Coleman Battery Powered Shower

just saw one and was wondering if that i could rig it up for a watering system?

slide to the left, now slide to right, two bumps this time, BUMP BUMP, criss cross

I have a Coleman Hot Water On Demand System, the lowest tempature setting is still kinda warm. Water only comes out if you have propane hooked up with fuel in it, with the unit running.
If this is what you are referring to, this is the only battery powered system I know about made by coleman - I dont think that would be a good idea.
If you going to use it to water, I would look into a 12v water pump an put it on a timer.

You tryin to use it for a guerilla grow?

yes and there is just a battery powered one, it run about 30 buck on amazon

Yea it seems like it would work you'd just have to carry around some kinda water container with it cuz it probly doesn't come with a very long hose... and just hope the battery lasts long enough to water the entire crop.
