I don't think it is - not listed, anyway.

By the way. Sorry about the triple post. Another reason to ditch
Motzarella.

Without going out to look at the SuperThrive bottle (lazy girl!), is humic
acid one of the ingredients in that product? I began using ST this year,
and I can't believe the results. They should hire me as a spokesperson for
the stuff. The pbulbs are far stronger and bigger, and the flowers are
more numerous and also larger.

Many moons ago, when I was experimenting with developing my own,
better-but-much-cheaper SuperThrive (abandoned, due to EPA regs), I began
using humic acid as an additive to the formulation.

I am quite certain of its benefit in soils, as it helps release
otherwise-sequestered nutrients, but I questioned its applicability to
orchid-growing.

I know this is quite unscientific, but about 4 months ago - just before
the time I had to start mostly "ignoring" my collection due to the
various surgeries I endured - I added a liquid humic acid concentrate to
my fertilizer feed tank, so have been feeding with it (it ends up being
about a teaspoon per gallon), and it "looks" like it may be a "plus"
after all, as I am seeing more growth and blooms than I had been (again
I'll state - it's quite an unscientific assessment).

Anyone else have any thoughts or experience?
