The aeroponic barrel is supposed to be used as growing device in an existing nutrient cycle, either hydroponic (using liquid fertilizer) or aquaponic (using fish). A barrel can be assembled using only 2-3 compact elements. The available vertical space in your growing area determines the number of growspaces of a barrel. It is 57 centimeters in diameter and requires 1 squaremeter of flat space. For each 15 centimeters of added height 12 additional growspaces are provided as 2 inch netpot inserts.
The aeroponic barrel is especially suited to grow herbs and lettuces in dense urban farming situations. The parts provide a means to assemble barrel corpusses and thus grow spaces easily and quickly in your production environment.
Plants get their nutrients from drizzle generated by spray nozzles inside the barrel connected to a pressure line delivering the nutrients.
