I'm a parent and i'm coordinating a project that takes place in a school in Lisbon, Portugal. It's called Projeto Horta Urbana em Ambiente Escolar (PHUAE) or urban vegetable garden project in a school environment. More info available in portuguese at https://sites.google.com/site/apeeproflindleycintraeb23/anu/projetohortaurbanaemambienteescolar The aim is to grow food with the help of volunteers and, at the same time, sensitize the students to issues like climate change, the importance of soil or organic farming. We have been working since 2013 with the support of the school's board and parents association. We would like to know more about the Grow observatory and how to participate, specially with experiments to be conducted by teachers and students using our project and the soil we have been working on!
