JoeQ Posted April 28, 2022 Share Posted April 28, 2022 I was just reading up on iron, particularly Edta vs Dtpa iron. Which got me thinking, how are these irons diffrent from the old timey method of burying a rusty nail in your substrate? Does the nail breakdown into one of the 4 letter forms mentioned above?

lefty o Posted April 28, 2022 Share Posted April 28, 2022 beyond my knowledge level, but i would suspect that it would depend greatly on the exact composition of the iron the nail is made of. Link to comment Share on other sites More sharing options...
JoeQ Posted April 28, 2022 Author Share Posted April 28, 2022 @lefty oI don't recommend the rusty nail method. I tried this before trying pottery clay, it made my room smell like an old iron mill!!! It took me forever to find that blasted nail! 🤬🤬🤣 Link to comment Share on other sites More sharing options...
