Mobile phone/web controllable/automatic watering

This system works best for ebb@flood hydroponic system in the greenhouse. The water on/off (or any other) greenhouse (and house) relays can be controlled from anywhere from the world. It's also possible to make everything automated depending on the humidity/temperature for example. If the humidity gets too low in the greenhouse, the sprinklers can automatically turn on to raise the humidity in the greenhouse etc. Working with automation/web controls is yet another side hobby of mine.
