hey guys, i am currently using one 2 bulb four foot floro for my three little guys, which range from 4 inches to 7 inches, i was just wondering if one was good enough, or if i should add more floros, and if they are good for the mean time, when abouts should i start adding more light.
any help is greatly appreciated

More light the better, especially when growing with florescents. I would add another light when she hits 12" atleast. Try to stay with "cool white" light for veg, keep it up around 6400K. Use warm bulbs for flowering somewhere around 3000K.
