Here is an idea for a vertical garden in a classroom (plus a fish tank). This could also work in other places -- homes, places of worship, community centres, etc. Maybe even outdoors? With a mesh covering over the fish tank, the cats couldn't get in.
I want to put these indoors and outdoors so I feel the inner outer living Vertical garden of ferns! How about a variation of this leaning against the south side of the front yard or the north fence in the back yard?
