New Delhi: Senior Bharatiya Janata Party (BJP) leader and Union Minister Nitin Gadkari has revealed that he uses his own urine to water some plants in the garden at his official bungalow in Delhi and that the plants which "were given urine instead of water grew one-and-half times bigger".

"I have started an experiment in Delhi... I have started storing my urine in a 50 litre can at my official residence in Delhi. It's a big government house which earlier belonged to (Congress president) Sonia Gandhi," Gadkari said, speaking at an event in Nagpur on Monday.
