Olivia Phillip, a grade six learner at Otjomuise Primary School in Namibia's capital, Windhoek, gently applied fertilizers to water at a shaded hydroponics garden at the school.
Soon after, she tested the PH level of the water at the greenhouse. "I have to make sure the water fertilizers are infused in the right quantity and that the PH level is optimal so that the vegetables grow in a nutrient-rich water bed to secure a good harvest," the 12-years old Phillip said.
The garden boosts beetroots, variety of lettuce, spinach, and cabbage. Phillip is one of the 20 learners at the school trained in early 2019 on hydroponics gardening technique, piloted as an alternative way to promote sustainable school gardens.
