Dear Dr Sharma,
I know a company called Ayurvet limited in delhi. I had Visited their Hydrpponics system manufacturing facality. They showed me their running models which they are selling to diffrent government bodies.
The contact person is Dr Deepti Rai , She is the main person in this company for hydrophonics. Her mail id is drai@ayurvet.com. Her office no is 011 - 22455992/94.
They have many models for hydrophonics and they also sell nutrient solutions for the machine.
Hydroponics for home garden and Commercial hydroponics are two different beasts in my opinion. If you want to do it commercially make sure you get premium price for your produce or it may not be viable in India.
