You will need ALOT more light to grow MJ effectively...especially with fl's...also you need to keep them very close to the plant so you need a way to move it up and down...from what I have read and done...you will need about 2000 - 3000 lumens per square foot to grow effectively...

check this thread out....good old BobBong will show you the way and get you started :smokin:
