2X 1000W - Questions on Ventilation/airflow

Hi there, i'm currently not at the area with the goods so I have no pics, but I'll try my best to explain.

I have a 12x9 room (Can be extended to 18x9) and I have 2 1000w lights , with something that looks like this for my exhaust , it's not that exact one , mine is a 250 watt going to the attic, and it works great. I'm going to settle for 2 6' Duct Booster fans to blow in fresh air, and I'm curious if this would be enough air flow?

Also, I plan to have both lights rotate all day , I was hoping to squeeze in 25-35 plants, what do you think?

Any feedback would be greatly appreciated,

Cheers, Cory.

The link is for a fan. What kind of lights are you using? Hoods, vertical hanging, cool tubes - what? There is the intake and the exhaust. We need more info.

hps 1000w x2

150w blowing in
both 1000w are hanging but will be switch to rotate from one end of then room to the other ,

You need more fan then that. I have a 1200-1400 cfm fan(its from a house ac unit w 8inch ducting on my 2 1000's and with them about 18 inches above the girls and having ac set at 79 my temps right at my plants are 82f-83f at soil everywere else is 78 79. W a oscilliating fan easy breezing the plants
