We made a garden to produce and show the variety of uses of algae. looking at the imaginative possibilities for productive gardens of locally produced energy and food. Each wall of algae has a different species to show a spectrum of colour and an an aeration pump to maintain the algae. See more at www.algaegarden.net or on the metis.
There is also a video here where Brenda gives a great description of the specialities of each of the types of algae (and I am half asleep from all the hard work:)
