Hang on, don't all plants water themselves?
Well, technically yes. But not if they're confined to a pot on your desk. Who'll top up your beloved petunias when you're off on holiday?
I have a guy for that
You and your disposable income. For the rest of us however, this Arduino-powered setup by Randy Sarafan will enable any plant to water itself without you having to lift a finger.
Is it powered by science?
Of course it is. An Arduino board controls a soil moisture sensor which regulates a water pump, so if you're plant's feeling thirsty, it'll get an automatic top-up. Just don't forget to leave enough in the reservoir when you're off on your island vacation.
I don't have a degree in electrical engineering
You won't need one. Just follow the guide at Instructables and your plants will be watering themselves in no time. Just don't pair it up with a Robotic Action Plant – mobile, self-watering cyborg plants are a step too far.
