light time

my plants are now 2 weeks old from seeds. how long do i need to keep the light on for? does anybody have a light table for ever stage of the plants?

I use two schedules -
1. Vegetative growth - on for 18 hours & off for 6 hours (some people like to leave the light on for 24 hours for the first few weeks)
2. Flowering - on for 12 hours & off for 12 hours

There are variations on this schedule but this will give you a good guideline.

cheers mate. ill go set all my timers!

Yes, go with 18/6. 24/0 supposedly takes the plant longer to show pre flowers. Shorter light periods tend to give more females as well.
