Distance Learning Hydroponics Course
“A detailed introduction to hydroponics”
Develop a sound understanding of the theory and practice of hydroponics. This is a serious grounding for working in the hydroponic industry and concentrates on the horticulturaly valuable crops, such as cut flowers and vegetables.
