Why hydroponics could be the future of farming

Most people in India have grown up on the idea that good water, good soil and lots of sunlight translate into good farming. That may have been true for most farmers, for a great deal of time. But new research and practice have shown that what healthy plants really require are good seeds, good water and nutrients. Plants do not really require soil. And plants need not sunlight, but spectrum. The entire process of photosynthesis is possible when the plant separates the sunlight to soak in the spectrum that it requires. Broadly, different types of plants use blue, red or yellow spectrum. Some use white spectrum as well.

But why should India look at hydroponics?

There could be several reasons why India may have no option but to embrace this method of farming.

The first is that it is economically viable. The figures are indicative, from just one vendor. But as more vendors start entering this field, prices could drop. What is needed is a sound government policy on the one hand, and active handholding of the farmer on the other.
