Hydroponics cultivation is considered to be superior to conventional cultivation because of the numerous advantages it offers. Both commercial scale production and small scale crop cultivation using hydroponics techniques have proved to be advantageous in many respects. One of the advantages of hydroponics is its simplicity.
