Hydroponics at Seisen International

The 10 Week Course

The Grade 2 girls have spent the last 10 weeks learning all about growing food hydroponically - that is, using a nutrient-rich water rather than soil. This particular version of hydoponics is called 'aeroponics' because in addition to getting perfectly balanced nutrients, the plant roots also get plenty of air circulation, providing ample oxygen necessary to carry out metabolic processes. This results in faster growth, larger yields, and healthier veggies - while using significantly less water and fertilizer.

Students tracked growth with careful measurements each week, as well as inspected for pests and signs of disease.
