600W or 1000W HPS's?

I want to grow a lot of pot. Not worried about electrical costs. Have 6 foot from floor to ceiling. Will be using a DWC bucket system with the buckets on the ground. Should I use 600Ws or 1000W HPS's? Why? Any words other words of wisdom?
Thanks for the time,

6 foot doesn't buy the space u need for 1000w. I think you need at least 8-10 ft ceilings for those. Unless you plan on using cooltubes and above-normal cooling. Then maybe u could get away with the 1000w, if not stick to the 600w, they are suppose to be best lumens/watt I think. 2x600w is always better than a 1000w IMO. And if you get 2, you can run dual spectrum during both cycles for improved results.

What if I have air cooled light but not cool tubes. Sun Systems with a fan. 1000's then? Thanks for gettin' back.

what dimensions, in feet, length, width, 6 ft high you said? Attic, basement...basically how cool it stays has a big impact on what kinda light you can cram in there.

It's in a basement in Michigan and winter's coming up. The room is 20 ft by 8 ft.

yeah you can get a 1000w down there no problem. How many plants you looking to grow?

Im using a heater to keep my temps warm enough in the basement. No worries with the heat. I've placed my hand within 12" of hood and heat is not an issue. Intensity, however, is another story. 6'x8'x7'tall room. 60cfm venting perhaps. Humidity drops when 1000w is in use. Got curled leaves on my babies with the 1000, but the adult seems to luv it. It wasnt heat. Best of luck to ya.
