With challenges such as increased urban populations, changing productivity of agricultural lands, and soil degradation, it is important to look at alternative, non-traditional agricultural practices. Hydroponics, the process of growing plants without soil in greenhouses or vertical “plant factories” is one such practice. In this course, you will learn the basics of growing plants hydroponically, think about ways to make hydroponic crop production more sustainable, and create a small and simple hydroponic system to grow leafy greens.
