Definatley, and thats not even considering flowering. ur gonna want alot more for a good yeild. Im using 5 23 watt energy saving cfls, the coil styled ones. and thats just for vegging. thats probably gonna be for like 2 plants in the end. end you should keep them an inch away from the plant at all times. i also reccomend making reflectors. look in the grow faq for that. you can do it with soda cans. your also gonna wanna make sure its getting some of the light directed to the sides of the plant. You want it to grow out and up, not just out
