DIY Idea, hear me out
Hey all you party people I've read conclusive studies that indicate iron skillets release iron into the food we cook in them. Plants rely on iron, among other things, to grow as part of their fertilization. I'm sure you see where I'm going with this: fellas, couldn't we just boil a cup of water in a skillet, cool it, mix it etc and dump it in during our next water change?
I'm posting this in hopes of being proven wrong, so someone can catch me before making a mistake, so I'll pave the way for you: Either the exact variety of the iron that becomes absorbed into the boiled water is useless to plants i.e. overly or under magnetized or incorrectly bonded with H2O, or the iron is not going to make it into the plants because plants use roots versus leaves to take in iron i.e. tabs versus liquid fertilizers.
Or some new thing that I'm not scientific learned enough to personally conjure.
Or I'm a [censored]ing genius.
Lemme know, thanks ya'll.
