What is the minimum time I need to veg. for before the plant is mature enough to put into 12/12 ?.
i've seen peeps go 24/7 for ten days, then flip to flower...
from seed, there is no way the plant is any way near ready for flowering 10 days from seed, and the 24/7 light schedual doesnt mean ur growing faster either. i would give a plants atleeast 25-30 days from seed they should be mature enough to flower, aswell as they should be able to hold a high ppm with out burning. 10 days thats like not even a plant yet.
Thanks Wack. I sorta thought 4-6 weeks myself, or until there are 4 internodal spaces. I'm growing out 50 seeds in the hope of locating a good mother. I'm going to sprout the seeds, put them in rockwool, and begin growing them in flats until the roots burst through. They then go into my aero system, I'll veg. them for 2 weeks or so (assuming 2 weeks in the flats) and put them onto 12/12
well if your looking for a mother i would suggest finding some of the best ones that are vegging take clones at one month and then after they root, flower a couple of them to see sex, and then once u find femals the other clones still vegging will be nice and big ready to fully flower. and then u can pick your femal mother who is still vegging and it works out pretyy good. Just make sure u know which clones go with which vegging plant so u can determine sex and good genatics for a great mommy.
You can go straight to 12/12. There is a thread going on on icmag about it. People get around 1 - 1.5 oz using that method. The plant is going to grow and mature before it flowers regardless of the light cycle.
Personally I would just go 18/6 for a short time then flip them to 12/12 but you can flower from the get-go if you want to.
People growing sativas indoors can go 12/12 from the beginning as well to keep height and total time till harvest down.
4 nodes.. from seed.. that is usually 12-16 days for a healthy plant..
and NOW you KNOWM
I've been growing for longer than I care to remember and this is the first time I have heard that seedlings can be put on 12/12 and they will continue growing and once they are sexually mature they will automatically start to flower ?
Do I understand you correctly canuck ? O.K., so lets say I put week-old seedlings into 12/12. How long (on average) will they continue veg. growing before they are sexually mature and start to flower ? OR does the flowering response commence immediately once under 12/12 ?
Ok houdini I haven't done it myself so I'll refer you to where I read about it: 12/12 FROM SEED WORKS! That NL plant yielded 46g. Relevant posts: #11, 12, 22, 23, 25, probably others but I don't want to read it all again :).
What I got out of that thread is that they will grow under 12/12 until mature and then begin to flower when they are ready. Like I said I don't know if I'd ever try it myself, and G.Knowm's post confirmed my suspicions that 12/12 from seed isn't going to be better than a short seedling/veg cycle and then flipping them after they have several nodes.
:jointsmile:
to be completely honest with you, find a journal or somthing on this, dont go around saying this works becuase one kid did it, and posted one picture of a little plant, i can def say that your plant doesnt flower until it is matured and sexed, and well that takes times in the veg stage and in the flower stage who is to say it will even happen because now your forcing it to do something it really doesnt want to do. i mean u say they grow under 12/12 until there mature, u might as well put them under 20/4 until they mature and have full size plants when u flower instead of little runts, it probably takes longer for them to mature in 12/12. seems like a ppl "think" this works but in reality, u get alot less, in the same time.
It's called the Sea of Green (SOG) method and is used for rapid harvests with high plant density. When you flip the plants into 12/12 (usually about 7-14 days old) they shoot off in a huge amount of growth. Internode spacing is pretty stretched, but your plant grows at an insanely fast rate and then flower when ready. If you want a quick harvest and you're willing to sacrifice some yield, then it's probably a good way to go.
This method can also be combined with a Screen of Green grow, allowing you to fill up your screens quickly due to the rapid growth of your plants.
can we get some one in here who actually has done this... i think im gonna try this just to see the results, i dont see a 7-14 day old seedling sprouting up anywhere more then half what it would ussually. It just doesnt logically make sense, and if you sacrafice half the yeild in half the time then it really means nothing. Or half the yeld in a third of the time is even worse. So u get a seedling at 7 days old that like what 2 sets of leaves at best, switch to 12/12 now the plant is going to grow, but not flower due to its immaturity. So it will double or tripple in size giving u about 6-8 sets of leaves which is small, now ur plants starts to flower but it doesnt get that boost because well u already used your NOS when u switched to 12/12. So you plant continues to flower. and 2 months later u have half the yeild margin. Now if you had vegged for a month, which is the time it probably takes to get your seedling to mature and flower under 12/12, u get sooo much more.... really is cutting back a week or 2 worth loosing your yeild. the time it takes your plant to fully flower is probably the same if you vegg for a month.
hehe, i have started turmoil... ok, you want an example? i'll be the example, i'm putting a 10 day old beanling in the flower room tonite.
i'll write a thread, and post a link here.

ps, the plants on icmag began flowering in two to three weeks from seed (sexed positively) if i recall correctly...
good news, i got no beans right now, im glad some one took the initiative.Quote:

The plant grew 6 X's its HEIGHT after switching to the flowering cycle (12/12)... It grew from 4 inches tall to 24 inches tall in 20 days (after switch to 12/12).
cheers
Mountainman, are you the same guy who allowed CC into yr. grow and they wrote an article on it, maybe 3 or 4 years ago ? Let me know, man. I have a question on air scrubbers for you.
Folks, the reason I started the thread was a) Because I had heard half-assed roumers that seedlings could be switched to 12/12, however it would seem from the posts here that the plant continues to grow in a manic vegetative way for a period of time, before flowering. And b) because I want to make new mothers from seed so I intend sprouting loads of seeds and growing them out. I'm not interested in yield, simply having enough to make a judgement on its quality.
I have always waited 4-5 weeks from seed before flowering, or until the plants reached their 5th-6th. internode and I could sex them.
So whats it to be ? Wack thinks I should do it like I've always done it; Mountainman says its possible.....BTW mountainman, When you flipped those seedlings to 12/12 and they started growing like crazy, how long was it before you saw the flowering response ?.
I am here to the rescue, Jack da wack.
Lets say you are growing a Northern Light. You know that you are gonna wanna harvest after ~60 days or 8.5 weeks. You grow your cute little seedling 15 days from the time it pops out of the soil(not even from seed). Then you flip to 12/12. Do you really expect to harvest ANYTHING in 8.5 weeks? Well you shouldn't. Its going to take at least another 2-3 weeks before it even STARTS showing sex.
As you see in my sig, I have 12 females. I flipped them to 12/12 at day 30 from seed. They were a little young at the time. Not sexually mature. They didn't start showing flower for another 2 weeks. After 3.5 weeks i finally got all the males out. While I have had them in flower for nearly 6weeks, they are just beginning to thicken up, and are at the stage where they have no smell, but buds are fattening up.
Obviously different strains mature faster than others, but you are smoking crack if you think you can veg for 15 days and harvest 8.5 weeks later. Yes, you can flower it at day 15, but don't expect a mature harvest for another 10-12 weeks.
My new magic number is 36 days for veg. I think its minimum.
it does lengthen flowering time as they are not mature but you can start 12/12 from seed if you wanted to, there really isnt an advantage to it that I see atleast indoors, if your outdoors near the equator guess you dont have much choice except to just use long flowering sativas if you want large plants,indoors they will be slightly smaller versus vegging for say 3-4 weeks but not a huge difference unless you are vegging for a longer period of time.
yeah, my point was strickly the fact that it has no advantages and probably isnt going to work out in favor. I really see it just taking the same time with less results. yeah veg is half but flowering is gonna take longer, and not be as much with smaller plants. vegging is when the plant determines its size, you can get a pretty good figure as to how big they will get in flower.
Here's someone on c.com who grew 12/12 from seed: http://boards.cannabis.com/indoor-gr...-confused.html
though I'm not sure if they did that purposefully or not since they're new.
eh, u cant really get an understand of what they look like, maybe some more detailed pics, they still look underdeveloved aside from the first pic which looks pretty good. we need to look at them as a whole. and what stage they are in, they could be very well 3 months from seed.
Yeah, probably not grown to the full potential but this is just about what is possible. Well, at least that's how I am looking at it. What is possible, not best practices. :jointsmile:
All in all, we have learned once again, Patience is a Virtue...What's two more weeks really???? :jointsmile: Bree
Yeah, 2 weeks longer with half the yeild
? Why would he get half the yield by vegging longer...did I miss something?Quote:

that's how it ends up quicker, and the yeild is supposed to be quite competitive with a 40day veg time, btw.
and this is all based on someone else's experience, not mine

Unless you have great airflow.. great lighting, great spacing, great NUTRIENT program.. all working to accomodate LARGE plants.. then it is a waste to grow plants over 12 inches before you flower them...
a 1000 watt bulb over 6-10 plants that are flowered at 12 inches tall (10+ nodes) will produce the same amount of BUD as plants flowered at 24 inches tall under identical GROW conditions..
the 24 inch plants will take longer to grow, require more nutrients and make a huge gangly MESS...
iloveyou
and if the 24 inch plants do produce more weight, it will be minimal and it will consist of small popcorn buds... the time you save (wth the 12 inch plants) by starting your next harvest will far out way and minimal gain you get from the 24 inch plants.
iloveyou
I agree with GK. But sky, a plant grown for 40 days in veg, has already been mature and the switch in lights after 2 weeks will or should show sex yes. however a plant that is set to flower after 1-2 weeks is not mature and has to gain a muturity level before it can start to flower, it needs to build up its harmones and chemicals before it can produce bud, 40 days is alittle long to me for vegging i keep it 25-30 days, but due to the immaturity of the plant it may take a month just for the plant to sex. giving it an extra week or 2 in vegg seems more benificial, let it mature and when u swith to flower it is fully ready to go. honestly any one can do this, if you really think you can get good results show us and i will shut up
