This is just an update on the Arduino watering system, everything seems to be going well whilst I am away (I am away for ~a month, till the end of Blackhat / Defcon). In winter the plants don’t require nearly as much water and it seems that after 8 days the water level has dropped only 11.5cm in a reservoir ( read orange bucket ) that is about 60cm across. The orange container is smaller at the bottom, probably around 45cm so an guestimated average of say 50cm for the diameter.
At this stage I was going to do the math to work out how much water had be consumed minus that of evaporation, but I’m too lazy right now.
At this rate that container should keep the 4 plants near it (tomato, chilli, orange, peppers) as well as the palm and the 2 trays as well as the random flower going for about 6 weeks!
Having a look at the stats everything seems pretty stable with the 4 plants :)
