+## Full-Auto mode and Web-UI tweaks (May 2022)
+
+The next step in automating the workflow is the "Full-Auto mode".
+This allows the user to enter the required fertilizers and plants at the beginning.
+The machine then first stirrst the fertilizers, dispenses them as needed, fills the tank, waters the plants, clears the tank from water, fills the tank again with a bit of clean water, empties that and finally lets the hoses run empty.
+
+This not only reduces user-interaction, only requiring button presses at the start of the operation.
+It also reduces the possiblity of fertilizer-water-mixture remaining in the hoses and tank, which causes algae growth.
+Running the hoses empty only works when kickstart pumps are added to each valve, of course.
+
+While doing this, I also slightly re-designed the web interface, reducing the size of the graphical indicators, so more fit on the screen.
