For the whole semester, we did a lot work on the roof. At the beginning, we got rid of the weeds of the planters on the floor and the modules on the wall. Some plants are growing well, although some weeds were there. We planted several fruits, like tomato, on the left side of the roof. So far, they are healthy and pretty.
Two weeks later, we started to make some new modules. Base the amount of the soils, we decided to make 18 modules and separated them into 2 groups first. It was hard to bring such a lot of soil to the rooftop, but eventually, we did it.
We aligned the modules into two groups by 3×3. Then we filled gravels and soils with different percentage into those modules, for the future research.
I learned how to prepare for planting, it is good to know how many pounds of soils we need/have before we getting started. I have also learned the process of process of preparing and planting.
