I would say it is okay, what I would really worry about would be how high temperature you get with the light on. For that size light, from GWE (below), looks to me like you would be okay. I would suggest giving it a go. There will be plenty of C02 available for the plant with 200 cfm pull through. Yes, air circulation is very,very important, and you may need two (or more) recirc fans, depending on the size.

Please help- Exhaust fan 4” or 6”
Just realized the one I bought might not be enough (AC Infinity Cloudline T4). My tent is 3x3x6’ with a HLG 300L 270w LED. My place is always cool 64-73 F and low humidity, no summer/heat waves which might help.
According to growweedeasy’s calculations I need 270 CFM w the carbon filter and this fan does 205, the 6” jumps to 402. I’m assuming at max setting.
Smell would be the other concern, will it scrub the space properly enough.
So should I go through a lot of trouble and $ (I’m not in the US so can’t just return them) upgrading fan+duct+filter or will it be fine with 1-2 circulation fans in my conditions?
