At work when a new fert comes in that we may want to try we
test it along
side others we use by simply marking areas of grass and testing
product a
next to b, with c being no fert.

The difference is that fertilizers all contain pretty much the
same thing -- NPK and trace elements in various proportions.

ONLY the maker of S'thrive know what's in it. The company
refuses to have USEPA (or other labeling agencies in other
countries) test and label it as other "fertilizers" do, so
there's been no "official" analysis of what in it.

This super secrecy is another point against it. I have known a
LOT of charletans who use the same arguyement -- "someone may
steal my precious formulae" -- as justification for not telling
all.


So I might just use whats left of my
superthrive on some annual seedlings. Maybe one with
superthrive, one with
superthirve and a fert, one with a fert, and one with nothing,

But one thin is certain S'thrive is NOT a fertilizer (no NPK as
far as anyone knows, and at the concentrations recommended
there's be darned little anyway, if there were). I can pretty
much guarantee the ones without a fertilizer will do more poorly
than the ones with both.


and keep all
other factors equal,

Hard to do except in a very controlled environment.

Buy some good fertilizer, instead and grow nice bonsai.

BTW, plants MAKE vitamins, they don't use them, and there's a
considerable amount of research saying that Vit. B can actually
HURT growth.
