Honestly, I really think the effect could be just some kind of galvanic effect. Potting soil is moist, has a non-neutral Ph, and has trace metals hanging out. So if you stick a zinc-coated or copper wire in that, it'll probably start to react in some way. So the effect may still be "electric", in a sense, but not by harvesting "free energy" from the environment. Also, ions directly from this galvanic affect might be working like a kind of fertilizer by being more bio-available somehow (I am not a botanist). > why not just use a fixed source/oscillator and find the optimal parameters Exactly. Don't leave it to chance and figure out what's viable. Also: use something unlikely to chemically react with the soil. |
