That pretty much closes the case, in my book. And as was also pointed out, this is the stuff that grows the food that we eat
Folks have to keep in mind that the purity level required in scientific studies has to be much higher. This is where ACS materials come in. Heck, why not feed our plants molecular biology grade (99.99% pure) chemicals?! Now if some of you are doing tissue culture studies on some plants or trying to come up with the latest dwarf variety of something, perhaps you might need purer chemicals. For the rest of us, our past experiences should tell us what does and doesn't work.
