so i have a grow room that 2w,3l,6h and i broke up the inside space up just like the supercloset deluxe. i have a hole thats 2in and i have a fan right by the hole, you can see the blades spinning and its kind of acting like a intake fan. the fan is 6 in. i was wondering is my room getting enough co2 and if i make just another 2 inch hole that no intake fan will that air flow be enough?
