Hammer Head from AdvancedNutes - 2.3400 ppm Arsenic :puke2:
I don't trust Oregon's testing program at all,look at what they said about @capulators og biowar?that was a crock of crap as alot of us know how well it works.I think cap even had it tested at a university afterward and they hot completely different results from state of Oregon.
I'm not defending nute companies at all,most are straight rip offs but I don't trust oregons testing program either.
According to that Arsenic is naturally occurring in all sorts of things,38th on the list of what makes up rocks in the world ,so organic isn't the resolve either with it found in fish and plant material .. it's all within acceptable levels ,so maybe it's not an issue .. just seems if one could grow herb without it ,wouldn't be a bad idea ..
Yea you guys are way too concerned about arsenic.
Considering many patients who need cannabis have weakened immune systems and/or kidneys I question your reasoning for this? I am personally much more concerned about heavy metals like cadmium, mercury, lead and chromium and pest residue but yeah......Ill choose not to lick off the arsenic loaded salt lick too.
If you're concerned about heavy metals you should do a foliage test between organic and synthetic fertilizers and see which one has more heavy metals in it...Anything grown in dirt will have WAY higher of a heavy metal content vs something grown in a synthetic-based medium, simply because many heavy metals already exist in soil whereas in a hydroponic formula calling for only a few different salts, you only really deal with precipitates in the medium and whatever (minor) impurities are in the salt.
