The 12-12 From Seed Thread

[Star Dog]

That's 3 weeks today since I flipped, all 4 are showing their sex today, i was sure yesterday at least two were males today it's confirmed along with another 2 so 4 out 4 male

 

[Duhh]

biggest was from a bubblebomb, was around 3 1/4 oz dry, they get big quicker than anything else ive grown. really need to keep the breed alive.

Hi dell what an incredible thread, just wondering if you're still around?

Have you, or anyone else, ever done white widow 12/12 from seed? If so what were the results like?

Thank you!

im perpetual so yes you will get to see some start to finish, ive got more grapefruit, northern lights, bubblebomb,lemon skunk and royal hash coming up, the last i cropped was an orange bud, finished within 11 weeks, its first flowers showed at 2 1/2 weeks old and gave me 2 oz dry.......

I am curious, what are the benefits of this?
11 weeks for 2 oz dry is a low yield. I have been getting 14 to 20 per plant going around 16 to 18 weeks total-
Are you limited in headspace or do you prefer the smaller runs? The plants look good but it doesn’t seem natural for a photo.to have zero veg time. Flowers starting in 2 1/2 weeks so you are in flower around 8 1/2 weeks it seems you are just eliminating veg phase at the cost of yield. So what are the benefits?

Day 44 since pop. Probs Gunna stick with the schedule from birth 12/12 and continue to grow the sativa you see in the right (have a thousand or so seeds here). The chemdog didn't take to well to 12/12 from birth as it basically had no stretch period. The Nepalese pre flowered before the chemdog and is still stretching.

The day i flipped.

Around 30 days later.

5-6 weeks later.

Some of them are quite bulky all considered.

They're looking nice!

Eta... The seedling ones are Swiss skunk x2, og kush and star doggie.

To try and stem stretching the plants I flipped early were left in 1ltr pots until sexed and/or past the worst of the stretch, i then re potted them to 5ltr pots and done some selective defoliating afterwards.

Today they're all 19-21" with the exception of one at 26" but was untouched.
View attachment 5211968 jfc I'm measuring the plant height from the rim of the pot.

It's sister was vegged for a couple of weeks more than the above and with some defoliating it's 20"

I've harvested these two plants, one plant gave me 62g that was the older of the two, #2 the seedling gave me 108g, with less vegging it yeilded more but that's seeds for you.

 

[VincenzioVonHook]

49 days from birth, 12/12 from day one. The sativa on the right took well to a 12/12 cycle for birth and took around 6 weeks to go from birth to end of stretch. The chemdog initiated pre flower after the Nepali and finished stretch within a week or so. Completely different pre flower cycles.

Still on tap water so far, will be interesting to see if I can get another run done with no supplemental feeding.

One of the 4 flipped at seedling yeilded 283g

I don't think I've ever had that much from a typical 4/5 week veg before flipping.

The others 2 Swiss skunk yeilded 173g 124g, the star doggie 146g

That plant was from 12 on 12 off from start?

Hey bud, no, not from the off, iirc they were around 2 weeks vegged?

It's one of the 4 seedlings.

 

[Star Dog]

I done another from 2/3wk seedling soon after the crop above.
Day #1 flipped and re potted same day

.

I wish I'd learned it years ago.

Just wanted to say that I'm happy this thread has come back to life. Kudo's to you all.

@Hot Diggity Sog thank you for commenting it's worth updating if I know people are watching it.

On that note...
I've started another,
I've only recently re potted these after 30 days 12-12.

The day i flipped

I kepr them in root pouches for the 30 days 12-12 then re pot them on Sunday to 5ltr airpots.

The day I re potted them.

Into 5 ltr airpots


that's it up to date I'll keep it posted.

I remember a guy back in early 2000s who did 12/12 with cfls. Had his own seedbank but I can't remember his name. Anyways, I'm glad to see this thread. Brings back memories and it is an effective method many scorn. Till they try it..lol.

Ain't that the truth bro, when I heard about starting seeds in 12-12 I was dubious tbh, now I'm so pleased I tried it,
it's Gold!

Well I'm definitely following along. I too was a skeptic but I know it works for a continuous harvest. I like your version of seedling to flower. That appears to be a little better. I have seed I want to work through and doing this I can a lot quicker. If I find one exceptional I can always take a clone.

This thread has changed my whole approach to fems and regs. I know this works. So I'll use it next round. I'm excited....I'm glad to have run into this. Sure does bring back memories.

A couple of things ive been thinking about.

There's a 3/4 week veg period from 12-12 then there's the stretch phase.
It seems logical that say 2/3 of the veg weeks would be best spent in 18/24hrs light?
Thats namely if you want a big/bigger plant.

I kept them in small root pouches until around 30 days, the idea was to limit the root ball size and in turn hopefully limit the ability to grow too big.
Again if you wanted a big/bigger mother it seems logical that starting in a bigger pot would be better?

I'm sure there's room for improvement but I don't have space to do the testing for bigger plants.

Feel free to grab a trowel and a large pot

@greenmobster440 hey bud, this thread also completely changed my approach, since trying it I've never stopped with the method.

A few other pics grown 12-12 from seedling.
