Gibberellic Acid ?

[videoman40]

Does anyone know anything about Gibberellic Acid ?
I read the following online and found it interesting.

How Do I Use Gibberellic Acid (GA3) To Generate Bigger Plants?
Yes. This is a well-researched area, although the results of gibberellic acid (GA3) applications vary depending on many factors, including (here also) the type of plants its applied to. In one study of persimmon yield (1) it was found that applications of 15 to 30 PPM increased yields by 50% to 400%. In another study (2) it was even found that if gibberellic acid is applied to a plant the next generation of the plant would also benefit from faster flowering and increased height. In another study of walnut trees it was found that applications of gibbarellic acid (GA3) increased growth by 567% (3).

Gibberilic acid causes the internodes of the plant to increas, and make it streatch. And form what I've gathered it's probably not the respones that your looking for.

GA3 however can be used to help break seed dormancies and improve germination

 

[ILoveUMaryJane]

What I found suggested it will increase internodes (as WorBlux said), which isn't really that good a result - i'd save your money to spend on something more fundamental (after all, it's the fundamentals that make the real difference), like lighting, medium or nutes

SO I CAN USE THIS STUFF ON MY strawberry cough plant that has been flowering for about a month or 6 weeks and get seeds. Thats really cool cuz i got a clone and its for sure producing seedless bud and i really wanted seeds to grow this strain again.im gonna try it and tell everyone here if it worked or not in about a month.

and also get all feminized seeds

It does seem difficult to find info on gibberellin/gibberellic acid use on ANY flowering crop, much less crops that are grown "guerrilla." What I do know is this: an application of any growth hormone requires the plant to have a lot of stored energy (well-developed root system in nutrient-rich soil with plenty of light) otherwise the plant will exhaust itself and die, or simply not respond. Gibberellin PRIMARILY induces longer stem (internode) growth but is used in agriculture to both break dormancy and encourage fruiting on commercially grown apples, pears, and citrus fruits. As flowers are the precursor of fruits, and flowers are what we all want, there seems to me to be some potential for the use of gibberellin on our favorite flower crop. However, dosage rates for different species vary dramatically and too much is a sure killer. The most important thing to keep in mind is that gibberellin, like auxins, micronutrients, surfactants, etc. is an ADVANCED technique. This doesn't mean it's only for genius growers; rather, it means that ALL BASIC NEEDS MUST BE FULLY MET prior to expecting results from these cutting-edge techniques. For example, if your medium isn't supplying ample manganese, iron, or even phosphorous, forget it. You will get better bangs for your bucks by focusing on improving the basics than by experimenting with hormones. The best I've ever smoked I grew myself under flourescents in regular potting soil and vermiculite using only 2 different multinutrient fertilizers: 1 for veg, 1 for buds. I do have a supply of gibberellic acid and am experimenting on a few individuals in my current garden. If anyone else has firsthand experimental or relevant horticultural knowledge of the use of gibberellin on flowering crops, please reply!

to turn your plant into a hermie. Has uses, but not for most. Great for the veggie patch though.

 

[jackdirty]

so does it really feminized seeds?

 

[MediMaryUser]

i didnt do it lol but i think it makes feminized seeds only if you pollenate one female with another female not the female gone hermie lol

 

[skokie]

No, it does not cause feminized seeds. It can however cause larger buds and, if you have pollinated, gibberellic acid will help the plant to develop more seeds. It rarely causes additional stretching when applied during flowering. It will also help seeds germinate. It is used in great success in hydroponics as there is typically ample micros and macros available as bud production goes into overdrive. It WILL lengthen flower times a bit.

 

[Kreyonic]

Actually, G. Acid causes the plant to produce male flowers during female flowering, in turn self pollinates which in turn also creates Feminized seeds. This is just research that I have looked into for creating Fem Seeds BUT... Be very careful when messing with G. Acid. It is VERY toxic. If you want to use it, make sure you do all the research before fully jumping on the wagon. And I dont mean research as in asking on forums, look it up on the web, read it in horticulture books or marijuana techniques. There is a small article in the Cannibible about this same thing "Cannibible 3, Pg. 118" which explains this acid pretty well.

I hope I dont come off as an ass, I really am trying to help

 

[BigBudBalls]

Each seed pod is a pod that has been pollinated. No pollen, no seed.

GA will, as stated, cause the male flowers to start. AKA, a hermie. You don't want to self pollinate a plant. You want to use that GA pollen on a separate plant (not a clone from the same mother)

 

[Vindicated]

This is a good topic

So what are the risks when using this stuff for germinating seeds?

Why wouldn't you want to self pollinate a plant? What if you had an elite clone and wanted seeds? Wouldn't you be likely to get a close match to the origina?

if you have 3 plants, all clones from the same mother, its genetically, one plant. To force male flowers and using that pollen on any of the 3, the seeds will most likely be hermie seeds. (think inbreeding)

2 Different mothers is a much better/safer way to go.

If the plant is that special to you, just keep cloning her (plus it wlli always be a female.)

lol your icon and inbreeding!

god damnit has any one succesfully used it?

Gibberellic-acid a chemically produced natural acid, not a hormone preparation which stimulates the production of female flowering hormones that are already present in the plant. Every cannabis plant contains Gibberellic acid by nature in his/her system. Some very extreme Sativa's may show a tendency to hermafroditism.Preferably use the spray shortly before you turn off the lights. You can also suspend the light higher for a few hours.

A 1000 ml. bottle of GA-Special Spray is enough to treat 500 plants. Spray well above the plants - do not dilute.

Spray the plants once after they have been blooming for 23-26 days, or 23-26 days after you have switched the lights to 12 hours.

For insiders: the change from the first to the second internode flowering is the best moment for treatment.

Direct use in the nutrition solution is also possible. This way you can treat twice as many plants as compared to spraying. Use No Mercy Supply GA-Special only once in this case. For more info contact No Mercy Supply ( [email protected] ). The results of using GA-Special will show up rapidly and you will be surprised by the results!

sounds good to me

I Know this is an old thread and maybe many others regarding GA but a friend of mine pointed this thread out to me and thought I should clear a few things up regarding GA.

1)
The ONLY reason it is better to use the pollen on another female plant in flower over the one forced to produce male flowers is YOU GET FAR MORE SEED. There is NO evidence to show that seed actually from the herm would produce seeds that are more inclinded to herm. (@ Correct dosage)
2)
GA IS TOXIC TO PLANTS AT THE INCORRECT DOSAGE.... Start with a number of females and spray each with different strength doses recording each.
3)
Some cannabis strains interdodal distance is increase SERVERLY with GA .... You may need hieght. Prune... trim ...Top..Fim ... what ever you like ...I prefer over 5 weeks vegging keeping all stems down to 2-3 nodes...... before treatment.
4)
The increase in growth triggered by GA requires the plant to have a large amount of stored energy..... this means spray on well vegged plants (under Quality light) to get quality FEM seeds, plus spraying on well vegged plants means there is less chance of your plant dying on you. Your plant must be in PRIME condition and not recently cut.
5)
Soaking seed in GA can increase the germination rate (although experience beats GA). It DOES increase the female to male rate to some degree for alot of strains. Some I know it either kills out right or you end up at such a weak dilution it makes no difference.
(There is a rumour I heard many years ago which said that soaking cannabis seeds in a solution made from crushed chrysanthemum bulbs and water overnight has the same effect... I have not tested this theory, but I can find no scientific evidence to back it up, or show any significant increase in the bulbs naturally occurring GA)
6)
Using Ga to increase bud size.... forget it. Never heard of it, never seen it. Far better and safer options/products out there.


I have found GA a good and cost effective way of increasing my chances of locating and isolating a certain genotype from a strain where the strains seed cost was at a premium and there where many genotypes dominant over the one I required. (Produced more seeds instead of buying more, if geno not produced from original purchased seed)

To all that read this GOOD LUCK in your experiments.
From forums you can gain much useful advice ........ but remember true knowledge comes from personal experience... and Google Scholar
