Sakhiwe Shongwe and Bonkhe Mahlalela are from the small African nation of Swaziland, which is completely surrounded by South Africa. 80% of Swaziland’s food products must be imported, and 40% of the population relies on food aid. The two 14-year-olds set out to change that, creating a hydroponic system that increased yield by 34% and profit margin by 114%.
Hydroponic systems don’t use soil. Instead, they provide the plants with nutrient-rich water which can be recycled through the system over and over. Sakhiwe and Bonkhe found that the hydroponic plants actually grew 180% faster than plants growing in soil.
