That's what I am gonna do find a nice spot where there is some kind of water source near. Then I'll buy a submersible pump that works on 12v. I'll burry the pump in the pond and run my water lines under ground to the plant. Then every time I want to water I'll walk back to the spot with my battery booster jumper pack used to start a car hook up the wires from the pump that are somewhere near the plant and then we have water pumping to the crop.
Another trick I use to keep deer and animals away go out there with a cheese grader and a bar of ivory soap this way you also aren't leaving DNA out by your plants.
