Making feminized seeds

I don't usually knit-pick but I think that pointing out the confusing parts will allow you to rephrase & clarify your question, helping you get the answer you're looking for.

I'm not sure what you mean by "directly from 12/12". If they came directly from 12/12 then where did they go to afterward?

Using colloidal silver on two of the clones you're flowering is standard procedure when making feminized seeds. It may be that the lack of replies is because you don't seem to be suggesting anything outside the ordinary.

 

You could do this but I think you are understanding the concept wrong. When you apply the colloidal silver to the flowering clone, she will start to grow pollen sac's that will drop all-female pollen. You then collect that pollen and pollinate another flowering female plant to your feminized seeds.

The colloidal silver isn't the pollen, it is the agent that forces a female plant to grow male pollen sac's.

But back to your original question, you could take two clones and isolate them in different areas, flower them both, apply colloidal silver to one to collect pollen and then take that pollen and apply it to the other flowering clone and get your fem'd seeds. You will want to keep them separate as you only want to expose the plant's you want the fem'd pollen from exposed to the colloidal silver.

 

this is how you use the C/S.

Very good reply. As little as I know, that answer helped me also, lol.

 

Well, you can pollinate the same plants untreated flowers also.

Either way it's selfing if the clones are from the same mother.

 

So I could theoretically have one plant, spray one side with colloidal silver and pollinate the other half and actually get seeds?

 

In an oversimplified way, absolutely.

 

Yes you can pollinate a plant you flipped. I did it along with pollinating the other 3 plants on the tent.

I have grown the selfed plants seeds 2x with no herms and all females.

This is a highly frowned upon practice. You don't want to keep the seeds that form on the donor plant. By doing so you are increasing your risk of hermaphrodites in the future. The donor plant is already a hermaphrodite technically. When you pollinate a hermaphrodite with a hermaphrodite you increase the odds of getting hermaphrodites dramatically. I pushed the company I work for away from this practice 3 years ago. They brought in a legit PHD Breeder and he agreed with me 100%.

Just a side observation... The seeds that come from a "hermaphrodite to hermaphrodite" cross, are half the size as normal feminized seeds. Germination ratios drop as well.

Just a friendly FYI from someone who does this every day for a living.

So a plant you force a change on is more likely to herm? Why?
If the Genetics are solid and not prone to herm why would that change?

Not knocking a fellah that does it for a living and do correct me but hermie is a genetic trait aye? Sts or cs to my understanding dont change genetics just force the sex change.. If thats true how could it add to hermie probability?

 

The genetics are no longer "stable" once you spray CS or STS. That plant is a hermaphrodite now. That means the pollen being used carries a dominant hermaphrodite trait. You need the stable (unsprayed) plants to make the dominant trait (hermaphroditism) a recessive trait.

This is just like crossing a brown eyed human to a brown eyed human... 99.999% of the time you will get brown eyed offspring. Cannabis breeds very similar to humans in that regard. If you cross a hermaphrodite to a hermaphrodite, you will most likely get a hermaphrodite.

CS affects the hormones in a plant. The hormones affect the alleles of a plant. Through the alleles, mutations occur. These genetic mutations can be very specific and include hermaphroditism.

This is the first time I have seen this argument made in a respectful, knowledgeable way. What I HAVE seen, "YOUR PLANTS WILL ALL BE HERMIES YOU STUPID FUCK" or something along those lines.

As for seed size, I didn't post about this, as I thought it was development time, but based on your post, it wasn't.

I did self this one plant, seeds came out normal.
Same strain I BOTH selfed that plant, AND crossed it with feminized pollen from the same strain. This photo is the result of that "cross"

You can plainly see the "cross" seeds on the left are 50% larger than the "selfed" seeds. This was the same plant, just two different buds.

I hope this post was clear and understandable.
I have absolutely learned something today, thank you.

 

Ok makes sence.. So using sts derived pollen on a female plant would be ok just using it on a separate branch of the same sts sprayed plant would be bad? Does that mean the spray has effect on the entire plant if only a portion is sprayed?

 

My current and first attempt at sts reversing so super interested

 

Now, with all that being cleared up... One way to self a plant that would not cause this issue, would be to take a clone, produce feminized pollen, and then pollinate the mother.

The sts or cs would have never touched the mother, and therefore the hermie trait that was introduced to the clone would be recessive.

Thoughts please

 

I plan to do basically the same thing but going to just take 2 clones and reverse one clone to pollinate the other 1
