An Indian hobbyist has created a purely organic nutrient mixture for growing plants in water.
Although it is still an evolving science, hydroponic agriculture (growing plants in water solution rather than soil) is spreading fast the world over.
The nutritional requirement of the plants in this system of soilless farming is met by the nutrient mixtures, called hydroponics fertiliser mixtures, added to the water in which the plant roots are kept submerged. These mixtures are made of chemical plant nutrients. This plant growth solution has been tested successfully for growing several plants, including common vegetables like tomato and arbi and some high value medicinal plants like Brahmi, Arjun and Cineraria.
