Hormones : Gonna need lots of help with this one!!

Thanks to the wonderful people here I am starting to understand this advanced science with many many variables!

As soon a plant sprouts it tries to flower. The first two weeks are spent building things flowering requires. Once this is done it starts to produce flowering hormones.

But the flowering hormone is degraded by light. The plant builds up hormones all night and the sun comes along and kills them all. this cycle will repeat. Eventually days get shorter and nights get longer. More hormones are produced than the sun/light can kill. Each day more and more hormones survive the sun/light until they finally hit the right level and only then will flowering be induced.

It should be clarified that (most) hormones don't have a direct effect on plants. What plant hormones do is activate a signal cascade resulting in activation of genes which give response that is observed. Changes in concentration or usage of isomeric hormones has differing effects, thus the multiple effects seen from one hormone depending on the application method strength.
thanks spurr

There are seven major kinds of plant hormones:
auxin,cytokinins, gibberellins, brassinosteroids,
oligosaccharins, ethylene, and abscisic acid

The effects of a hormone on a plant often depend on the stage of the plant's development.

Plants progress through a cycle of growth stages. When a plant is under stress at any given stage of growth, it will produce less cytokinin growth hormones. If this reduction occurs at certain key stages of growth, yields are affected. By making available extra hormones to the plant at these stages, you can influence the plants final yield. Timing of the application is essential. If you apply a hormone to a plant, the result will be stimulated growth of the type which the plant is currently under going. If the plant is forming roots, more root growth will occur. These natural hormone compounds are essential to: plant cell enlargement and division - germination - root development - flowering and seed formation.

The correct usage of auxins and cytokinins used at varying ratios and times during the grow and flowering cycles can greatly stimulate desirable effects in plants. Auxins used in early grow, promote adventurous rooting, help relieve plant stress, and promote plant health/vigor.

Cytokinins, used during early bloom, can greatly aid in setting up a better plant structure (short squat plants with close internodes), and used thereafter can stimulate cell division (growth rates) and as a result increase yields.
All nutrients aside, balancing of the auxin/cytokinin/gibberellin chemical equation is the real key to maximizing your specific strains potential.
Mixing gibberellins with both auxins (IAA) and cytokinins (6BA) gives the treatment a synergizing balance and can exceed these limitations (i.e. a hardy ‘stretched out’ plant that is dense and full).

When the auxin concentration is lower than the cytokinin,
explants will induce shoots, otherwise it will form roots.


That said the ratio, timing and type of hormones used will vary from stage to stage and is strain dependent.

stages:

Clone,teen,veg,pre-flower,flower initiation,bud set,bulk up ect.
For example
A super stretchy strain would get less auxin
A overly compact strain could get some brass. but less BAP per say.


So I guess what I am looking for is a base ratio on middle ground.

Cannabis grows so voraciously on her own, you don't need to play with hormones to unlock her potential.... just focus on dialing in your environment; coupled with quality genetics and she'll give you all you could ever need.

Hello shaggyballs.

I see you found spurr's threads. That is the most advanced research available here at ICMAG. If you've read it all, you know more than most of us.

He never got PGRs dialed in that I remember. Good luck with your effort.

Have a nice day. bg

just say no ,ask bog what happens when you use sensi soak and the use those fem plants to make seeds ,

shaggy once you figure out hormones, its cake after. You are also going to notice sometimes hormones are not good to apply.

you can turn sativa looking buds into indica looking ones.
