Regular checking of the system is mandatory.
 To check the water level
 Flow of water
 The pH of the water etc.
Observations have to be carried out by students and recorded in a register
under the guidance of a teacher. Jennifer Ann Binu of Class IX J who is an enthu-
siastic, responsible and active member of the eco-club and has contributed tre-

mendously to the maintenance of the hydroponics system. We succeeded in grow-
ing lettuce and spring onions in the hydroponics.
You may wonder why we chose to introduce the hydroponics in the school.
We chose it because:

 It helps to create awareness about nature and importance of food in students.

 Team work


 Sense of responsibility

 Enhanced subject knowledge etc.

Hydroponics comes with many incredible benefits



 Many crops can be produced twice as fast in a well-managed hydro-
ponic system.

 Production increases 3 to 10 times in the same amount of space.

 Lesser use of insecticide, and herbicides.
Every type of system has its disadvantages, and NFT is no exception. They are as
follows:

 A Hydroponic garden requires time and commitment.

 A failing pump can kill the entire crop within a few hours.

 It does not work well with plants that have large tap-root systems.

 Roots growing in confined channels can clog the channels.
