Just remember this, your gonna need some fans. The 600 is a GREAT set up. I've used the Lumen Ace and Future-Brite. Future Brite is the choice of many. You gotta have that hood your going to use vented.I vent 2 pro ultralite hoods with 1 465 cfm fan.It runs more than it should with the days being so warm.Temps stay 78-82,depends on the temps outside,whether it runs long or short periods. Don't get junk for ventilation. That is more important than the ballast!:stoned:
