I plan on growing this year outdoors in a very, very desolate place. I wont be able to check on my grow every day for watering. This is were I came up with the plan to have a cheap irrigation system running off a 12v car battery. It consists of a water pump timer, water pump, reservoir, and a car battery. I have the pump, reservoir, and battery but I have no clue were to find a timer that I can directly hook up to the battery. Has anybody tried a method like this to have a self-watering system for growing outdoors? any help is appreciated. thanks
