Coming in multiple colours, the 21st-century allotment garden is a piece of realizable aquaponic furniture, in which both fish farm (aquaculture) and vegetable cultivation in water (hydroponic) are initiated and operated on the basis of the cradle2cradle principle. Full nutrients in fish faeces are absorbed by plant roots, and therefore, serve as organic fertilizer. This is the way by which the plants purify the water for fishes and this creates a closed loop.
Installing this agricultural system on a protected balcony or in the middle of a kitchen could deliver resource-efficient fresh and organic groceries.
