The 12/12 is a pretty hard and fast rule, not often debated and more research needs to be done for sure. I've seen YouTube's that say after the 4 week on 12/12 you can go 10/14 with no problems but others say you risk ReVeging the plants...

I never had the balls to switch the hours during bloom as I have so much vested by that point. If I were to do it I probably would start the bloom at 10/14 from the beginning...

Nice topic, I look forward to the responses...
ZZTops Reviewed by ZZTops on . 10/24 for speeding up BLOOMING! hey folks, i have a very simple question but i need an answer from someone who has experience on the subjeck. I got 4 plants flowering in the 4th week now and i am considering to reduce the schedule from 12/12 (day - night) to 10/14 to save some time. Will it speed up the maturation of my plants and if so will i have any side effects? Rating: 5
