all respect to u fella but in my experience going 24/0 makes a hudge difference, the plants are shorter and grow much more side growth wilst staying short, more side growth=more bud sites, tho this is for the person who made the thread, ok buddy, ide start on 24/0 for 2-3 weeks then its ok just to switch straight to 18/6. u dont have to do it over a fiew days, just set ur timer to go 18/6 ul be fine. if ur using cfl for veg u will hardly notice the difference in amount of electricity used, if u were using 400-600hps or mh now then u might think bout cutting down to 18/6 from the beggining.
rite heres wot ive found works best, from seed
2-3 weeks in 24/0
2-3 weeks in 18/6 to get some upward growth as the plant will stretch a bit in the dark looking for light
and then the lovely 12/12, simple.
ide like to add this is all down to personal preferance!!!!!!!!!!! good luck all
