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.
