help with plants plz

hello fellow stoners

my plant is about 14inches now, and i was thinking if i should switch it to 12/12 now. its been on 18/6 since it was a seedling. aldo i dont want it to be very big, so would it be possible to switch it to 12/12 at this time?

...sure can...i've flowered 2.5 " cuts succesfully...

If the plants are at 14" now, you can expect them to be about 28" at the finish.
