Will switching from 24/7 to 18/6 trigger flowering?

Ok story goes:

I've come into possession of a couple of clones and have got them established, growing well. They are roughly 30 cm tall and about 6 weeks old atm. They will be my mothers. Thing is im thinking of switching the light cycle to (they have been on 24/7 from the beginning)24/7 to 18/6 but im worried it may trigger flowering, should i be?

Thanks for any help.

No should'nt make any differance to the veg stage but if possible i would leave on 24/7.I don't realy like messing the plants light cycles around but it should'nt make a differance.But make sure that the temps in the room stay has they always have been or this can make the plant turn.

no it wont... 18/6 is better in my opinion, cant tell a difference in growth but it helps with energy bills

Personally i love 24/0


Personally the 24/0 light cycle makes no sense to me. During hours of light plants multitask, they perform virtually every function at once. Even being under full light they can only absorb so much light to transform into energy so each function, including storing energy for use during hours of darkness, is only allocated a small amount of energy to use.
 
During hours of darkness plants stop multitasking and only perform their most important functions, growth is one of them and later while in flower THC production is another, but because the plant stopped multitasking and even though it is then running on stored energy the few tasks performed during the hours of darkness are allocated more energy to us during hours of darkness than during hours of light so those functions operate more efficiently.
 
That means growth occurs more efficiently during hours of darkness …. so just what is the logic behind taking away those hours of darkness when overall growth is the number one function the plant is performing at that stage of its life?
 
It makes no sense at all to take away the hours when a plant will grow the most efficiently and replace them with an equal number of hours when growth will receive a lesser share of energy and the plant will grow less efficiently.

I have always believed this... makes so much sense... plants are designed to have a no-photosynthesis period, thats why they store their energy in chlorophylls . they release this energy in the dark period.. actually i dont get how they do this under 24/0

wikipedia: Chlorophyll molecules are specifically arranged in and around pigment protein complexes called photosystems which are embedded in the thylakoid membranes of chloroplasts. In these complexes, chlorophyll serves two primary functions. The function of the vast majority of chlorophyll (up to several hundred molecules per photosystem) is to absorb light and transfer that light energy by resonance energy transfer to a specific chlorophyll pair in the reaction center of the photosystems. Because of chlorophyll’s selectivity regarding the wavelength of light it absorbs, areas of a leaf containing the molecule will appear green.
