12/12 from seed......

51 posts in this topic

I've never tried but I see people discussing it frequently on other boards. It seems to me you'd end up with a immature plant with reduced potency offsetting the proposed benefits of the method,quick turn around and most of the growth going to the main cola,which is a large percentage of your yeild.

Has anyone here tried it and are my concerns about this method valid?

hi man, well i've tried used this tech for about 1 or 2 years before i stopped my grow, and i think it was my favorite so far, the one that would give me the most yeild in the shortest time and the prfect amount of weed for my personal smoke ^^ but i think this tec is valuable only for "small grows" ( 1m² maybe a very little above) and small lighting system, for people with 1k bulbs etc i don't think it is worth it, but it really was my fav tech, a kind of perpetual harvest where you can put everything you want anytime you want ^^

As far as the immature goes, i don't agree on that some of the most beautiful buds i've made were on those smaller plants as it focuses only on a few buds ( more or less 30 40g per plant under 400w ) and the taste were really never behind the plant that grew for long veg period, same goes for the high i've find it very similar to reg growing and would not be able to make a diference between the 2 i don't think anyone could ^^

for your concerm about all the growth going to the main cola, you can still top your plant if it is the way you prefer plant, it might just take a week more to get back to normal groth and catch the late but it should be worth it if you like bushes :) I've made almost pur sativas and pure indicas grow together ( and by the way 12/12 from seed for sativa is a delight ^^ ) and with care and atention and if you manage your canopy you can do anything and harvest every 70 to 90 days, or longer depends the strain ^^

Lol sorry for the book i think you understood i find it valuable ^^ not for all grow ops, but for most private growers i find it awesome ^^

Good luck try it and see by yourself ;)

I don't mind the book, your post told me exactly what I wanted to know. Sound like it would be perfect for a cabinet SOG and a cheap way for people to grow their own personal meds.

The guy who first told me about it used it for growing sativas indoors. However,there was bit of a language barrier and I never got an answer to many of my questions,especially ones on potency.

Highly potent S.E. Asian Sativas indoors, without having to worry about frost,cops and thieves you have to deal with outdoors. Hmmmmm............. Where's my toolbox?

haha MODE: Mc Gyver ON :rabbi: :rabbi:

More seriously yes for sativas it is a very nice tec, i've some Arjan ultra Haze etc under this tec, and they LOVED it probably one of the biggest yeilder under this regiment, but well was the longer too so it makes sense ^^ good luck man

I am making my first attempt on 12/12 from seed with some autolflower Kalashnikova and am very happy so far, looking good and saving me money, they also smell equally potent as the AK-47 i grew a while back. I also like the idea that you can add extra plants when you like and this adds variety as I plan to do 2 plants every 4 weeks when i start indoors to get a regular supply of many strains.

My last crop was a 12/12 from seed crop and I harvested around 120 days. I think at 121? But of the 5 plants I harvested, I'd say I averaged 1 1/2 ounce per plant, but I got 1oz from one of those plants, and nearly 3oz from another. The other three were around 1 1/2-2 ounces!

All in all I was VERY pleased w/ 12/12 from seed and will do it again! Once I flip this crop to flower, I'll start a next generation on 12/12 from seed!

Last run I vegged for maybe 5 weeks with a first crop and started 5 12/12 from seed when I flipped, and I ended up harvesting those about a month and a half later than the initial crop, so it was very nice!

Also they reason the plants took 120 days rather than 90/100 is because I topped and trained them!

But I could literally quote Dust about word for word here! You can't go wrong with 12/12 from seed!

The potency isn't reduced at all, only your yield. Plants are def. no immature either. More like premature haha!

Sounds good. All I'm looking for is a continual harvest system that can give me a couple of ounces of bud a month for my own use.

The 12/12 method always intrigued me but I could never get straight answers on the potency issue. You guys have been a big help,thanks!

What is the temperature in Kelvin(6500 or 2700) should be during vegetative growth and flowering under this technique ?

I do just like with a regular cycle personally, start in veg with the blue spectrum, i keep it the 2 forst weeks of flowering more or less, then switch to the redder spectrum, if you can keep the blue and just add the Red in extra, even better ;)

 

Have a good grow

potency is matter of mostly genetics and perfect harvest window

 

maturity is matter of observing trichomes nothing to do with length of vegetative period

 

Yield will be affected, I use this method because I am not a heavy smoker and I like multi-strain grows that include all 3 : sativas, indicas and hybrids. 

 

Pots I would suggest 10-20 l but you can get away even with noodle cup with this method but smaller pot = smaller yield. Anything beyond 20 l is most likely overkill since plant will not have time to root it properly. 

 

I am attaching table (I'm not the author it's from different forum) that should clear your mind. 

 

Remember plants are not sexually mature before 20-30 days of their lives, so you can give them 16/8 light cycle for 3-4 weeks and you will have slightly bigger plant and yield then actually starting 12/12 but it will not slow down anything you will still reach harvest extremely fast comparing to other methods that usually veg for like 8 weeks etc. 

 

After trying both 12/12 from seed and 8 weeks vegging I am going back to 12/12 way too much weed and more time wasted, unless you are snoop dog and smoke more then an ounce a day 12/12 is the way to go with small personal grows. Especially that weed is like wine to me, I prefer to have 10 bottles each different wine tasting different then 200 bottles, all filled with same wine that I can't drink through  with my glass on weekend.   Currently I got 5 jars with 4 different strains (1-2 ounces each) and I plan to have 12 different strains after next grow.

. Good news bro , I am about to start a 12\12 from seed grow with 12 strains in 11 litre pots

I'm going 8 strains in 6.5 l pots this time :D previously I had 15 l pots and 3 strains at the time. I assume I won't smoke through my stash till grow ends and I have 4 strains there currently so I will have 12 :D 8 plants 12/12 grow I hope for around ounce per plant. That should be more then enough for me, from first 2 grows I had total of 8 ounces and that last me year and I am not even halfway! I only have 300W LED but again it is more then enough for me. I think 600-800W would give more optimal yields.

What should be the minimal requirement for the pots using this method?

 

 

 

Yeah i dont think there is a minimum size of pots for this tech, the optima is around 7L and 11l max for me, bigger i dont see the use in 12/12 from seeds unless maybe for a very long sativa, and even there an 11L should be enough.

 

Good luck ;)

I started 5 Exodus Cheese + 4 Chemdog about 3 weeks ago (1 seed was crushed,that's why it is 4 not 5 Chemdogs). As usual my method is watering the seeds/growing a tiny rootlet then planting them into 2 litre pots under a 18 WATT Neon light. Since the neon bulb is only 60 cm long I could not keep all 9 under the light for more than 10 days or so and growing them with a 125 watts ESL Grow Ligh18/6 t did not give any beneficial results. So I split the 2 strains up. Put those 5 EX Cheese for 18 hours back under the 18 watts NEON and placed the 4 Chemdogs in the tent along with the Damnesia in flowering stage  ca 60 m distance from a 400 watt HPS- 12/12. The results speak for themselves - These Chemdogs are easily twice as tall as the Cheese and showing 5 fingered leaves already while the por EX Cheese look really poor Was high time to do something about it. Now they all sit in there till the Damnesia is ready .. (end of the month) then I got the next weed 2 months latrer hopefully. 

I still recommend changing to longer VEG every fourth grow, otherwise ithe results are getting lower and lower each time  you cabnnot rusnature..

It depends gravely on the plants genetics if it works at all resp. giving you a high qualitity yield. Strain has to be extrmely stabilised otherwise you get a field of salad mixed with asparagus ;-)) F 8 or better

 

I tried it twice on 2 m² and only tthe santa Maria was stable enough to produce more or less 70 or so same plants with good quality. But it is an easy way to test a strains stability.

It is anyway a tricky and complicated grow because of the weakness in the root system of the plants. That results of the immediate 12/12 flower period and the plnats can not develop a good root syetem.

 

So: I for myself gave it up. I felt if I had to cough one time near the plants next day they are yellow or so....

Not a fan of it..

Dont get me wrong with most Strains it works fine, yet i hold my Hand in to the Fire that ill produce better Yields over all and more Resin if i let the Plant reach maturity before i send her on a 12/12 cycle.

In my Eyes its like Dust said if you got a small closet and want to get as many yields as possible not really going for the big yields its a viable option.

Tho one day you will encounter a Strain that plain out goes full retard on you with this Tec, and this will be a sissystrain like Dr.Greenthumbs or a Trainwreck even ;)

cheers

I'm no expert on this technique , but surely the plant won't flower until it is mature enougth ?

funny you say it stresses as im seeing the total opposite every time, it reduces the stress factors given you dont make other changes all the time

 

 i find the 12/12 from seed plants look extremely healthy every single time as it is always in steady enviroment. the plants vegged in 18+h different light spectrums and suddenly flipped to 12h with out gradul drop will def have more stresses and adjusting than one with constant hours that never had to adjust, that is given

 

i have never seen any thing weird happening to any plant from it or stress herming due to it ive seen grower errors tho when using it and they like to blame the light.... like way too much nitrogen and other nute problems, easy to blame 12/12 for own mistake:D

Using 12/12 I start 18/6 till 3-4 weeks till plant is sexually mature. It is still 12/12 from seed method because you switch to flower cycle asap. Only time I would go 12/12 literally from seed is when I have extremely limited space like growing in PC case etc. 12/12 from seed is literally reaching harvest goal with absolute no veg period longer then necessary, not starting 12/12 from day one. People get that confused a lot. If you think about it, which plant will finish faster? One that you started 12/12 from day 1 or at week 3 when they are sexually mature? Well exactly the same but second will be slightly bigger and will yield slightly more. 

As for yield it was already discussed but I never heard about resin production being affected by it. And what do you mean by plant going full retard? Not exactly precise expression.

yes it seems that many people are getting confused about the plants maturing time from seed to adult that doesnt have anything to do with flowering. the time varies a lot from strain to strain, some early flowering strains can start as early as day 21 from germing that evolved in colder climates with short summers and some equatorial varietys might take 60days from seed to start flowering and they get 12/12~ light cycle outdoor whole year, the common hybrids we all grow are usually adults in 30-35days from germing

 

you can not force the plant from seed to start any sooner by flipping to 12/12 the amount of time it needs is fixed by the genes not by us, like leyous said both plants are adults when they are adults no ifs or buts about it, no matter if one spend 35days of veg in 18/6 and the other in 12/12 both still vegged same amount of days and both are adults

 

how ever you can force any adult plant in to flower when ever you want to, even the tiniest clone, when the plant is adult they start growing preflowers on the main stem and the nodes start to grow asymmetrically no matter what light cycle it had in the veg phase

Maybe there is a confusion. When 12/12 is mentioned, it is 12/12 from day one. When you have some 18/6 in the beginning it is NO 12/12, right.....

 

So 12/12 menasn the plant get not more light than 12 hours a day from the seed.

I'm sorry but you are wrong. 12/12 from seed method doesn't mean plants get only 12/12 cycle. Here have a read:

http://www.growweedeasy.com/12-12-from-seed-force-flower

You shouldn't express your opinions on methods you don't know, and unless you were trying to limit your plant size extremely (then yes start 12/12 from day 1) you should wait for sexual maturity. So you have done 12/12 from seed wrong mate that is why you didn't see decent results. 

 

This method assumes eliminating vegetative phase, not restricting light to your plant before it reached sexual maturity, especially that most of this phase is seedling phase which you shouldn't mess with.

 

Also for most of plants we grow indoor, 12/12 is way more natural method then this ridiculously long vegetative periods. In nature only some sativa strains get that.

Strain Hunters is a series of documentaries aimed at informing the general public about the quest for the preservation of the cannabis plant in the form of particularly vulnerable landraces originating in the poorest areas of the planet.

Cannabis, one of the most ancient plants known to man, used in every civilisation all over the world for medicinal and recreational purposes, is facing a very real threat of extinction. One day these plants could be helpful in developing better medications for the sick and the suffering. We feel it is our duty to preserve as many cannabis landraces in our genetic database, and by breeding them into other well-studied medicinal strains for the sole purpose of scientific research.
