I've done 12/12 from seed. I think I got just under 20 grams from a single plant. Just one giant cola.

Here's the link. It was one of my very first attempts growing cannabis.

I did 14-10 lighting schedule.
I stagger my harvest.
The autos I got werent autos. So I left em in there with the new gear, photos, and had no ill effects. Definitely not true about one big main. Ime.
I cut clones in flower, kept in flower, yes they are one giant nug. The cheese/haze sativa dominant CK gear, is doing excellent.
I dont think anyone would know if I didnt tell em.

Long flowering sativas and sativa leaning hybrids do quite well even 12/12 from seed in my experience. But many of the indica leaning plants during my experiment did not do as well. They would have needed veg time to produce to their potential.

I just got a new phone so I dont have pics handy but with my og Kush x trainwreck seeds for example I still got over a qp per plant but like I said Some indica leaners only did 2 oz.

The bud was still all tasty and potent. But we all think there may be a better more complex high from flowering the plants once mature or older. 5-8 weeks veg.

Ed rosenthal stated longer veg equates to more potency in his book. I’m sure he was testing thc but what I’m feeling is more subtle and complex than just a rise in thc.

Also when comparing the same successful 12/12 grown clone with one having 30 day veg and one starting from 12/12. The vegged plant had much stronger branches and more leaves than the lesser more spaced out leaves and flexy whispy branches on the 12/12 plant. It needed stakes and ties to support all its branches but both plants yielded about 4 oz good nugs. We do not weigh trim, loose buds or smaller than a quarter size buds. That all goes into making coconut oil for edibles.

Hope this helped. I’m sorry I dont have pics handy but with the right strain/ pheno 12/12 can be very cost effective and successful.

As I grow new seeds perpetually I have gone back to an average 5 week veg.

Hey if ya got only one room. Do what ya gotta do.
My experiment has been the cheese/haze which is sativa leaning. So maybe thats why I'm having good luck, so far.
I dont have a base line to judge off of, ive only had autos before these. Woah what a difference. It was nice to be able to leave the light schedule and have different age plants in the same room, but the yield wasn't there.

Currently doing 12/12 with a sativa she's under 6in tall lol excited to see how much I get from this plant.
