Today, we went to changing young lives foundation to teach children from low-income families of the importance of self-sufficiency, and contextualizing the cantonese phrase “粒粒皆辛苦”, which means every grain comes from hard work, highlighting the hard work that farmers go through to provide food for people. We first taught the children how the outdoor hydroponics system works, then letting the children come up and try maneuvring all the steps themselves.
Then, we educated them with some biology information, how important light and photosynthesis is to plant growth, and how different colors of light have different effects on plants. Then, we introduced them to an indoor hydroponics system, which uses artificial lighting and takes advantage of the effectiveness of different coloured lights to promote the best growth. We then surprised them with their own individual indoors hydroponics system, which they can bring home to grow veggies. The reaction of excitement and gratitude from the kids warmed our hearts, us knowing that we have made real tangible impact on their lives. Finally, we compared different urban agricultural techniques, such as aquaponics and aeroponics. Today was exceptionally rewarding, as we know that we have taken a small but important step in alleviating good insecurity in Hong Kong.
