Since we seem to be cross posting...Here is my reply from the other thread:

Well, don't know about you but that ain't my goal in the least. I am looking to improve on the plant's natural environment, not replicate it. I don't want to grow indoors for 5-6 months. I want to finish in 3 or 4. As well, anybody growing hydroponically is not replicating the plant's natural environment, since cannabis doesn't grow in a nutrient rich lake in nature.
12/12 from seed has many benefits, such as higher female ratios (reported by numerous growers upon switching to 12/12, and that being the only variable changed)
I have not heard this.
Also, the plants root structures are able to develop much more thoroughly during the dark period. There are also numerous reactions that occur in plants only during times of darkness.
Cannabis is a C3 plant. Photosynthesis occurs during the lighted times and it does not need any dark period. The more light the plant has, the longer the period of photosynthesis.

For instance, I grew 12/12 from seed with AK47 X Soma #10 and it did not flower for over a month, but it also didn't grow very much at all (due to lack of light, which equals short time for photosynthesis). So, I didn't save any time (one reason why some folks try 12/12 from seed) and I really screwed myself on yield.

Another grower I know did 12/12 from seed with Northern Lights and it started flowering right away. His experience was low yield and since the plants flowered before reaching maturity (alternate nodes), he described the high as much lighter and shorter than his mature flowered NL's. <shrug>

Since unless you are growing on the equator there isn't any place where 12/12 through all phases of the grow is natural, the view that this is replicating nature is false.
