You need to keep your temperatures low(80 degrees max.), and airflow is necessary if you want a big healthy plant.
As for the lights you want at least 150w, be punctually with the lights you dont want to stress your plant. For veg.stage 18on 6 hours off. After you see your plant is healthy then turn the lights 12-12 for flowering.

NOTE: Your plant will double-triple the size in flowering stage.


P.S Read some growing guides and search the forums, that helps alot..:thumbsup:

Glad i can help

Cheers
