Plant Hormones

[Tom Barr]

Tom, thank you for the explanation and addressing my concerns. Very helpful!

Cheers,

Well, the reality is that it's an unknown, but the practical evidence is EXTREMELY skeptical that there is ANY impact.
I have some plant nursery root hormone for scion cuttings and other land plants.......I've used it as a dip for some plants like Ammania and other species that tend to stunt for long periods without any effect.

This product should be far superior than any that ADA makes.

Actually ADA does NOT make it...they buy it and then repackage things.

Thank you! Couldn't find such detailed informations.

Does anyone of you know how concentrated the pgr's in coconutwater and pineapple juice are? I want to apply a mixture of both to my aquarium as a cheap alternative of 'green gain'. It is just a test don't know if it works.

best regards
Alex

C2H4 is the gas that allows plants to sense they are submersed, the C2H4 does not leave as fast in water and diffuses 10,000X slow, this causes an increase and the plant responds to flooding(See Jackson et all for a model of this) which ultimately results in expansin genes that cause elongation to bolt to the surface of the water, this is very different however than root initiation.

The Latter references are good basic gardener type methods, and dips for stems are commonly used.
Squirting a few drops of something in a large fish tank is not the same as dipping a stem into a 1000 ppm of a PGR.
The Spray is 50-100ppm, but I doubt there's anywhere near this amount in Green gain.

Few will dip their stem plant tips into such solutions just to get them to root a little bit faster, they root fine on their own.

If you did a massive water change and exposed the plant's leaves to air, then sprayed.........it might be okay.
I just do not see a lot of use when you trim the weeds monthly or more frequently.

They can only be messed with so much, before basic growth factors are more important. They MUST have the resources to allocation the root formation and stem elongation in response to PGR's. It's like having a boss that wants to build things but no bricks to do so.

Hi Alex.

another German on board, welcome to you!

You know how to deal with algae? .....otherwise be careful. Once I introduced coconut water to my 20g (about 20-30ml) just for testing reasons. It was followed by an algae outbreak. Can't remember what exactly started to grow. But I think it was BBA. No change in plant growth by the way.....as expected.
