12/12 From Seed: A Different Way To Grow

[bombadil.360]

oldweed, I also think the plant is a bit far from the light source, it looks stretched.

if you have another pot of the same size in which that plant is in, use it as base and place your plant on top so as to make it closer to the light, and see how she reacts after a few days.

keep the watering steady but light, and feed lightly too.

good luck!

looks a little small for 20 days. i have a plant at 2 weeks and some change. it's a little bigger than that one. but it's also in a much smaller pot. that pot holds 3 liters? it looks just like these 5 inch pots i have that hold like 1 quart maybe 1.5.

anyway my best guess is that your plant is too wet/cold which causes slow growth, let the pot dry all the way out one time before you water again. it won't die, after you water again it should have shown a lot of growth.

Thanks for the help and co tips.

I also think that the main problem is the light, ... I made a mistake not putting good light from the first day (for temperature problems).

I have enabled new intractores, direct cold air of street. Now I was able to focus down to the 25 to 30 cm, from the top of the plant.

Fearing premature flowering, with a small size, I modified to 18/6h for two or three weeks. After 12-12 shall begin again.

I have learned the error, lots of light, close focus, from day one, so that the plants develop better is required.

It's a good lesson, my next crop from seed 12-12, will have a lot of light from the beginning.


Thanks mates

WITH ANYTHING ABOVE 12-12 IS NOT 12 12 FROM SEED
once u do that ur not 12-12 from seed u have veg time...defeats the purpose..

I know, but is necesary.

Next time I return to 12/12 for try

hey i understand lol

somango47 (Positronics)

about 50 days from seed. 12/12 all the way....

This has been a joy to grow 12/12 from seed. This 'Evolution' product seems to have helped them get a bit bigger before they flip themselves which seems to be one of the main problems of 12/12.

The proof of the pudding here will be yield but it looks promising on that score.

Right now somango47 from Positronics are on my list of good 12/12 strains. Still a ways to go but I'm impressed with the simplicity of this grow so far..

 

[blueschato]

good work bro.
Very good info.

 

[Reg Dixon]

So will say that doing an auto 12/12 from seed is not the best way to maximize yield. Only got 64g from the Amnesia xxl. However the yield on the somango47 looks to be better.

The somango47 was topped and needed yoyo strings

final day

here is a pic that was taken recently. somango47 grown 12/12 from seed. Already had about 1oz worth of lower branches that had collapsed due to the weight of the buds vs the strength of the plant.

Doing a staggered harvest. Dry yield from the 1st plant was 150g + and it was the smallest of the three.

If you are going to 12/12 this plant I'd suggest getting lots of yoyo strings.

My guess is that the shortened veg period doesn't give the plants branches time to get enough N to support the flowers.
Could just be the strain though.

It took about 13 hours to read through the whole 144 pages...

I am here to tell that I have a 750w LED unit which I will use to straight 12/12 a bunch of seeds (26 Killing Fields, 5 Kolossus) in DWC buckets that can hold about 30l (8gal) each, five plants on each DWC. I also have 3 cuttings in the same DWC's that IN THEORY have had some veg, but in practice not (they're about 10cm or 4" in height). Dutch Master nutrients for most, one system running GHE only to see if these DM nutes are worth the extra money.

Reporting to this thread when I have some results to give out.

@v1 good luck with your grow. With that number of seeds sure you will do well. From reading through, seems one of the most one of most important decisions is whether to top them or not- depending on space, variety, etc. I have seen 12/12 go really perfect on untopped Crimea Blue which is really dense squatty uni-cola indica type branch pattern. Really good yields if correct strains r used. Bunched closely together it is a beautiful pattern.

After doing over 40 strains at 12/12 now, even I am still learning new information about this grow method. Some strains even if they are 100% Sativa are just not mean't for 12/12, while some Indicas that are close to 100% grow 3-4 foot.

All examples are in 3 gallon smart pots with atleast 600watts. These examples are of some Sativas grown 12/12. 2 on the left are Medi Haze by CBD Crew, they only yielded 14g each. The 2 Mango Haze I grew out last time from CBD Crew yielded nearly 4 oz's each from 12/12 so it really can be wide spread. The right one is Pure African by Sensible seeds which only yielded 12g. Aces Bangi Haze(100% Sativa) is by far the worst 12/12 I've ever seen. Grew out 4, all of which never reached above 5 inches tall with a combined yield of 20g total. I will post some more photos of the other current 12/12 ones I have. Some range from 2-3 foot, others like the green haze and oldtimer haze are 6 foot.

Got 256g + dry off 2nd plant. 12/12 from seed. 3 months and 2 weeks from seed to dried and curing in the jars.
Best 12/12 I've ever run by a mile and best one (for yield) I've ever had.

I will definitely try that strain. I noticed a bunch of different breeders provide that seed strain, which one was your choice? Many differences? I have another question. Are auto plants better for 12/12 vs fems? I ran 2 autos which didn't yield to great but that was years ago. Any other good 12/12's would be great.

do you have photos of this? a half pound dry from a plant that was 12/12 from seed is a pretty big claim to make...

 

[v1ru5]

I think regular cannabis varieties would outperform the auto's.

I am not planning to top, it's a bad idea for what I have done a lil bit of SOGing before myself.

Dr. King I just left a pack of Mango Haze back to my seedstash, I was wondering "this could be the bomb"... Should have gone with the feeling!

click the link in my sig for more pics and a whole diary where you can too discover how it was done.

and it is neither big nor a claim. it simply is what happened.

Man, I'm not trying to be a dick here, I'm really not. But I don't see a single photo in that link that shows a drying plant that yielded over 8 ounces of properly dried product. If I'm wrong, I really want to try Somango47, but I don't see how you could prove or disprove your claim anyways, so maybe it's a moot point. Either way, they look nice and you did a good job.

 

[ISM2]

The last pic in the grow journal is one massive-budding plant.
Is that the one that yielded 8oz?
