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?
Hello HerbManual,
I have a simpler question; why would you think that cutting the photoperiod by 2 hours would help to make your plants mature faster?
Plant's use light during flowering to make flowers grow. Maybe adding an hour or two would help with flower developement, ie: increase size, hardiness, etc. But even that won't make them mature faster.

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...
am not the first to hear that reducing the light hours you speed up the proccess and increase yield, even if it's sounds rediculous. i would never dare to to that to the plants if i wasn't on a hurry cuz they are growing pretty beautyfull it's breathtaking!! but if someone has tried it and can guarantee it works then i am willing to try it. also is it normal in some point to see a slowdown in bud development? it's only in one of my 4 plants which they are all fed the same so the problem must be in the plant, even if it looks super healthy. i will upload a photo or two for you right now
12/12 is not carved in stone. It has been adapted as the defacto standard because it works on the majority of strains grown and it's simple. Take a pure landrace sativa and veg it for awhile, then switch to 12/12 and it will contiune to veg and not flower because where it comes from that's what it normally sees. It will flower when it wants to, and it is not all photoperiod dependent.
In flowering there are 2 important dark period amounts; how long of a dark period does the plant need to induce flowering and then how many hours of dark does it need to stay in flower. And they are usually different.
As to YouTube videos and posts on grow forums, look/read them for what they are and then try varifing that info against known science, either in a book or scientific paper or some reliable source (like university or college resource's online).

Hey Herb,
Now I understand where this idea is comming from. Thanks, you're right others have seen it too like ZZ. I would not buy into it unless I ran my own experiment, preferably side by side grow chambers or there was some science behind it. Hey Herb do it and see what happens. But what are you going to judge it by?
Your plants look good, I would not screw with the photoperiod.
The only way to insure uniform growth is to use clones from the same mother, and even then you can have some variation because location of the cuts or just how that one decides to act.
Continued good growing to ya.

thanks man your words are enspiring :D i decided not to mess with anything this is only my second grow and i 've been very disapointed from my first one it was a mess but i only used random seeds and spend about 50bucks total. not it's been a lot more complicated. the plant you see in the pic is a bublelicious strain it's autoflowering and needs only 6 weeks to mature or so i hope cuz the budz looks very juicy i can feel the oil in my hands when touching it's sterm.
p.s. i have reduced humidity to a max level of 45% (mostly at 39%) and am telling you the herbs are feeling up pretty good. cya
11/13 is where it's at. def speeds up flowering and yield.
