Well I am currently experimenting with 12/12 from seed.
Reason being simplicity and space. I do agree, a proper vegg cycle seems to premote more node sites. But downsizing to one cab, I need a 12/12 from seed setup.

My only issue with this grow is that you need a seccond light source to limit seedling stretch because the other plants are all 2 ft tall, and their light is up there to compensate.

I like the idea as a whole. Most people who are looking at this method aren't for profit growers and done need highest possible yeilds. Personal weed, for less effort is the primary and common goal I see when researching this method.

I compensate the lower yeild by rotating in a new seed every week, SOG style. you end up with 8 plants in various cycles of seedling to drying. This is my first time doing this and harvesting females, first batch of seeds yeilded all males. 10 seeds, 5 males, 5 dead.. Should see final results of the first inductees by late november.
