Ladies and gentleman, and the one person that didn't find my previous comment helpful, I'd like to expose homebrewer for who he really is. First he insults my intelligence by mocking me about learning what heavy metals are, then he fails to provide any sources for his erroneous claim. Well, I took the liberty of getting the source myself just to prove a point of why I went at this guy so hard. Here you go community:

Please pay attention to the heavy metal analysis.
Homebrewer, you will not ruin these forums with misinformation for as long as I'm around.
Well you found one link (the state of Oregon also tests agricultural products) but you clearly have no idea what you're looking at.
Take for example the mercury reading of 4.1e-005, do you know how to read that number? Do you know the difference between the heavy metals that you want in your plant food and the ones that you do not? Do you know the acceptable levels of 'bad heavy metals' that plant foods are allowed to contain? Do you know how states came up with those 'safe ranges'?
You've got a lot of learning to do, best of luck! Might I suggest you fix the bruise on your ass first?
