Fruits, veggies, fish and prawns all grown in a small house in Delhi

Delhi resident Peter Satwant Singh transformed his home in Sainik Farms into a sustainable haven when he learned that unprocessed, sattvic food could aid his wife Neeno Kaur's recovery from leukemia.

The Singhs advocate for waste management and have implemented rainwater harvesting, greywater recycling, and composting. They use vermicompost made from kitchen waste and neem as a pesticide, avoiding the use of chemicals or fertilizers.

The couple's home garden yields a variety of produce, including lettuces, spinach, parsley, tomatoes, onions, radishes, carrots, broccoli, guava, figs, grapes, and plums. They also grow maize and mustard, while three ponds provide fresh fish and prawns.

In 2013, while staying in Goa to avoid Delhi's pollution, the couple discovered aquaponics to ensure a sustainable source of organic food. Over the years, their small model has expanded into a greenhouse, rooftop garden, fish tanks, and vertical farms with over 10,000 plants.

In their commitment to sustainable living, the couple conducts online courses on aquaponics for residents in south Delhi and Gurgaon. They are also developing a small aquaponic model for a school, aiming to teach children about sustainable living. The septuagenarians aspire to achieve complete sustainability, looking into home-installed solar panels and atmospheric water generation for future self-sufficiency.

The septuagenarian couple, even after Kaur's recovery, continue to embrace sustainable living by cultivating their own fruits and vegetables through aquaponics, maintaining a fish farm, and regulating temperature without conventional heating or air conditioning.
