How the soil-less setup works
From the top lid a spray nozzle or sprinkler (included) is attached to each vertical barrel that generates an aerosol or drip irrigation inside each barrel using the nutrient solution of your choice – being fertilizer (hydroponics) or the nitrates from your fish (aquaponics) via pressure pump (not included).
Since 2017 generation 2 (production, series version) of the 1/6th parts provide an integrated wing structure on the inside of the barrel, that will allow for much simpler drip irrigation from the top.
The aerosol/liquid is applied to the roots of your plants inside the barrel. You could also integrate your own irrigation solution like a fogger. Leafs and fruits of your plants are exposed to natural or artificial LED light and atmosphere from the outside of the barrel.
The liquid exits the barrel on the bottom lid and can then be returned to your sump tank or reservoir and into re-circulation.
The idea is to assemble ring segments and stack them at variable height to provide just the amount of grow spaces that you can maintain. For more information please see pages Quality and Usability and FAQ.
Hanging Version of a soil-less barrel
The top lid can also be used as a base. In this case you can attach 3 stainless steel ring hooks to the ribs that are then used to tighten strong nylon ribbons to hang a barrel to a swivel hook for example.
Each hanging barrel is strapped together using 3 ribbons. According to your lighting situation the barrel can be rotated using a swivel hook in order to assure even lighting for your plants.
The most common use case is to arrange your barrels standing, for example in greenhouses. Please also check a few integration examples on this page.
