@ibbzy, It is completely self-built and consists of two tanks, each with an irrigation computer and a water pump. These are connected to 32 nozzles in the tent on one side, and on the other side, I can circulate the water through small sinks for adjustment. Additionally, there is a soil moisture sensor that provides data to the irrigation computers.
