“This is how the concept of ‘bucketponics’ came into being,” he says. “The book mentioned that fish excreta in water worked as a source of ammonia and nitrate, which are essential elements for plants to grow. This was proved right in my experiment,” he adds.
The vegetables are grown on the upper tub, while the fish live in another tub installed below. The water from the lower tub is pumped upwards to water the plants, which again drains down into the lower tub for recycling.
