What is hydroponics?
The history of hydroponics
Is it complicated for you to do hydroponics?
The classification of hydroponics
- Buffer action - A solution/inert medium maintaining pH and electrical conductivity in a suitable range for the plant root system
- A nutrient solution/ fertilizer mixture containing all micro & macro elements
- Suitable temperature & aeration
So, let’s simply talk about the various methods that we can try in hydroponics.
1. Circulating method (closed system)
In here the nutrient solution is pumped through the plant root system and it constantly passes the root. When the excess solution is collected, it can be replenished and reused.
1.1 Nutrient Film Technique (NFT)
In this method the nutrient solution is not circulated but only once. when its nutrient concentration decreases or pH or electrical conductivity changes.
2.1 Root Dipping Technique
Seedlings/seeds are transplanted in plastic net pots/plastic cups filled sterilized coir – dust/ carbonized rice husks or both plastic cups, some holes should be made at the bottom and on sides to emerge and nutrient solution to get the potting material
Inert solid media can be used in this method but the media material should be flexible, friable with water and air holding capacity. Then only it can be drained easily.
3.1 Hanging Bag Technique
Almost any house plant, fruits or vegetables as well as flowers that you want can be cultivated in hydroponics but as a general rule, solution systems are best for plants with shallow roots. Some examples are leafy greens, such as lettuce and spinach, radishes and herbs. Bell pepper, cabbage, cucumber, melon, radish, rice, strawberry, orchids, roses and alovera are also very famous in hydroponics.
Actually you may gain so many advantages in hydroponics in contrast to the traditional methods. Most of the time, it reduces the problems which encountered in conventional crop cultivation. It provides optimal conditions for plant growth while giving higher yields and it also makes you assure that you are having the ecological values as same as an organic garden. It easily controls over soil borne diseases and pests as well. Also, the flavor and nutrition of these products are also said to exceed that of soil-grown crops. If you can use a controlled environment conditions to this cultivation, you may be able to gain a better yield. So, don’t you like to make a profit to your pocket while gazing at a good scene through your window, every morning? Your own garden!
