Is it possible to alter the light cycle in the flowering period to 24/12 ?

Short answer... NO

can you say "hermaphrodite"?

Have you tried this yourself? or are you just repeating what youve heard?
What if i was to do it just for the last 2 weeks of flowering?

r u saying have lights on 12/12 one day then the next day 24/0?......no

he means, give them 24 hours of light, then 12 of darkness, still giving them the same amount of darkness.

however it doesnt work this way... they don't go on one fact, like if its 12 hours of dark it's okay..

it needs 12h or less of light and 12h or more of dark to stay in the flowering cycle. The plant can sense these things.

you don't got the idea why to switch to 12/12 or??

it about imitating the sun in fall, red spec heavy, sorter light times longer nights, as so sun gets to the 12/12 point in nature about end of july cannabis starts to flower slowly. and the reason not to go much shorten then this is that if you put your cycle to 10/10 for example you may raise some attention that a boom of light is starting at 3 in the night all of a sudden also this cuts down on power that plant can tank up on during "day" so a 10/14 isn't to useful eight

Yeah well maybe you should pay more attention to the way you speak to me..you seem kind of condescending.

if you plan to cut back the light to 24/12 for flowering. what cycle would you be using for vegging 36/12?
