 Two float switches are used to tell the fill-height of the water tank.
 The ESP32 also provides a simple web interface to allow the same controls as from the user interface.
 
-Both UI and controller are connected to each other using I2C.
-All relevant signals are transmitted with a simple DB-9 cable.
-
-All this is mounted on an old piece of shelf-board, using some custom designed 3D printed parts.
-The water tank is realized using a generic 5l liquid tank, with two holes drilled for the fill switches. The holders for the fertilizer bottles, as well as the bottlecaps, are specifically designed to fit my 1l fertilizer bottles.

 Most of the parts I had lying around in the workshop.
 I only had to buy the outlet valves after realizing one of the big valves I still had was no longer working.
 Also the pumps, hoses and hose-adapters had to be bought.
