14/10 @ last two weeks of flowering?

[knna]

Im a bit confused: i thing some people answer about 10/14 and others about 14/10 (lights on/off).

I use both. 10/14 at the beggining and 14/10 at the end. And yes, i note it in the potency. Only slighty more yield than 12/12, but i think it improves THC %.

There was a controlled experiments: clones for same mother, grown at 12/12 and 10/14. The THC content of the 10/14 was 50% less than using 12/12.

I ve seen botanic studies wich show that more hours of light not only report higher yield (by more total iiradiance), but it affect to how the growth is distributed: more hours produce more carbon fixation to flowers and less to leaves and stems.

I upload a pdf of a botany study about (performed with similar plants to cannabis in photoperiod responses).

Harddon has a few posts where he recommends switching over to 14/10 to increase potency and production.

To try the theory out for myself, I went ahead and switched them 2 days ago and noticed quite the spurt in the buds.

Now granted it's a bit biased because she was in veg only 1 day prior to that so it could be she just had a lot of energy she was saving for the buds and decided to inflate like a beast.

I'll be sure to try this again on my next grow for some proper results

im at that point now. am willing to try but i have new clones in there too.
how will 2 weeks of 14-10 then back to 12-12.
any thoughts?

Hey guys, I have never tried this before but I have a firm believing that this guys right. THC forms in the dark, when your lights are off the THC is building, so giving it 2 more hours of darkness I guess would make for a more potent smoke, I must try this some time!!. T3ch , you think you're going to give this a go on your first grow?

the video link above states 2hrs longer of light so 14hrs of light and 10hrs of dark and to start the flush period at 5weeks.

i think i am going to try it... i am now at 5weeks and hope for the best, but i wish i was able to do a test

Bro that is so off!
Don't do that.
Flush 2 weeks before the buds finish.
And if you run it at 14 hours of light, it can start to veg again.
Half this thread is so far off it's scary. lol
I would never risk fucking up my yield after all that time . To maybe get more thc. Which I don't believe anyway.
Prove me wrong.
But I won't be trying this.:thumbsup:

J-whattup. your hushmail is full. i tried a couple of times. hope everything is goin smooth now!?! :thumbsup:

Big mike from advanced nutes talks about it too I would figure that it would give you overall more weight but he also said it can take an extra week to finish. I have never tried it I have done the reverse of that after 50 days in hopes of getting the trich to finish changing because it was a 70 day strain that I wanted to finish in 60 I ended up getting to pull it 6 days early.

in the vid he says with some strains you can go up to 14/10 at the last two weeks. I know what you mean it would be risky, maybe 13/11 for most strains?

It's possible, but like he says in the vid some strains can do 14/10, I would probably play it safe and do 13/11.
