uh wow id give them way more light then that your buds wont be big and fat with cfl's its just not enough for them you'll have light fluffy stringy bud so if you can get a HID HPS is recomended
done right cfls can create decent nugs. just not in as much of an area that an HPS can..
youll see alot of growth in your plants before you see nuggz, the new 3 weeks have alot in store, rough estimate of 3 weeks before you see decent clusters of calyx's aka "Buds"
