"600 watt 80k lums lamp in a 6x7 or so area."

600 watts won't nearly cover that amount of space. You should ideally have 8,000 lumens per square foot in your flowering room. A 1000w hps puts out 140,000 lumens, which still wouldn't be enough for your grow space. 140,000/42 = 3,333.3 repeating lumens per square foot. Which is... NOT enough. I would suggest upgrading your lighting system and sizing down your grow room a bit... Heli's are looking for bigger heat sources then four or so HID's, they wanna bust the big boys, and as long as you pay your electricity bill.. You won't have a problem
