600 watt vs. 1000 watt for new flower room

I am finishing out my new flower room, and I am having a dilemma. I was planning to use 600 watt HPS in the room, but one of my friends thinks I have enough room for dual 1000s. I am including schematics of the room, and any assistance is appreciated. The only change to the room so far has been replacing the 150 CFM with 300 CFM fans. With the inline cooling and 2 x 250 CFM fans and a 9000 BTU A/C, do I have enough cooling? I am installing CO2 this afternoon, so I can run the room a little warmer I suppose.

You do have enough room to use 1000's. It's up to you. Are you growing small plants or big ones?

The room is only 7' x 6' x 6.5'. I can't grow too tall. Dense! I'm looking for DENSE man!

I say 600watters. Save electric. It is up to you.

Do you really think that yeild will be that much more with 1000watters? they cover the same light footprint don't they..

your best bet would be 3-600's if dense nugs are your priority, you would use 200 watts less get a tad more light, have more points of light and be able to place the lights closer to the plants, plus with the 1000's there is really nowhere you could hang them without getting some major dark spots in the corners

1000 watters. look at my scheisse I have three rooms with 1 400 2 600 4 1000. 5600 PLUS WATTS and growing !!!!!!!!

it the lumens the bulb probuces that matters and i have put thosand watters in that small of a area it all about keepin it cool and there are many different kind of hoods for different light spreads i would go thousand watters for shure for flower

You can fit a 3 1000w lights

Or 2 on movers

Lmao I'm so stoned this thread has been dead

I posted this same question about a year ago (a little less than a year actually), and the overwhelming response from the majority of growers who know their shit on here was to get a 1000 watter if it would fit into my room/budget. Bottom line (according to several experienced growers on this site) was: BIGGER IS ALWAYS BETTER! more light = more plant. period.
