ur area is too big for just one 1000 watter but a lil small for 2......6.5ftx6.5ftx6.5ft. Not runnig C02 right now.
nah dude if he can manage the temps properly then i think 2x 1000s in a 6.5'x6.5' would be perfect.ur area is too big for just one 1000 watter but a lil small for 2......
yeaaah the heat is gonna be a bitch also..... I use a 4 x 4 light blueprint per 1000 watter hps....hell yeah you'll get more yield! optimal light would be 50sq. ft. per watt. right now you're running 23.67 sq. ft. per watt. adding another 1000 will put you at 47.4 sq. ft. per watt. that would be right around optimal light coverage. if heat isn't an issue, i'd go for it no doubt.

id say 3 600s..... and op we ment the heat from the lights..... I think u missnderstood4 600's would fit perfect and give you a great even light spread. You could even just get splitters to run 2 600's off each 1k (but you'd need more hoods)
