No, no, you need to use LEDs with a potato battery!

Lets see, that pic I posted... the specs are 4mA/500lbs potatoes, plus you'll need an AC inverter if you want to run your HPS off them, and change them out weekly...

If you can grow that many potatoes to power a HPS, why not just go into the potato crisps business?

This might just be crazy enough to work so I was flippin thru a science book today when i came across this picture that had a solution of NaCI or Sodium Chloride and inside the mixture it had 2 metal conductors and those were attached to some wires that ran into a battery and then into a lightbulb and the bulb was burning bright I dont know shit about science so I was wondering if anyone could verify if this method would work for running maybe 3 or 4 CFLs without any power cords or anything Rating: 5
