is this true about flowering? time change to get bigger buds

I herd once the buding process start 12/12 turn lights up 23mins a day till u get to 14 on 10off and 2 weeks before harvest turn down an hour a day till 11 13off and u get bigger dense buds is this true?

I try not to fuck with the light times too much, id imagine changing it up like that all the time is pretty stressful for the plants and I dont want hermis

no............................12/12
unless you want re-vegging

dial it down when you want to start to force flowering to the point where you get the maximum hours of light + more importantly what the plant really looks for is the "downtime" so IF it will "maintain" flower production with only 11 hours of darkness then go for it...

most strains will all trigger under 12 hrs of darkness, but some others can be finagled with to "tweak" out the lighting schedule...

imo 12/12 is just plain simple and easy and the difference between 13on/11off is negligible... unless you have a long flowering equatorial sativa... then you can start to get all fancy with it...

but once it is "used" to the increase in time of darkness then better keep it consistent, otherwise just as scroglodyte said you DONT want it to reveg on you...

yea i have been going 12 12 on my white widdow for 4 weeks looking nice veg. for 2mths now i got 6ft monsters...i just put 4 white rhino into flowering today they went through 3.5 weeks of veg and there monsters 2 foot. and my time is from ground break. there ebb flow ww is soil
.

they will flower on 14 hours much the same as 12 hours, i didn't notice any difference i thought it might make them grow
more before budding but i couldn't see any difference
they will not re-veg unless they get 16 hurs, maybe 15 could work too for veg
i have never tried a 15 hour photo period so not sure what would happen on one

the theory is giving them more light will increase yield as you are increasing the overall photosynthesis while maintaining
enough of a dark period to keep them flowering , i remember reading something written by good old ed rothenthal about this
he said, he was aware it can be taken upto 14.5 hours on, and that it was common for plants outdoor in certain regions in the USA to only have a 9.5 hour natural dark period outside and flowering was induced with no problems with mainly indica varieties grown outdoor

the 12/12 is only a standard that will allow all weed plants to flower whatever their origins are it is said to be the best balance
i do not think you can achieve that much by playing around with the 12/12 standard since going below 12 to 11 or 10 hours on will decrease yield
going upto 14 will not increase it as far as i can see , maybe you will have different results

good luck
