First things frist u need a decent growing medium CANNA COCO is fine, ask at you local grow store then you need some nutrient solution, I use IONIC GROW hard water(used in veg stage ie, growth)and i think u should atleast grow them up to a good hight like 2-3 feet,in the growth stage you're light should be on 24/0 24 hours a day or 18/6 18 hours light 6 hours dark.
When you're plant is in it's dark period is as to be totally dark no light at all as soon as light get's in the grow room it will fuck the growth patten and you're plant will start to re-veg and you should maintain this light cycle for at least 6 week's then when you think you're plant is ready and you think it's time to flower put the light's on 12/12 12 hours light an 12 hours dark and start feeding with IONIC BLOOM hard water wiht both the grow and bloom you should feed daily only if the plant need's it and you should flush every week.
And you should maintain the 12/12 light cycle for at least 8-10 week's depending on the weed and a some people wait for about 75% of the hair's on the bud to turn an amber colour....
GOOD LUCK M8.
