This is what we are gonna try to make in PBL. This is kind of just an experient because our teacher and the other third grade teacher have know idea how this is going to work out. They have never done it before. First the contractors construct the base of the vertical garden. Then the environmental engineers go and build the water system. After the whole base and structure is done then the horticulturists go and put on the plants. There are other jobs but those ones are the jobs that build the actual garden.
