12-12 from Start to Finish

I KNow it wont fucking flower right AWAY.... i just meant the cycle 12/12 is flowering so technically the plant is FLOWERING!

it isnt flowering til there are flowers starting aka hairs so it technically isn't flowering til then if you don't have a microscope and want to harvest premature its a great way to calculate flowering time though

yea, starting it on twelve twelve from its first set of leaves you could figure out a lot about flowering times on different strains, you could let it run all the way to maturity and still save time cause you cut down on vegging


that is pretty funny you read it at the same time that email came in heh.


i'd love to see someone start a grow and document it. i cant do anything cause i have a trip coming up next month but i'll sure comment on it.

imo, and from experience, 12/12 from seed is not a great idea. the plant does not start to bud when it first sprouts, it isnt old enough or ready. it would be like a baby being born and saying "lets fuck so i can reproduce". it will start to flower at about the 3rd -5th node, so bout two(+/-) weeks. meaning that if you count the days flowering from the first sprout, you will harvest about two weeks early. well rooted clones, on the other hand, are cuttings off of a matured plant, so as soon as they have rooted well, you can throw em under 12 and start countin. i had two girls started 12/12 from seed on my last grow, and it was highly disappointing, only about 1/2-3/4 from each.

well if you did something like sea of green and you put all your cuttings in like an aerogarden till they rooted and stuck them under 12-12 you could pull a great yield and not have to worry about the height of the plants or waiting on them to veg, you'd only have to wait for a root system because you could cut branches that already have a few nodes, am i wrong?

from cuttings is about the only reasonable way to do 12/12 from start.

so does this mean the vote for the best way to get a quick yield is take clones root them and put them all on twelve twelve?

gogrow: i'm considering what you said about only a half to three quarters on each, how tall did they get and what kind of light were you using?

i use to do 12-12 from seed real good if your only growing for personall or limited space..or many other reason...yea the yeild is small..but i did 4 plants an yeilded 2.5oz dry total...showed sex in under 2weeks...imo its all good...peace az

how big were your plants

i only had two; two phenotypes of the same strain, flowered at 12" and finished with damn near no stretch at all, so they ended up at only 14-15". tall. it was fairly disappointing for the amount of time they took.

well how long did it take you to finish those plants?
cause the way i'm thinking is that if your plants will only get a foot tall, and they'll yield up to almost and ounce, why not just do sea of green and grow a bunch per cycle since they stay so small?

that is basically what i was doing on the current grow, but not 12/12 from the start. keeping under 24 until they are all about a foot tall then switching over to 12.

i didnt keep adequate track of the whole time frame, but they took about 95 days from start to finish, flowering was for 72 days.

that seems like a pretty long time to me, especially since your skipping and extended veg time, does that strain normally take a while to flower?

exactly, it was/is a long time b/c starting from seed on only 12hrs of light is like doubling your veg time. had they been started from rooted clones, they prob would have finished in about 75-80 days. but i have never grew that strain before, but watched the trichs closely, so i imagine that strain does normally take that long to flower.

you have to think about this, when you put a baby into flowering, it usually growths quite a bit before the buds begin to form, and correct me if im wrong, but indica grows once into flowering but begins budding faster? And this making the sativa the great choice because after going into flowering it actually grows alot more before showing buds?

I've heard that when a plant is dropped down to 12/12 from 18hrs or 24hrs it doesn't immediately go into flower but puts on a week or two of extremely quick vegetating because it wants to make as many bud sites as it can before flowering. If this is correct, then why couldn't you do this and before the flowers appear, put them back under 24hrs of 18 hrs of light, thereby keeping them in the vegetative stage and possibly tricking them into growing faster and bigger? Can anyone see a problem with this idea?

Sorry, that should read 24hrs OR 18hrs of light!

no pics of the progress??

That might stress it too much and cause it to be hermie. And sometimes when they are in 12/12 light for a certain amount of time it can take a really long time to go back to the veggetive stage. But i could be wrong.

I put 2 small clones directly into 12/12 to root. They are the cutest little fucked up plants you will ever see. I will post some pics after I have some coffee.

These guys were rooted in 12/12 about 3 or 4 weeks ago. When I put them in they were as tall as the edge of the pot. 2 different strains the indica dominate strain has made a bud about the size of a pingpong ball on the bottom thats rock hard and one on the top while the sativa dominate seems to be growing normally.
