He's right, and you definately want MORE lights. The more light the better. This is the most important thing- as much light as you can and then some! You will end up using those tube lights on the sides of the plants and you will want more lights above them. I'd have 3 or 4 of those (swirly lol) bulbs PER PLANT! Pot grows fast too you have to keep CFL's close and raise them a little every day.
