What makes "Hydroponic" a unique way of "Farming" as compared to soil based cultivation.?

Hydroponics Farming is more "Safe" and "Secure". Each necessary nutrient is provided with a measured and accurate quantity.  A better alternate for sunlight is available in the form of "Grow Lights". The "pH" and "EC" of water is maintained throughout the growing period. Under controlled Environment, It is also possible to achieve optimum "Temperature" & "Humidity" which also help a plant to boost in a more perfect way. These are the few prominent factors that make "Hydroponic Farming" unique to grow plants more faster than the "Soil".
