Ventilation help for a room build inside a garage.

Okay i have few questions and id appreciate any and all help. I built room inside my garage. The room is about 8' ×11' with 8' ceilings. Room was constructed with 2×4s insulated walls and above the ceiling i also insulated. And i used dry wall for all walls and ceiling. I have 4 1k lights with air cooled hoods. But right now i have 3 of the lights running until i pick up my 4th ballast up from my from boys house. Anywayd i would like some ventilation help. right Now i have 1 oscillating Fan and metal floor fan thats pretty strong. Well my friend who helped out building the room also set up my carbon filter which has a fan Attached to the top of the with 10" ducting, which runs from inside of the garage to a 10" hole cut in the middle of the ceiling of the grow room which he built a Styrofoam type box with 4 separate holes with ducting ran to each hood. Well i believe there has to be a better and more efficient way make this work. I recenty found 2 vents at the bottom of inside the grow room that go to the outside. Well those vents were covered with sheet rock and thought it would be a good idea to use this vents for fresh air to enter the room. im in the process of getting an a window a/c as we speak aswell. Also i would like to maybe in stall a vent on top of the garage roof which would suck all the hot air out of the garage. Anyways i asking for any all help or tips to help with my ventilation problems. Like what can do with 2 floor air vent that go outside. i would just like my room to have great ventilation. Use my filter and fan correctly and cool the hoods Better n correctly aswell. i want to buy maybe one or 2 more fans. Or whats the best n correct way to vent to room and garage.

I built a room in my pole barn a year ago...a little more than half the size. First your 4, 1ks sound like a bit much. Your cool tube venting has to create a pretty crowded ceiling. You ARE going to need an AC I believe unless your garage is already cooled, Your fans will move air but will not cool. Additional roof venting will help. What kind of temp range where you live? I have a floor vent and a filtered ceiling exhaust with it ultimately being ducted out the barn eves. My floor vent has a fan but its never on as i run it passive. I can because my room is tight and my exhaust fan also pulls the air in. I'll find the link to my build...maybe it will help.

The room now is on its 4th grow having traversed all seasons. Each came with its own issues...as you are about to find out. I am happy with my results though and yields continue to rise. Good luck.
