My hydroponics balcony system | Cybergarden part 2

Описание: After we lined out an automation concept (pumps, ESP32) for the irrigation system of the soil based beds, it's time to complete all the hardware to the balcony project before we add sensors and automation. In part 2 we're building the hydroponics setup start to finish and actually test it for the first time.
In part 3 we will built and test the irrigation setup and part 4 we will add some sensors to it!
