It's fine etc.
Will it do much?
Not that I've even seen except in emegent plants such as crypts.
I suspect that the Azoo stuff and other comapnies that sell the phytohormones etc and add them to their products also use something like a jug of Super thrive and add a little in there for safe measure, but they really have no effect in aquatic systems as additives.
Super thrive is much cheaper though than the aquarium based products.
