If all I want is seeds, go 12-12 from seed?

I'm sure this question has been asked, but searching provides a bunch of unspecific results.

I am thinking about producing fem seeds using the colloidal silver method. If all I want to do is a quick seed run, can I go 12-12 from seed, or should I veg a couple of weeks? Not interested in any smokeable bud production from these plants.

Any info or suggestions are appreciated.

Thanks.

As far as I know when you plan on making seeds it's better to let the plant mature a bit before you throw it into flower.

Sounds good too me, why not. From the 12-12 from seed I tried, you don't get hair's 2 week's from germ. They still take 4-6 week's to mature enough anyway's. IMO. I'm going to try it like that when I go for it as well. Don't forget that 2 week's before flowering thing with the silver.

My thought is to start the soon-to-be male/hermie 2 weeks before what will be the seed mom. I have heard the silver treatment can stunt them for a bit. Does this sound practical?

Also, I'm sure I can look it up, but when do you start the silver treatment? <---- I looked this up. Sounds like you start treating when pre-flowers show. Is this correct?

Ok from what I read up on and some body chime in and correct me if I'm wrong please, that you start with your spray a couple week's before you start flowering. If you were going to veg for 1 month I would start about week's 2.5 - 3 till you could till that it worked. I'm going to grow out a feminized seed and take a clone from it. Then I'll take the clone, and spray one branch on it to get it to turn. Let that clone grow out to pollenate it's self. Hopefully the whole plant end's up seeded, and I get plenty of femmed seed's for my end of the world weed apocalypse scenario.

Right on. I start no later then a week B4 flowering. One being because it takes a good while for a feminized seed to produce/show male pollen. I have some even take longer - 2 to 3 weeks. They also react in a way to being sprayed with CS. Some wilt and look as if they are going to die (branch sprayed), and or may even change color.

You do know that the "hermie trait" will be passed on to the future cross/strain correct just checking..

I guess I'm not following. A hermie trait from a plant that didn't hermie? I seriously don't know.

Whether a feminized plant is more likely to hermie is one of the hotly debated subjects amongst growers. I don't have the answer but I would guess that a plant stressed (via light, nutes, etc) into herming would have a greater chance of herming than a plant that CS was used on. That is not to say that a CS induced plant has the same chance of herming as a regular seed though. I tend to trust Dankster's opinion, he is an experienced breeder.

I am doing a feminized seed run right now for the first time using CS. I started spraying 1 week before flower and started the CS plants into 12/12 a week ahead of the other plants. The timing worked fine, just make sure your PPM of CS is high enough otherwise it will take forever to reverse them. Over 40PPM is good.

I did go 12/12 "almost from seed", they had about 10-12 days veg time. I expect I will have more than enough seeds so I don't see a problem with 12/12 from seed.

I always do it, it works great. as long as you wait a full 35+days after pollination, you will get nice mature seeds. Personally, I dont think it affects the genetic in any way, the plant has it's own dna, it has the same dna all of her life unless she is heavily stressed out so essentially you are still crossing DNA1 X DNA2 whether you vegged for 12 weeks or 0 weeks, the end results should be the same. I have been breeding with strain that do well 12/12 from seeds so now any of my strains can be easily grown 12/12 from seed as well.

As the previous poster pointed out, it's not genetic manipulation. The ability/chance/likelihood it turns hermie under the same circumstances is passed on. Ideally you stress-test the females and then spray the females that didn't turn easily by stress, preferably not at all. You can pass on nature, not nurture, it's as simple as that.

As for the original question, if you go 12/12 from seed it will still mature first before flowering. I would also want to know what the plant looks like in veg before making seeds with it.

Very good points being made. Thanks. This is still just a "thought" in progress. I'm leaning more towards vegging for 2 weeks before the flip.

Mr. GreenSanta, your all over it.... Same here Man
Hey let me ask you please.... How do you store your seeds if you ever do ? thanks

I have been keeping them in a drawer but some of them are 2 years old and I hope to keep them around so I might go buy a pill tray from the drugstore and store all my seeds in the freezer. I have to do more research to make sure the freezer is the way to go... but I usually endup making seeds often enough that I have not been growing older seeds for a while now. I have some nice (Ancient OG male X (Chemo X Respect)) coming up as well as some F2s of the Chemo X Respect. I also recently harvested Pennywise X Senora Ampero so yeah, going for CBD right now ...

veg for at least a month!!! in an ideal situation you would sex the plants before you flip

to produce more mature seeds the females should start flowering at least 2 weeks before males for indicas and as much as 6 weeks before males for sativas

Great point on the lead time, especially for sativas. I gave my hybrids 1 week head start and it has turned out fine but the couple bag seeds turned out very sativa dominant and they are proving hard to pollinate and if it does take not many seeds will result.

It's true, I haven't been able to force flowering before 30 days in my experience.
When I breed a fem I light it 24 hours for 3 weeks, the male I just leave outside from germination.

I will just say that the PPM of any CS is key to the timing of pollen developing on time. Run it at 27 volts for 24 hours and you won't have a problem starting the CS "males" on 12/12 a week to 10 days ahead of the standard females.

Just make sure you spray them twice a day with CS for the first week at least...

If they are pure sativas then I can't comment, other than saying give them at least another 10 days or so of a head start over what would be required otherwise (by hybrids/indicas). The sativas I am trying to pollinate with the week+ head start I gave them are not going to produce much seed.
