super supreme futuristic hand watering regulator gun...?

Is anyone aware of a device that would help me simplify and speed up the hand watering process? Like something that would regulate the water flow so I can just walk around to each pot and be able to pull a trigger on something and hit each one with a gallon. Like I said Im just trying to simplify the process and Im not aware if anything like this exists. Thanks and happy 420!!!

I heard of something similar to what you are talking about. I think it was called........a hose. lol
Just kidding.
I would like to simplify the process too! I thought about some sort of gravity feed from a tank full of nute water, but thats as far as it got. There was no room to put it. When I get moved later this year I will have more room to work with.
