On 22 March 2019, we learned about urban planting, that is to use the least cost to grow plants in the city. We started off by making the pots for the plants. George, one of the people in charge of the organization, taught us how to make them. We have to use no.2 or no.5 plastics for the pots as others would be too vulnerable. The roots of the plants would be growing in those pots with just sunlight, water circulation, and bacteria. We painted the pots black so that when the Sun shines on them, water circulation is active. It is amazing that no matter the size of the plants, they can still grow in pots that do not have soil and only with water.
