Oooooh I see!
I didnt know its a growth hormone.
There are actually alot of articles when you google
Plant Growth Regulator(PGR) and gibberillic acid.
Natural extracted plant hormone GA would be similar to Superthrive
as opposed to the artificially created PGR.
Ill have to read more of this...
Upon further reading on some google articles,
seems like these growth hormones are more popular with the marijuana culture.
Gibberelins and PGR are the same, its just how theyre made and extracted.
Heres the link that I found...
Hormones /PGR`s/Vitimans - Research Thread Only | Rollitup
Thanx.
