I don't think those metal levels are particularly high. First, it is stated that the results of the analyses is in parts per million. In solutions this is the same as milligrams per liter. Except for nickel, the other metal levels are reported as "less thans" (<). These are likely the detection limits for the method and instrumentation for analysis. Hence, arsenic, mercury, cadmium and lead were not detected (but there could still be a very small amount there that is "less than" the reported number. Comprenez?

Translation: Don't reach for my seaweed yet?

Thanks Connie I'm not a science person either. I understand now.

I feel better now, and will continue using my Superthrive.
I have been mainly using it for newly planted things, to help get new roots growing quickly.

The Indole3 Butyric Acid is also a rooting aid, I believe.

That was my understanding. I don't believe the crazy claims, but I think cuttings root better.

It's a shame that I can't get it here, or I could further analyse some for you, the ICP-MS that I run in work can get down to ppb levels for metals.
