Light poisoning to make seeds

[yesum]

Has anyone done this to make seeds from a female plant by making it hermie? I am wondering how reliable it would be compared to spraying silver on a plant. Something I would rather not do. Can not smoke the sprayed plant.

I guess interrupting the flowering darkness with 1 hour of light each day would be enough. Just wondering how often it would work to make the plant hermie and produce seeds.

Just turn your light on at random times and take pix , should find some seeds ,I've used this trick. I bought some spray now I have 10,000 seeds lol

Possibly an hour of light at night on a consistent schedule would cause the plant to just veg and not herm. Maybe a "random" schedule would indeed be better.

That said, I have had a plant that was stable on 12/12 herm on just a 10/14 schedule - no light at night. Didn't use the pollen. This is a failed stress test not a pollen creation method IMO. Though I do see the value of not having to use any chemicals.

A famous method is Soma's "rodelization" where he suggests to let plants go very long in the hopes of them throwing out some late nanners. Also in the failed stress test category IMO.

Why would anyone want hermie seeds?

 

[yesum]

Forced hermie seeds are not the same as naturally occurring. Same as spraying really.

 

[shawkmon]

Yea they are femmed not shermies, uggg rookies

I can tell you first hand Somas method dose not work.

If you love the genetics and enjoy them my advice is find a nice male to make seeds with.

 

[yesum]

No nice males to be had, these are fems. Not gonna do the overripe thing as I like my smoke on the early side.

I recently tried this on a Jarilla. I did multiple darkness interruptions,but have not seen any evidence of success. (but my eyesight is not that good even with a magnifying glass )

I'm old,and figured why not try it and see? I'd really like some Femmed Jarilla anyway.

In my opinion their exist a few 'bad' feminising techniques.
Light stress is one of them.

But there are more bad techniques like N Toxicity, root pruning, temperature torture and Rodelization as goinggrey posted and several more techniques.

All these 'bad' techniques rely on the fact that a 'female' plant can go Hermie when it endures stress. You don't want these stress prone plants to feminize with which go Hermie. You want strong 'True females'.

Other techniques like STS and CS rely on the fact that the growth hormone Ethylene gets blocked hence causing the expression of male flowers. These are not stress techniques and are the techniques preferably used in a feminization process.

(But please don't hate on me. This is my opinion about the different techniques.)

 

[DoubleTripleOG]

In my experience you aren't gonna cause a plant to go intersex by turning the lights on intermittently during the dark period. Unless you have really unstable genetics. Only time I've ever had a plant go intersex that normally wouldn't. Was when there was a light leak. And a portion of the plant received light 24/7.

If it was me. I would bring the whole plant out of the dark and into a lite room. Leave it there for a couple hours , then repeat that process at least 2x during the dark period. Also thru experience I've noticed if plants are gonna go interex, like full on tranny. That usually happens in the first 3-4 weeks of flower. If I was trying to make intersex traits, that's when I'd be abusing my plants.

I agree with @Cvh - we should difference between feminisation and 'natural' ways of reproduction.
There is also a thesis that seeds from fems hermies tend to herm too. My opinion is that this cannot be, genetically. As the male chromosome was removed you should expect only females.

 

[goingrey]

There's only a difference if the STS/CS reversed pollen donor is thoroughly stress tested and vetted beforehand.

If the pollen donor is something that will herm from stress, I'm sure that the hermie pollen is just as good as the silver-induced pollen.

Ok so don't use them in breeding at all? As the pollen donor or the mother. Well, sometimes the slightly sensitive plants are just so good that it's worth it. Think ECSD or something like that. But if you want to do it right, work the line some generations with big plant counts and breed out the hermie tendency. Easier said than done though.

 

[Snipp]

I do not breed ( intentionally). But if, I would not use such tendencies for reproducing, but more try to get them out. This would be serious breeding.

But for just growing weed I would say you can use hermseeds without a bigger rate of herms

CVH covered it. If you don't like harsh chemicals, go to a health food store, get some c.s. and boil off some of the water. You can get it strong enough to work that way.

I really do not care if I have a hermie prone female or not, would prefer not but either way. Just grow them alone by themselves if needed.

Did not know the CS method was a bit different in not selecting for hermie prone plants. From Slim and a lack of anyone actually telling me they tried it, I am reluctant to even try it myself. Like I said, hermies are part of landraces and not something I fear. This would be a landrace strain even though it is a fem, I know confusing.

Light poisoning is a very poor method of creating seeds you would want. I strongly recommend STS as it works amazingly well. There's a tutorial pinned here on icmag with a ton of great info and success stories.

Reversing hermi genetics will still have hermie plants from the femmed seeds. I STRONGLY recommend only reversing stable plants which are near impossible to reverse without silver. The only time I would consider reversing hermie plants would be to grow out tons of the seeds and stress test for hermies. The goal would be to find non-hermie versions of the original to breed with.

Not sure what people are referring to as 'harsh chemicals,' since sodium thiosulfate is listed as one of the safest to use medicines on the planet. The silver nitrate can cause issues with strong exposure, but STS solution for reversing plants is ridiculously easy to use safely. You can all put away any fears of STS being somehow 'bad' for cannabis plants or humans when used properly.

Orally ingesting nano silver is perfectly healthy.

Silver in it's nano, aka monoatomic, aka nascent, form will be absorbed and used cellularly by the plant. Silver also kills harmful bacteria, virus, and fungi/mold. Why hesitation for Silver?

 

[yesum]

^^ I thought I made that clear, I want to smoke the plant I get seeds from. I may not get but a couple seeds.

A lot of hermiephobes here. Just kidding. I have some Laos landrace strains and they hermie, just part of things. Take the male bits off the females as you see them to cut down on the seeds being made.

Thanks for all the info everyone. Not sure if I will try this or not. I grow for myself and am used to females making seeds by themselves due to raw or landrace genetics. Not the end of the world. I wonder what has been lost there by making that trait go away, the landrace stuff is not generally as good as it was back when this was not done.

I want to be very clear that your fears of using nanosilver and then smoking the plant later are unfounded.
