LMAO, I know what you mean though. I see your point a bout growing, putting your pots on carpet, and not using a tray underneath the pots. Every time I would water I would give it enough water, like probably 99% of everyone else does, to run thru the holes in the bottom of the pot. With that being said, I can see how that water getting on the carpet could cause mold, and other unwanted nasties to come about. I can also see it staining the carpet as well. Maybe putting down a little cardboard to help soak up some of the run off would help, maybe even using a $0.20 tray underneath too, cheap solution, fast solution. But......I also understand that the guy is doing an "experiment", maybe not in the best "lab" setting as we all would like, but it is just an experiment that's only going to cost him time, and a little bit of money, maybe none at all if he already had the stuff available.
It would be ideal to set the experiment up in a "static room", so that way you can rule out anything interfering with the end results. Eliminating variables is the first rule to a science experiment. As they say, it isn't proven until you can constantly replicate the results while doing the exact same thing over and over again. So if he gets an increase on yield, was it because the electrical current, or was it just a great plant, responded better to the nutes than previous plants may have. Hell, for all we know the carpet could be a contributing factor in the bigger yields, but we wouldn't know that unless he has a control, as well as another plant set up the exact same way, with the electrical current and set away from carpet. Maybe the carpet helps with producing a little extra electrical current....could be possible since you can build up a static charge by rubbing your feet across the carpet. (Side note...that reminds me of the episode of family guy when Peter finds out he can zap people when he shuffles his feet on the carpet, lmao...now I have an image of a guy shuffling his feet on the carpet and zapping his plants) But anyways, hell, now I don't remember where I was going with that....I just got finished medicating lol.
Yea...science...replicating the results....carpet could be beneficial for all we know, but we won't know unless we, or someone tries it. I fully understand your point Jimson, but I don't think the guy was telling anyone else to do what he is doing, he's just trying something new that may or may not produce good, or bad results.
