Light during flowering

I am in the sixth week of flowering with 12on/12off. Everything seems to going along just fine but I recently read that maybe I should be doing 6on/18off. I posted yesterday on this but I don't think I asked the questions correctly. Any words of wisdom???

Thanks

Keep it at 12/12. Why does everyone want to go against convention all the time? Trying to mock nature remember? Be kind of weird if the sun went down at 11:00pm and came up at 5:00am wouldn't it?

I have seen the sun go down at 11pm and come up at 5am but I have worked in northern Ontario. Some time in the north the sun never go's away for months but that is way up there.

12/12 works

That far north in Canada problem isn't a natural breeding ground for Marijuana. Not to mention 11:00pm - 5:00am is going to be after October. I'm not saying those days don't happen anywhere in the world, they typically don't happen in areas where Marijuana grows naturally and almost certainly not in the growing months.

I'm just saying that in the course of 8 week or 9 weeks the lighting on earth doesn't go from 18/6 to 6/18. That is pretty drastic.

As a relatively 'new' grower (I'm assuming you're on your first grow) you want to stick with the tried and tested 12/12, which works. In any case, you won't have a 'control' to measure against, how will you know if 6/18 produces better results than 12/12?

As far as I'm aware, 6/18 is used or can be used by growers growing extreme flowering Sativas or those Sativas that grow naturally in the tropics or close to the equator where the light is pretty much 12/12 most of the year round. They drop the 12 hours of darkness to 6 hours of darkness to try and speed up the 'flowering finish' time of Sativas that can take anywhere between 12-18 weeks flowering. These types of Sativas can take a very long time in flowering and can quite often alternate between fattening up existing buds and starting new growth. The lowered 'darkness' time from 12 hours can sometimes fool the plant into thinking that their life cycle is nearly over and speed up the process of producing seeds (or fat seedless buds) before they die.

For any other plants apart from these 'extreme Sativas' stick with 12/12.
