Northern Lights, 3l Airpot

Little lady is a bit light green but I increased the nutrients a bit and enabled my automatic watering again. Part of automatic watering is a 3d printed self-draining saucer that was especially designes for 3l Airpots to fit on the posts perfectly. It's specialty is that the saucer is slightly shaped like a funnel, so it collects the drain automatically on the outlet. Here is the 3d-model if someone needs it: https://www.thingiverse.com/thing:5341952 The pump for the nutrient solution is a small peristaltic pump that is connected to a relay board on a Raspberry Pi. Also new is a piezo-pump that bubbles my NL reservoir. Not sure if this has any positive effects but work needed was small and it's unhearable silent. So why not 😜
