Light Times

I have OG Kush seeds (original, no flavoring), and i just want to get some opinions on the best light times for my plant. what do you suggest for the lighting times for growth and budding?
i dont have as much space as i would like, so im forced to either start early flowering or to train the plant.

I Suggest 24/0 for fastest vegging and flowering of course the almighty 12/12 .

just go with the standar 18/6 for vag and 12/12 for flower

if its a fem seed make a nice little ScROG screen and LST that sucker to fill up the screen.

" im forced to either start early flowering or to train the plant."
That tells me your grow space is vertically challenged. You need to flower soon or risk having your plants grow into the light.
Instead of flowering early I would just top the plants. That solves your height problem and opens the plants up to many more bud sites.

So, keep vegging at 18/6 or 20/4 and top them suckers. You should be able to have 2-4 main colas instead of just one. Flip the lights to 12/12
when the plants are about 50% as tall as you want them to finish. If you have 5 feet of clearance you need to be at 12/12 when the plants get
30 inches or so. Figure they will about double in height during flowering as a general rule of thumb.

Good luck, BigSteve.
