Elementary school has new off-the grid, vertical garden

San Francisco’s Sanchez Elementary School has created a vertical garden that is edible and off the grid. Solar panels and windmills provide electricity for the irrigation system, and power a weather station so that kids can monitor the climate and how it relates to plants. The kids learn about plants, science, and food by growing things like mustard greens. Apparently the total cost was $10,000, and the project benefited from volunteers from the Slow Food movement. Great use of a limited space, and great to see kids learning about where their food comes from. Very inspiring!
