Hybrid sealed room

Hi guys I have a room I wanna use fresh air instead of co2 scrubbed of course . my lights are not vented but my room can hold required temp with ac I have , my question is im trying to add fresh air while exhausting it but I don’t wana suck out all my ac as well have u guys had experiences doing one of these systems?? Having hard tine finding ratios etc I believe it’s called a hybrid sealed room system

You find the balance. Don't pump the outside air in at such a speed. It'll negatively impact the grow room environment.

Give the AC enough time to cool to your target temps. While removing and adding the right amount of fresh air. Trial and error until you get the balance.

Usually the environment in the room where the grow room resides is conditioned first. Then its moved through the grow room.
