one thing, soil-borne diseases aren’t an issue in hydroponics because there is no soil for those diseases to fester and spread in. Plus, plants don’t have to spread their roots out in search of nutrients so they get to spend more energy on growing.
Hydroponic growing systems are sensitive to power failure. The pumps that provide the nutritional solution to plants need to be turned on. During a power outage there is a danger of rapid drying of the plant roots.
High initial expenditure compared to growing land.
