Alright I have a question. I have a 1500scf room that's completely sealed except for 2 air vents for the central a/c. I'm running co2, I have 2 6" inline fan with filters for more air circulation and smell. I live in Michigan so its getting cool at night and we are having really weird weather. My rooms gotten up to 93°. Now on the outside of my room it is about 60-65°. Its the other side of my basement. Would it work to just put a hole in the cieling and run a vent to just suck in the cooler air from the other side and out some screens on it to stops bugs. Does this seem like a good idea? Or will my co2 get wasted? An advice is welcome and very appreciated!
 
You can definitely setup another fan to bring in cooler air from other rooms, you have the correct idea to use filters. You don't want anything getting in your grow room that you did not specifically invite in. FUCK BUGS! I hate them.

As for the CO2, you should try to stop, or slow, all of your ventilation fans before deploying CO2 so you can get the air up to 1500 PPM of CO2. How are you controlling CO2 release? Regulator on a timer or are you using an environmental controller?
 
i pull air from under my house th cool my room i use an 8'' 500cfm duct fan from home depot to do this been doing it for over a year its hooked to the timer that runs my light its my understanding you can get away with higher temps with c-o2
 
I'm running the ppm4 co2 monitor. The fans are just for scrubbing the air to keep smell down, it has Bo effect on the co2. I just wasn't sure if that's bring in cooler air would be a good idea. I think I'm just going to get a duct inline to help push in the cooler air from the other room. I'm just trying to save a little on my central air bill. And make it so my house upstairs doesn't have to stay 60°late in the summer to keep the basement at 85°. Thanks for all the fast replys!
 
Yes you can run higher temps running co2 but 95°I is the Max before stressing the plants out. I want to keeps it between 85-90you while lights are on and 65-75 while lights are off
