Correct that giberellic is a hormone. The amounts of GA3 in plants naturally are extreemly small compaired to the amounts nessesary to force a hermie. No matter how long or how well you flush a plant hermied with GA3 your going to be risking your health.

10 to 14 days for any strain I have played with is enough time to put it back into a veg stage. A plant goes through many many changes during bloom and for this to work the plant needs to be treated during vegitation stage then wait that 2 weeks and treat again so that the GA3 can react and do its thing with the other hormones present in the plant during vegitation. Some strains will revert to veg faster than others so you maybe ok here. However just to cover your ass starting that new clone to try again would be a smart move.

In your situtation you just started bloom then switched back to veg. I suppose what I would do here would be to keep that plant in veg for 2 more weeks treat it again then wait just a couple more days then put it back into bloom. This may just do it and if not your new clone will be nearly ready to go.

I am by no means an expert with all the aspects of Gibberlic acid (GA3) and how they react with weed although I have used it in the past to hermie plants. Hopefully I was atleast some help though. Good luck and keep us posted.

I am not sure I understand the GA for seeds. I did some reading about this and could not find a common scientific logic. Could you explain what you intend to achieve with the GA on seeds?


Oh yea a new clone will be on its way. I kind of thought I might need a few tries since I have never done this before. 1st try would be nice though.

Ok, I am switching the lights back to 24/0 for 2 weeks today.


It is really nice to have someone who is willing to give a helpful bit of advice.

Just figured I would add more to this.

A foliar feed of 100ppm or higher of GA3 is needed to turn a plant to hermie. The GA3 that I used was a powder and you had to mix it with a few drops of rubbing alchol to make it into a liquid then added the proper amount of water to that for the desired ppm. GA3 is not very water soluble and unless your going to flush your plants with somehow with alcohol, smoking that bud is not something I would do. There are various foliar sprays and seedling treatments with GA3 in them (20 to 30 ppm of GA3) and there are folks that use things such as this and smoke the buds which I suppose is fine, its just not something I like to do I guess just because poisonous chemicals (natural organtic ones included) even in small amounts still scare me.

You will want to expermint with that amount of ppm in your foliar feed. I have used as much as 400ppm but the lowest ppm while still inducing the hermie is what you should be working for. Also there are reports that hermaphrodites occurring three or more generations down the line using this process. I have had this happen but honestly it didnt seem like a common accurance for me. Its been years now sence I have screwed with this but when I did it didnt seem like a big issue. I did have plants hermie on me for an extra generation but I planted those seeds and those seeds never went hermie on me. I may have been lucky and it could be a strain thing as well so you will have to experiment and if it does happen just let that plant seed out and plant those new seeds for the next generations eventually they wont hermie.

Hopefully this will be helpfull for other folks and thanks for the +rep

do you use the same EC/PPM meter to determine ppm that you do for your nutes?

No and I am not sure how well this would work either. I just used a mixing chart that I once had. Just search the web for "ppm calculator" and this should help get that "recipe" correct.

I suppose that after you follow the recipe from a ppm calculator you could test it with a PPM meter for shits and giggles but not sure its nessesary. Nore am I sure of the accuracy so useing a calculator and measuring your mix would be the way to do things.

**edited to add**

Now when I said 100ppm or higher this is sort of just a guideline. I have gone as high as 500ppm and as low as 75ppm but I also had some strains not hermie with the lower dose and I also had some plants that were quite adversely effected with a strong dose. Hence the reason to experiment if your attempt totally bombs its only costed you a bit of time and wasted 1 clone so keep at it and dont let minor setbacks stop you.

So you were unsuccessful with rodelization?

I think you just needed to pay a little more attention to the plant, it probably had buds full of bananas you just did know what exactly to look for.

A non genetic hermi will not grow full on male parts, it will grow male bananas out of the buds, and these can be a challenge to find sometimes but this is what you are looking for if you want female pollen.

Otherwise its hermi pollen.

I was not trying to get male pollen, I was just experimenting and let 1 plant go way to long. So was looking at it lot and I had a bunch of other plants in there that were in the first few weeks of flowering and I got no seeds.


A questin for you, How much stretching did you see after applying the GA?

Update:
So the main plant died, it just stretched and stretched and lost all of its green. I sprayed it with the GA spray about 20 times, and pored some in the soil. Clearly too much! The stretching was amazing, the plat looked so weird. The top branches got so long they snapped off and the bottom branches got long enough to seem like they were the top branches. The plant could not process nutes as fast as it was growing. I went and sprayed my sunflower outside just for shits and giggles.
I have another plant that I sprayed just 1 time to see what would happen, about 10 days ago. It has stretched a lot too and lost a little of the dark green. I think I will give this plant 1 more spray and put it in the 12/12 room.
Initially I was not even sure is the gibberlic acid I had was real. So I used more than I thought I needed to be sure I saw an effect. Clearly the stretching is noticeable with the concentration I was using.
I had no mixing chart, just a gram of powder, so I just put a sprinkle (about 50mg) in a few drops of alchol and that in 1 cup of water. So it was a bit random. It seems like you could judge the strength of the GA spray from the amout of stretching I see.

i recently reversed a tahoe og kush with homemade colloidal silver its forming male pods on the treated branch now. i have used ga as well it does cause massive stretching. at low doses 10ppm on plants with many internodes it helps growth on young plants it screws them up. it is used on food crops throughout the us its not nearly as dangerous as people say but treat with caution.

I read something about this, it seems like a good way to go.

Why did you not continue to use GA?
