These guys are steering you in the right direction. For penetration, the HID is the balls. I've gone from a 400 in a 30" square, to twin 400's in a 48" square, now running a single 1000 in the 48" space. More is better!

If you must stay under the 500 watts, maybe grab a 400 HID, and hang whatever flouro's that you can at the sides. It may not be much, but you can relocate it from day to day, to spread the love around.

Check out some of DTR420's grows. He uses T5's alongside, topped with a 600 HID. Good stuff!

Thanks for the advice. How many plants were you able to grow with the single 400watt HPS and did you have any other light source? I can probably get away with the 600watt HPS since its only for the flowering. I would really prefer to be able to use more than one light so I could get light everywhere. Im not sure one 600 watt HPS light will give me a very good yeild with 5 plants. Thanks for the help and keep it coming.
