Hydroponics is the agricultural method of cultivating plants using only water, supplements, and a growing medium. The word hydroponics originates from “hydro,” which means water, and “ponos,” which means work, this technique of agriculture does not use soil. From plant science, there are no differences between plants that grow in soil medium and plants that don’t grow on soil medium, because in the two practices, the nutrients need to be broken up in the water before plants can ingest them. The distinctions live in the method through which supplements are accessible to the plants. In hydroponics, the supplements are broken up in the water, and the fluid goes up the base of the plants, which take-up the solution toward different parts of the plant. In the soil based, the segments adhere to the soil particles; go into the soil solution, where the plant roots consume them. Hydroponic systems are characterized by various types including the followings:
- Closed hydroponic system
- Open hydroponic system.
The hydroponic frameworks that don’t use developing medium are generally known as closed systems, whereas hydroponic structures with developing medium in a compartment might be closed or open based upon whether the supplement solution is recycled or is introduced on each water system cycle. In the closed arrangement, the supplement solutions are continually reused, observed, and balanced, while in open arrangement, the supplement is disposed of after every nutrition phase.
Another way of characterizing hydroponic frameworks is on the flow of the supplement solution: we have active hydroponic systems or passive hydroponic systems. The supplement solution is forced to flow by a pump in an active hydroponic system, while a passive hydroponic system depends on a wick. Others categorize the hydroponics with recuperation or non-recovery method. Recovery is the time when the nutrient solution will be re-established into the framework, while non-recovery infers that supplement solution is introduced to the germinating medium and is depleted after.
One of the least complicated and most established hydroponic methods. It’s regularly viewed as a “passive” system since it doesn’t require water or air pumps to work. In this system, water and nutrients move from a reservoir to a plant’s roots using a wick. The plants are suspended in developing media and held up the oversupply of supplement rich solution. One end of the cord is set in the growing medium, and the opposite end drops into the nutrient solution. The wick is typically made using absorbent rope or fiber and rapidly soaks up the supplements while conveying it relentlessly to the plant roots. Wick systems work exceptionally well for small, home-grown plants, and this is an excellent choice for a home-based hydroponics framework. In any case, it’s essential that the developing media utilized can properly move supplements and water
Of all dynamic hydroponic systems, water culture is the less complex. Styrofoam is used to make the medium upon which the plants grow and floats on the nutrients solution. Oxygen is supplied to the base of the plants by an air pump which also supplies air to the air stone that air pockets the nutrients.
EBB & FLOW
The Ebb and Flow framework work by momentarily flooding the growing medium with supplements and after that sapping the fluid once again into the storage compartment. The flow of the supplement solution is actively controlled by a submersible pump connected with a timer. The fluid with nutrients is forced into the germination medium when the pump is turned on by the timer. When the timer stops the pump, the nutrients solution streams again into the storage compartment. The clock is set to come on a few hours each day.
DRIP SYSTEMS RECOVERY / NON-RECOVERY
Drip systems are presumably the most broadly utilized kind of hydroponic framework. The use is straightforward: a timer controls a submersed pump in this system. The clock switches the siphon on, and nutrients solution is siphoned by the roots of each plant by a tiny trickle line. In a Recovery Drip arrangement, the supplement solution that keeps flowing is gathered back in the storage for re-use. The Non-Recovery method does not accumulate the nutrients solution.
NUTRIENT FILM SYSTEM
The timer for the pump is not required for the Nutrient Film Technique since there is a steady flow of the nutrients solution. The supplement is guided into the growing tray and flows over the roots of the plants, and afterward releases fluid indeed into the storage. Other than air, there is no any other growing medium, and this reduces the cost of replenishing the growing medium after every yield.
