These are the parts to my planned four-plant, automatic watering system. It probes each plant every two hours and applies a short burst of water if the soil is too dry. The entire system runs off a single 12V adapter. An alarm is sounded if the reservoir level is too low. Case is a DC-85P from PolyCase, reservoir is a bike water bottle that sits inside an opening the case. All plumping and wiring is inside the enclosure.
