Does Anyone Know a good selfwatering planter?

I want to grow outdoors, i have the perfect spot, it so far in the woods, no animals around, no people, no cops, its just all aroound perfect the only thing is im sort of a busy man so i cant get out there all the times, so does anyone know a good selfwatering planter system that doesnt require electricity. And if you have one setup please include pics, thanks

the best self-watering pot is mother earth near a stream.

yup the best way is find a moist area like near the edge of a stream or creek or drainage ditch.......

or try rigging up a giant aqua globe...........lol
