Flowering @ 12/12. Then switching to 14/10

Ive read it a few times but never had any knowledge of anyone doing this with an actual diffrence.

So im currently in my 2nd week of flowering. all cfl.
anyways..ive read people talking about after a few weeks of flowering the cut it from 12/12 to 14/10 and was wondering if anyones done it and had faster flowering?

I know you get a smaller harvest im just asken for future grows.
cheers

Is that 14 on 10 off - or 14 off 10 on?

I'm guessing he means 10 on 14 off. I think I remember reading something about this. I believe you can harvest about a week to two weeks earlier but lose around 25% of the potential yield. I would highly suggest sticking to 12/12.

yeah i wouldnt try it unless i had a bunch of different plants to experiment on
