A couple of years ago, I have installed the automated irrigation system in our apartment. After running this setup for an year, I have discovered some problems during the everyday operation:
- due to the small capacity of the water tank, it was required to refill the tank frequently,
- amount of water delivered to the plants was determined by time (averaged measured value I got with calibration) and was not accurate,
- it was not possible to irrigate plants independently,
- couple of times the whole water tank was used for single watering thanks to basic physics in action and lack of the valves.
In a meanwhile I have decided to automate the watering of the balcony plants as well, but also to fix the problems noticed in the first implementation.

After successfully monitoring the plants water levels and needs for some period now, it was finally the time to automate the process of watering as well. The idea was to implement a simple drip watering system with one single water source. Each of the three existing plants would be irrigated proportionally, based on its demands. During the period of couple of weeks, all necessary components arrived and the system was ready to be built.
The main part of the system is a water pump. This is a small 300 l/h submergible electric pump. This was good choice because of its low flow and the fact it can be easily put inside the water tank in the corner of the room.
