so when someones doing 12/12 from seed with a sativa, does day 1 that the light gos on from the seed being planted in the soil count as day 1 of flower? like say a strain needs 60-70 days to flower, is that the time it would take to do this form the seed touching the soil?

No. The plant will grow in a very condensed vegative state before showing the first flower. Look for the hair on the 21st day from seed. Then start your flowering count. At that point, be guided by Trichomes as to when to harvest.

 
True , but ther eare way's to shorten that 3 week period.
With 'pure' Sativa's they might take longer than 2 weeks , so a indic /sativa crossing is better suited if it comes to showing sex fast.

i have 2 plants that are 12/12 from seed (bagseed), obviously an indica-sativa hybrid, that sprouted on 5/5 and today i pulled 1 of them because it showed male flowers. day24. the other has not given a clue yet, which makes me think it might be female.
it's about 6 inches tall and on its 5th set of leaves.

i prolly won't try 12/12 from seed again, but it may still surprise me, i hope

anyway i guess i still have the 2 month flowering period to go

why wouldnt you do 12/12 from seed again? you see the yields some of these guys pull? some are better then guys growing 6' plants in a 5 gallon pot...if you want a short stout plant with a nice single cola this is ur way, if you wanna be overgrown and have huge plants then you might wanna veg for 2 months....but i saw a guy on here who was getting 5 ounces per plant on a 12/12 plant...just takes practive and time...

I do on occasion go 12/12 from seed. Granted your overall yeild will be a bit less HOWEVER it's finished 30 days sooner give or take! Do it. Different sativa's as well as different hybreds will show sex differently, there is NO set time they'll show...just be on the ball and keep an eye on em!!

I'd love to see someone who has been running a setup for at least a year, and knows the room relatively well, and knows what the average yield is to switch over to this method, and see what the new yield is.

that would be a great comparison

Even if yields were slightly smaller using the 12/12 from seed method, that would still make me lean towards going completely 12/12. You have to take into account that you are not using a veg room, and your plants are finishing earlier (2-3 weeks if I understand correctly, maybe a bit more).

I'm sure after some time has passed, if people like Atmosphere keep at it and keep furthering their research, strains will appear that flourish in this type of grow and techniques will also help to improve the yields, etc.

My biggest concern honestly is the potency. Yield, you can improve with different techniques, but potency is something that you cannot part with. Anyone have first hand experience with smoking both types of buds? 12/12 and regular?

Thanks, awesome thread!

bud is bud which all stem from genetics that are unchanged by running 12/12. the plant is mature at the end of its cycle whether it had veg time or not.
 
cobain there is a thread on here and the guy has been growing like this for a while...i will try to post the link....try this....atmosphere is the pro at this...L33t is the shit too..the results are proven...well sorry looks like you read about atmosphere...as far a potency no way...there are guys on here that grew out of a shot glass and ended up with about 1/4 ounce and they said it tasted just as good as the stuff the vegged for months...potency was the same also....i have 5 12/12 right now so in about 3 weeks i will let you know...lol

Thanks for the links and information guys, some well deserved rep coming your way.

I wasn't sure if the different light cycle would affect the potency. I wasn't sure if cannabis needed to reach a certain growth point, to perform to it's maximum capabilities. Apparently not - good information to know, thanks.

I will be starting a new flower room and may throw a few seeds starting off in 12/12 into the mix. See how their yields compare with a clone started at the same time, given a week or two veg time.

Thanks a ton for all the info guys, great thread!

a clone is the age of the plant it was taken from not the age of the cut itself...the comparison wouldnt really amount to anything




edit: since the clone is taken from a mother plant it is already mature which is not the case with any seed plant

I am going to compare the following, side by side, dropped into the same 12/12 flower room on the same day:

Plant 1) The seed started from 12/12. As soon as it pops through the peat pellet.

Plant 2) A clone given one week veg time after rooting then flipped to 12/12.

I'd like to place both of these in the same room, and see what happens.

My only concern is when you start off a seed in 12/12, seems you spend 2-3 weeks vegging anyway, so why not veg a mature clone, rather than an immature, possibly male seed plant?

Seems like the turn around time is 3 months from start to finish using the seed --> 12/12 method. Isn't this the same turn around time if you were to clip some clones?

I am not in anyway trying to discredit ANYTHING you guys are doing, what you are doing is fantastic! I am just bringing up random points that pop into my stoner brain, and eliminating my problems with this system one by one, so I will have all the information needed to make an informed decision if this would be feasible for an entire 10 x 10 room or something.

You guys are great, thanks a ton for all the info!

if you count the rooting time the clones are only ahead by 2 weeks if that but the major difference is clones are already mature. seeds arent, therefore your comparison isnt really a comparison, just a side by side grow of seed and clone under 12/12

Before the time I started using seeds directly on 12/12 I always used setups with clones . They ar easy to obtain overhere. Rooting clones is done on a massive scale. Especially in those days people in holland completely forgot how te grow decent plants from seed.
Once I started testing the 12/12 from sed method ( reported on overgrow) I yielded far more than I ever did with the clone setup . The extra 2 weeks taken into account the seed method still outyielded the clone method .

Very important is you can start a lot of seeds in very small pots ( 0,5 liter ) in a box with fluros, to do the first 3 weeks. After that transplant the females to your flowering room . this way you can always have flowering plants in you flowering room thats always on 12/12 .

With my current grow I started seeds directly in one large amount of soil to test how tall plants started on 12/12 can become.

pretty big it turns out , over 3 feet tall for an Indica /Sativa crossing.
