12/12 From Seed: A Different Way To Grow

[PhenoMenal]

Wow, I'm really impressed! Do you start your seedlings under fluorescent, and then swith to the 600 watter, or is it the 600 watter all the way through..?

phrank,

All the plants in my photos above were 12/12 from seed -- no veg at all. I do have a small flower chamber with 2 x 130w CFLs, but rarely use it because taking care of two chambers is a lot more work than just 1, and because I've been getting such excellent results with just the flower chamber anyway.

I like this concept, I might try this when I get my self together. I am considering using a mother and cloning, how much time will this cut down on the time to finish if any at all?

Well, SUBTRACT all the veg time that you otherwise would've vegged for, but then ADD 1-2 weeks to what it normally flowers for. For example, if a strain is listed as being ready in 50 days then its probably going to be ready in more like 60 days if 12/12'd from seed. But altho you gain an extra week or two in that respect you save all that time that you would've vegged (which is usually over a month or two for most people).

It goes without saying that if you veg a plant it will be able to yield more during flower, but people will be very surprised by the good yields they can get off plants 12/12'd from seed.

hello all new poster here been reading the site for about a year, and a regular poster over at riu..let me first say thanks you guys have provided a great deal of information on this style of growing ........I currently have a grow journal going at riu and I am hoping for the best I am working with bag seed, but have grown some stuff i was very pleased with.... my question is what is the most effective way to make seed, keeping in mind I only have one grow area...should I just leave a female in, maybe one that looks like it wont produce much until she seeds? and if so how long does that take ( i know its strain specific) but is it normal flower plus 4 weeks or something???... hope that makes sense I am puffing on some home grown right now....

Okay so I will have to admit I did not look thru this entire thread. Maybe only like 25 pages or so...including the last 5. I have just one thing to say... I'm not convinced. I challenge Hal, Atmosphere, or anyone else who want to pick up the gauntlet to prove this method to me and consequently the rest of the world. I dont post here much but I will check my PM's this week t see if I have any takers. PM me and I will send you my credentials.

There already is proof in this topic I believe

This should tell you something:




Ofcourse there was a lot more involved than just growing 12/12 from the start . There are so many ways of doing that .

Great thread !
I'm giving my very first try at indoor growing and have decided to start straight from 12/12 (using 200W cfl, grown in 1.5liter plastic bottles).
Nutes I use are : BioBloom, BioGrow, TopMax, GHE BioEssentials, Cannazyme and Supervit (That one bottle has disappeared from the nute case ! Maybe the mice took it??? eeeeek !)

Unfortunately my grow space was raided by mice and only 2 plants out of 18 escaped the onslaught. Damn, my growbox (bought after the attack) should be packed with budding babies at this time !
Had to start a new session with:

- RF Burmese
- Yarkhun (Pakistan landrace)
- Yarkhun x Laspur Gold (cross between 2 Pak landrace)
- Yarkhun x Baytik Shan (Cross between Pak and Mongolia landraces),
- Shirin Gol (Tajik landrace)
- Uzbek,
- DC x C99,
- Skunk x BlueSatellite,
- Chizbek (Pakistan Purple Chitral x Uzbek)
- and a sativa (got mixed up with seeds, so I'm not sure, if not Capricho (Colombia x Malani) then it is PNG).

Here one of the 2 survivors, Orient Express, 14 days from first flower.



And a yummy bud of the other survivor, Uzbek landrace.

This is the part I still dont get...can someone explain it too me please ...lets say I have a strain that has a 8 week flowering time, how long am I looking at seed to harvest? I understand there are several factors but assuming everything is as it should be, am I looking at 10 weeks total?

That sounds like a good bet to me...

 

[buzzed day]

done this last time i had to shut down and start over.here's the new one

[bigd21]

That sounds like a good bet to me...

thanks I guess looking at the thrichs is the best way to tel just trying to get an idea

New 12/12 grow (13 strains)

New 12/12 grow (13 strains)

After getting 5 males in a 6 plant grow, I decided to give this method a try, so there is no interference with my only lsd flowering lady. I just planted 13 seeds in one gallon pots with quality soil, 5% perlite and 15% coco coir, all under a 400 w HPS Hortilux. The chosen strains are:

1 Double Strawberry Diesel (Res)
1 South African Durban Poison X Skunk #1 (Sam the Skunkman, Seedbay freebie)
1 Kalichakra (Mandala)
1 Gypsy'a Gum (Somango x Bubblegum, Seedbay freebie)
1 Green Devil (Tiki Seeds)
1 Skunk #1 (Sam the Skunkman, Seedbay freebie)
1 High End (Legends)
1 Red Eyed Bride (Legends)
1 Malawi Gold Mini (Afropips; Afrojim himself recomended this method to me)
1 Senegal Haze (Afropips; idem)
1 Kali Mist (Serious)
1 Mexican Sativa (Seedbay freebie)
1 Chem Haze Diesel (Res)

I will keep you informed.

11 weeks , in my opinion .

When you veg your plants this means a lot of light will be lost because of more open space between the plants (because less plants are probably used when you plan to veg.)

Most efficient is to have your light shining on lots of green as soon as possible . With a larger number of plants this will be the case sooner than with ony a few plants .

Howdy everyone


I have been reading a lot about this 12/12 from seed, all the way back on OG and then "forgot" all about it. Been running with clones and it have worked well, there where alot of debate on this years back and I see there still is some. The difference now is IMO there is alot more proof on the matter today, compared to the few ppl who did it on OG and all the others flameing it.

Anyway I was starting to read about it again, found myself standing with no clones after a power failure that killed everything but my mother plants.

So I took the jump, everyone is doing this in soil but im like a fish. I need to be in water, so venture where few have gone befor me. Atleast I have only seen one or two 12/12 from seed grow's done in hydro, one here but I don't think he finished it ... if so I missed it. Long thread, but tryed to read it all!

I sprouted A LOT of seeds, potted them and put them in my aeroponic flower room. Running 12/12 a week after the seeds where put in RW cubes, so they only broke ground. Alot of seeds did'nt make it for some reason, dunno why and alot of the seedlings did'nt make it for long. Others on the other hand is doing really well and growing strong, so it's not all a failure. But now that im removeing males, it's becomeing smaller and smaller. Turned off some light, moved the plants together as I removed dead plants and males as they pop up.

Seeds where planted the 2nd august, moved into 12/12 the 9th aug after being potted.

They have been 20 days in 12/12 now, they are starting to show sex and I have changed the nutriends to flower nutes.

amazing thread

any strains it doesnt work with ?

I had an afghani once . in the top 3 momst potent plants ive ever worked with

If I flowered it within 4-6 weeks of popping it, it sucked.

If I vegged it over 12 weeks it was BAM

In all other regards than potency it loioked almost identical

I have 1000s of seeds from a far greater collection (i ised to save EVERY seed brick mids exotics everything) so it seems so so attractive to drop a moderate SOG in a eb and flow and do 12/12 from seed to sample the variations in nthe next generations stock without dedication a huge amount of real estate and time

Anyone else do it for that reason ?

great work by the way guy


In order for there to be progress there must be deivation - F.Zappa

I have been interested in this method for some time, for many reason's. I'm not too interested in peep's negative opinion for whatever matter. This is an interesting and exciting topic as it has shown many many positive fact's.

For people who have limited space to peep's wanting a quick crop this is ideal. And also for those wanting to try out a large array of variety's to those who have a ton of seed's.




Anyways, i had to try this out. I had a grow going earlier this year of 3 Papaya clones under a 250W, with space to fill. I germed some Cinnamon seeds from Femaleseeds, and once they popped i transfered to Jiffy peat pellets.

I had 2 good baby's, but one cracked before the other by 5 days. After they showed roots i potted into 1ltr square pots. They were about 2-3 weeks old from germ when entering Flower chamber. **** SO OBVIOUSLY THIS STATES IT WAS NOT A TRUE 12/12 FROM SEED GROW.**** I had read in this thread that it's worth giving the seedling a few days to grow! I allowed for 3 sets of leaves before flowering and the delay because of the stress of repotting.

I DIGRESS

(YES I KNOW THIS IS'NT A 12/12 FROM SEED FACT, JUST MY 2PENCE WORTH!!!!)

I waited 20+days for pistils to show, and flowered for 81/2 weeks. I got 25grams from the slow starter, and 30grams from the first to germ. They did grow tall, but were manageable. The Girls got chopped early as my wife got pissed off with me, and took it out on Mary Jane.

I will say that for Mostly Sativa's the 2 week seedling veg is not nessesarily eccential but did help with yeild (obviously). I do intend to try this again in the future at some point.

Good luck to all believer's, triers, hard up for spacer's and motherf*@r's wanting to try this method. But just to repeat my self, that i had read in this thread that it can be effective to allow at least 7-10 days of growth of the seedling prior to entering 12/12........

Peace Tc

 

[Lava Surfer]

Wifey took it out on Mary jane, hmmm sounds like u need a new wifey cherry mate .....j/K a seperation might be enough.......


Ureap daum 12 weeks vef on a afghani, I did a afghani SCROG I vegged for 8-9 weeks and hey got MASSIVE but a really really slow veggin plant.
