Increasing nutrient uptake with electricity is one step away from the Frankenstein jumpstarting a dead guy lol That whole idea reminded of something I read about Bruce Lee. He gave himself some kind of shock therapy that he claimed sped up his reactions and reflexes. It looked like those scam ab workout gadgets but Im don't know what voltage Bruce ran.
I thin electricity plays one of the biggest parts in how everything works though.
Wouldn't it be cool though if we found a 9v battery with its terminals against the stem made a plant grow faster
