I really should have done a proper diary of this 12/12 from seed experiment I finished a couple of weeks ago, just to show the U.K growers that you don't always have to stay on the well trodden path....

Anyway I done this with a Nirvana AK48 and was well pleased with the results.
The yield wasn't huge, but I knew that....but she did look mighty fine.

I switched her to 12/12 as soon as she raised her little head out of the rockwool cube. I grew her, hydro in a 1.5 litre pot with rockwool cube and clay balls.
I fed her Growth Technology for the first week then switched to Canna Aqua 2 part feed with Rhizotonic, Cannazyme, Canna Boost and Canna PK13/14.

She showed sex around day 18/19 and I flowered her for 56 days.
Wet weight on the chop was slightly over 4 and 3/4 Oz and dried to just over 1 and a 1/4 Oz..(who needs Low-Riders). Sorry I an't be more accurate on the weight as I only have regular kitchen scales...
She stayed very short and compact only reaching around 40 cm or so from the top of the pot and mainly grew only a single main kola with only two side branches coming off her.

The smoke was very nice and she smelled real, real nice.

Anyway here's a couple of pics for you all.

well done haggis, but trying that stunt with other types may have produced a non flowering plant... glad to see yours worked out.

so around 80 days from seed to weed... sweet...

njoy the fruits of your labour.

nice job, might try to now

Nice one Haggis, a good experiment though not one to repeat too often, after all more veg = more bud and thats what its all about innit

Wow, you finished at 15 inches with that much weed? That is awsome!

what makes you say that burst bud?
this below is good info...

The pigment phytochrome detects the presence or absence of light. This is how plants measure daylength.

When phytochrome absorbs red light with a wavelength of about 660 nanometers, the small protein that is attached to the phytochrome changes its folding. This changes some of its properties. For instance it becomes more hydrophobic and binds to membranes more easily when it is in the refolded state. Also it now absorbs light in the far red spectrum of 730 nm. When this form absorbs the far red light it refolds in its original form and the properties revert back to less hydrophobicity and it releases from any membranes it may of bound to.

Pr = red absorbing /660 nm
Pfr= far red absorbing/ 730 nm

Pfr reverts to Pr in darkness.

If far red light is given quickly enough after red light, phytochrome does not have enough time to affect cell metabolism and has no effect on the plant.

If the far red comes long enough after the red for the presentation time to be fulfilled, the Pfr is able to complete the transduction process and the far red light no longer cancels out the red light stimulation.

This is how critical night length is determined by the plant, the amount of time in darkness required to induce flowering. Cannabis is a long night plant therefore the night must be longer than the critical night length in order to induce flowering. In the case of cannabis the Pfr doesnt come for 12 hours (at least it dosnt in your closet) and now it no longer cancels out the red light stimulation and flowering is triggered.

just so you know mate there are some equatorial sativas that only get 12/12 when gropwing naturally and only flower when they are good and ready to.

Thanks for the "comps" guy's, she looked sweet didn't she.

@ stu… yes this is true.. only if the plant already has a signature of a different day/night length, if some canna plants are reared using only 12/12 it assumes that this is the day/night length of the growth phase so do not flower or take a very long time to flower. This is the reason we are told to start flowering at a certain amount of nodes… or am I wrong as per usual.

@ neo.. yup some equatorial sativas only get 12/12 this is why they take 6 or more months to mature not 80 days.

And as I said “trying that stunt with other types” from seed

This is why there are such plants as lowriders.

Cuttings in the other hand are a different ball game they are already mature plants so to speak. So flicking them into 12/12 once potted will produce what is called budsicles.

Why do you want to rush things just for the sake of 4 or 5 weeks veg

A plant flowered from seed will never reach its full potential yield or stone/high so by going 12/12 too early you end up with less yield and an inferior smoke

Therefore you'll smoke more than if you grew it properly so lose out anyway

Grow em properly and dont cut corners

Yes there are exceptions,some sativas you can go 12/12 from seed

Owd

That's amazing.
How much light did it have ?

I'm definitely a fan of challenging convention.

For myself, in a couple of months or so I should find out what 8 weeks' vegging can do compared to my usual 4.
8 weeks' vegging and LST.
If I don't get more than my usual 8 ounces dry I will be a tad bothered

yes compo amazing you get a crop with reduced yield that sounds great

Owderb, it is true what you say and I was aware of the reduced yield.
I just thought it was worth a go....see what happens an' all that. Personally, I wouldn't say the smoke wasn't really any weaker......it got me melted.

The reason's I thought it was worth a go were ....the seed was only £15 for ten, also I only got space in my hydro system for 8 so had two spare beans and very shortly I have to scale my set-up down from a drobe to a micro-grow....so thought why not..nothing to lose....but yes the yield was down in comparison to veging for a few weeks......but she did look real nice...1 nice thick single kola.

Compostverte, she was under a 125w Blue Enviro for the first week then she was under a 400w HPS.

thats pritty good.
1.25 from something so small and imature makes me think there good genetics. A cuttings crop as people have outlined would be an interesting proppersition. you could use bunkbeds at that height.

ive seen it done b4, along with a spraying with cultar. it never did that well though. mind you....it not dieing was a good enough result after that

Yes I know mate, I was surprised me' self....
She was real fat and dense it was un-real, could have been the CannaBoost that helped it along and obviously all the TLC I gave her.

12/12 from seed

I lie: 11/13 from seed

Jesus, half decent result but looks a bit lanky and airy. Not nice, juicy and compact like my AK.

Good to see others doing this. I have naff all head room and I dont veg any of my girls. Depending on strain you get some nice compact plants, quickly. Magic Bud is very good for this, they only reach 30cm and yeild just under an ounce each.

This might explain why my POG, Supergirl and Bubblegum took over a month to begin to flower, and didn't finnish properly.

Glad to see someone else has done a 12/12 from seed.
Most peeps think it's a complete waste of time......

"The Un-Educated" amongst us.....

Magic Bud 12/12 from seed, four weeks to go.

Well done, mate....looking nice.

Hi !

This is done by country where they have only 12/12 like Jamaica, Colombia, Cuba just to name a few.

Here is a Jamaican garden.



Respect
Claude

well done..it worked..BUT..you will never get the maximum production and developement and i am not talking about yield....a plant needs to go through a life cycle just like humans..ie toddler.. puberty.. adulthood .....that why no teenager has won a mr world[you cant build on muscle that does not exist]..4 weeks in veg will give you 10 times a better plant ..if a plant that germs in a area that gets 14/15 hrs darkness a day,it will not flower till it is a adult..grew weed in seyschells once and it still took 4/6 weeks before flowering[on equator.]..great job though.. just not for me[uneducated]
