Sir, Hydroponic is more than organic. The plant grown in hydroponic, the roots absorb (N P K Mg etc) in the form of only ions of the nutrients. Whether you give it in the organic fertilizer in the soil or give it through hydroponics. The roots of the plant absorb as per their requirement, but only in the from of ions of a particular chemicals.
