Old mattresses used to grow plants, crops

The University of Sheffield has developed a method to use foam from abandoned mattresses to grow plants in the Zatari Refugee Camp in Jordan. This hydroponic farming system supports plants without soil by using a nutrient solution. Researchers have created a scalable system using plastic piping and recycled yogurt pots to facilitate plant growth. This innovation allows refugees to cultivate fresh vegetables for their meals, promoting self-sufficiency.

Describe the process of how nutrient solution is delivered to the plants in this system.
