Auxin is extremely well studied in the research on plant development both biochemically and molecularly.
When you say did I address it, do mean with respect to Yamato Green?
Otherwise that is a different thread.
You can buy Super Thrive for 1.99 for 2-4 oz and add that to the water and make any auxin or hormone claim you wish.
No different than any company's claims, there's scant research on exogenous dosing of Hormones of any sort on Aquatic plant, Dr Kane at UF where I did my grad work is the only researcher I know that's done anything there, it mainly helped some Crypts flower and was a one time event, otherwise, they tend not to do anything in submersed culture.
What they do endogenously is quite another matter, but we really do not seem to be able to amplify growth with their usage. Folks want to increase growth, they should focus on the basics: light/CO2/nutrients.
Let the plants make their own from the basic building blocks.
Hormones are typically used in agriculture for increased fruit and nut sizes, flowering etc.
Not vegetative growth which is what concerns us.
Some do not enjoy break neck or increased growth, but still want to add things like hormones to increase growth, that's counterinitutive and the logic does not follow.
You could add super thrive at low concentrations to YG and make those claims also.
Will it help?
Not that I can see, and there's nothing to support it observationally nor in the research, but there is for fruit and other process, or endogenous controls.
But these are hard to apply to aquatic plant horticulture that addresses vegetative growth.
Some suggested that ADA's products help plants root better after trimming, I really do not want roots I responded. Further, a number of garden centers has several brands of rooting hormone we can buy for 2-5$ for a life time's supply.
YG could be reformulated and have hormones, more PO4, more Mg etc added, then it'd likely do better for many tanks.
But it's not my company either.
Still, it's good, but we get back to a brand loyalist vs a DIY that uses KNO3, KH2PO4 and can tailor their dosing to suit and have a life time's supply for less than 50$.
You think it's worth it to use the pricey stuff, that's fine.
But do not attempt to suggest that it's really better without testing it and being careful in that process.
Be fair.
