Hydroponics is an amazing procedure by which plants are grown with the help of artificially made nutrient solution, into water, devoid of soil. This cultivation procedure does not necessitate the use of soil or water, bringing in a revolutionizing change to the traditional mode of cultivation. This method has proved to be highly beneficial and very cost effective, bringing in a practical solution to higher yields.
There are two main types of hydroponics solutions namely:
1. Solution Culture
2. Medium Culture
The solution culture does not use a solid medium like soil for the plants, but just the nutrient solution made artificially. Solution culture has been subdivided into three main categories which are:
1. Static solution culture
3. Continuous flow solution
Static Solution Culture
Static solution culture is a method by which plants are full-grown in reservoirs filled with an artificially made nutrient solution. Containers can be plastic buckets, mason jars, tanks, tubs and so on. Containers are generally made out of plastic; however other materials can also be used. The solution used should be aerated but can also be left unaerated. If the solution is kept aerated, then it is kept at a low level so that the roots of the plant can get sufficient oxygen to breathe. An opening is cut into the brim of the container for every plant to come out. A single container can accommodate numerous plants, provided the container is large enough according to the growth size of the plant.
If this procedure is being carried on at home then the method can be carried on in plastic food buckets or glass cans with aeration supplied by a normal aquarium airline tube, an aquarium pump or an aquarium valve. Containers should be covered with butcher paper, thick black plastic, other aluminum foils or any other material that can keep away light which can prevent the growth of algae.
This nutrient liquid is changed according to a schedule or once a week when its concentration level jumps down beyond a definite level which can be identified with electrical conductivity indicator. Each time the concentration falls down, either fresh nutrient liquid or water is again added. A float valve or a Mariotte’s bottle can be used to repeatedly uphold the solution concentration level.
Raft solution system necessitates the plants to be placed on a sheet of floating plastic which is then floated on the surface of this nutrient liquid. This way the solution point does not drop beyond the root level.
Hydroponics has always been considered as one of the most effective alternative to traditional mode of cultivation, and the rapid increase of this method has brought in high yields from countries around the world. This method allows the common crowd to adapt this technology in their homes or private properties. A method like this always brings in higher advantages like the elimination of soil and the cost of water and nutrients. A control method like this will always bring in more nutrition in plants and cause less health hazards caused by pesticides and other chemicals.
