Tutorial DIY STS Mixing/Using Guide for Feminized Pollen/Seeds R.C.Clarke Method as Base

[Tonygreen]

Nice one. 10mM highest documented spray strength from what I've seen and gathered. Hows your pollen drop?

 

[brickweeder]

harvested and applied the first round of reversed pollen from the CBD Pure day before yesterday. 2nd and 3rd rounds of pollen harvested yesterday and this morning...they are drying.

VB pods not ripe yet, but getting there.

 

[Tonygreen]

Mind checkin my thread and telling me if you think mine will make pollen? Day 28 nothing yet!

 

[teide]

Very thorough thread.. Nice.
I imagine you will get pollen, seems similar to my results. I get pollen, but no clouds of dust. Easily enough to pollenate, but I've needed to harvest it.

 

[Tonygreen]

Does it come off when you tap branches or pull them off and tap?

 

[TychoMonolyth]

It falls off with just a touch. Unless you take precautions, you'll pollinate the whole plant and others near by.

I suggest you power read this thread.

 

[Tonygreen]

Oh I read it but every experience has been variable so just wondering how pollen dispersal went in his situation with his spray schedule and strength. Lots of examples with poor pollen drop.
I'm at day 28 on mine, hope it pollinates everything ha. No obvious signs of dispersal for me just yet.

 

[teide]

There is definitely pollen, harvesting every day. But I might have been too eager on the dosing, as it seems quite meager so far. I have to scrape and poke a bit with the little collecting card. Non reversed pollen I collect just tapping on the branch. This is nothing like that. I also think I overdid it as the whole plant is all balls. An application on one node would have been enough, then I would've had more female flowers to grow seeds, instead I have maybe a handful of visible pistils on this plant and more balls popping up each day..

 

[teide]

I am also sure that pollen has flown already, even though I seem to be searching for pollen when harvesting. So the technique worked and I am happy, but next time I think I will apply less. Same recipe, but applying maybe just once or twice on just one or two nodes.

 

[weedeasy]

Loads of pollen. Very happy.

How do people find the results outdoors? Does the reversed plant usually mature in time to hit the females? Thanks

Both of you a big GG, very well done!

And now try to make some fem seeds with that pollen.

Please keep us posted of your progress.

What timing works best for autoflowering plants?

I’d really like pollen from any full-autos that show in a photo x auto F2, and realized the odds are much better if everything is hit with STS.

 

[gorilla ganja]

With Autos I like to start spraying when they first show sex. 2-3 weeks from sprout.

 

[zif]

Nice GG, thank you!

Have you ever aimed at partial reversal for selfing with autos?

With photos, I just spray a branch, but thought maybe in autos it would be easier to, say, apply STS just once to get some male flowers mixed in with female flowers.

 

[gorilla ganja]

I have never selfed autos by reversing part of the plant. Although I have a few reversed right now I am tempted to try it with.
I also wonder if the STS will affect the seeds somehow?

I have however selfed autos by taking clones. The cloning process slows down the flowering and allows you to get some pollen from the main plant. The timing is tricky and you don't get many seeds from the clones. But I'm going to play with this more in the future.

I think you would have to spray more than once to get a reversal. With autos you will have plenty of female flowers if you just spray the top of the plant.

Best of luck

Based on one time of experimenting with this, the answer to your question can be yes.


This fall, an entire limb on an OG Kush x Neville's Haze was treated three times, once every six days, shortly after showing its sex in early September. About a month after the first treatment the limb was full of anthers. Some of the anthers had pollen falling out and some needed to be dried and screened. Anthers kept developing until the limb was harvested in early November. The harvested limb was full of s1 seeds. The collected feminized pollen was both stored, frozen in several aliquots, and used to pollinate Malawi x PCK, Panama x PCK, and Congo strains. Many, many seeds were generated.


With that said, the sequence of an outdoor course of STS treatment, induction and development of pollen-filled anthers on female flowers, pollination, and maturation of seeds done on a fast-flowering indica may prove difficult. To allow full ripening of the seed the plant would need to be allowed to grow past its typical flowering period. Weather may or may not facilitate this on any given year.



You can always collect pollen and freeze it so next cycle you have the feminized pollen ready to go when you need to use it.

Chocked full of good info.

Have autoflowering strains been back-crossed enough to get stable high-quality and auto-flowering offspring from them? My impression is that most of the strains out there are hybrids.

I'm sure there are a few, I'm working on some.
If you cross a photo to auto it takes 3-4 generations of inbreeding to get full auto. So there is some inbreeding going on.
But just like photo strains, most are hybrids and far from true-breeding.
