Atmosphere from ICMAG(was it ICMAG? i forget) stands by 12/12 and only 12/12

others followed suit to grow decent sized plants

The last picture is Atmosphere's
There's been loads of threads on here about 12/12 from seed. Most experienced growers won't recommend it and atmosphere himself (yeah it is icmag) admits it has it's downfalls and only has a couple of specialised uses that he himself only uses with specially chosen strains. I read through most of the icmag thread and there were some people who had success with the method, giving decent yields of around an Oz however the majority got less than 1 oz per plant (some much less, a few around 5 g) and none of the lengths of grow were substantially less than if you'd vegged for 4 weeks first. It seems the strain is very important and yields are better wiith mostly sativa plants which grow naturally in conditions that are close to 12/12. Don't expect this method to give you as good a yield as you'd get if you'd vegged till maturity, don't expect the bud to be as potent and don't expect it to be smokeable more than a couple of weeks earlier. If you're growing an almost pure sativa in an area with low height then 12/12 from seed might be worth trying, anything else I wouldn't bother. JMO
