if your using all clones "only clones"

veg with your light for 24/7 for two weeks and then switch st8 to flowering 12/12 thats for fastest results

or you can just normally 18/6 till the plant is the size you want it to be and flower but your plants grow almost twice the size when flowering so keep that in mind!
