The aponix vertical barrel is a growing device that can use an existing nutrient cycle, either hydroponic (using liquid mineral fertilizer) or aquaponic (using fish, organic fertilizer) much like a normal NFT. A barrel can be assembled using a few compact elements without requiring additional fixed table or rack structures. The available vertical space in your growing area determines the number of grow spaces a barrel can provide. One barrel has a diameter of 57 centimeters and requires 1 square meter of flat space. For each 15 centimeters of added height 12 additional grow spaces are provided as 2 inch net pot inserts.
The aponix vertical barrels are especially suited to grow herbs and lettuces in high density urban farming situations (>60 pieces per sqm, see setup in our slideshow rendering). The parts provide a means to assemble barrel corpusses and thus grow spaces easily and quickly in your production environment. After harvesting the ring segments can be power washed easily, restacked and replanted immediately.
Plants get their nutrients from drizzle generated by spray nozzles inside the barrel connected to a pressure line delivering the nutrients. Version 2.0 can also be operated using simple drip irrigation from the top, practically converting the barrel into a giant vertical NFT. Version 2.0 will be available in large numbers from December 2016!
In 2017 there will be more adapters for bigger plants and also a soil-based barrel.
