This spring I decided to start some trees from their seeds. The idea is to be able to plant them in a garden area in a few years. I started a lot of different plants but the mandarines and pomegranates grew very well.
Since I am spending a lot of time away from home, I also build a system to monitor, report and water the plants as needed. A little raspberry pi gets the report and also has a webcam where, occasionally, I take a pic to check on it (through a VPN connection).
I was super surprised to see the growth of the pomegranates, within a few days it grew by a few centimeters.
Oh I do, a lot. Which is why I build the system so that even if I am gone for 2 weeks, the plant will get the best possible water routine.
