For Modern Art Oxford's Yard space, Champion responds to the Cafe with a site-specific installation that points at the artificial environments in which our food is grown. The sculptures consist of tiled cylinders, dual spectrum grow lamps which are ideal for growing plants indoors, and plants that more often take on the role of crops in agricultural applications.
