co2 and exhaust fan/?

my exhaust pretty much runs the whole light period to help w/ heat. it seems like the co2 is gettin sucked right out the exhaust cuz ppm is rarely over 800 and my buds didnt swell up at all like ive seen/heard about. my buds barely seem any denser than the last crop so something aint gellin any suggestions?

yes your exhaust is sucking it right out.
maybe try venting the hood.

im thinkin of getting a good ac, losing the whole cooled hood and exhaust for a couple open adjustable bat wing type hoods...then i think my co2 should be able to got my 12-1500 ppm range. any other suggestions?

If you seal the hood so the air flowing through it comes from the out side and goes to the out side.
Ad an ac. And depending on humidity levels. Either a dehumid or a humidyfier. To control humity.
Add co2. And you have no need for intake or exhaust.
Do a search on sealed room enviroments.
