Divine Seeds Contest: Auto Opium (and probably my last grow)

So this is my second legal grow, and extremely lucky(!) occurrences have led to the conclusion that it will very probably be my last grow too. In fact I am doing it only because I feel obliged to @DivineSeeds granting me two packages of seeds to enter the contest although my first grow was not completed. I put 3 seeds into RO water yesterday, did not examine them for any signs of germination but put them into soil today. Only the two big 20 l pots will participate in this contest. If they germinate of course. So the success rate is a lie at the time of writing. I’ll update it later. Graphics are from a self-built Growbox control using two Raspberry Pis, an Arduino, a camera and a lot of sensors. During all phases below drying, the software tries to stay within the "green" VPD range, switching the main blower, a self-built humidifier and more small fans and blowers. Lights are turned to 20% currently, the lowest dimming value possible, which means 2 x 10 W. As there is nothing to see yet and the Raspberry Pi2 has lost its sense for the camera, real-time images are currently disabled. The first soil humidity is not really soil but the filling grade of the humidifier. Soil humidity values 2 and 3 are the big pots.
