Splifman, is your light aircooled? If not you may want to look into that.
Yes, I have the proper hoods, but they are not air cooled at the moment. Here is the deal, the way I see it is I have three options. Air cool the hoods, vent the room, or do both. By doing both, I spend more money. So that is not somehting I want to do. Already spent so much. By cooling the lights, I still need to leave the door adjar with a fan blowing in fresh air, and teh smell is still an issue. By venting the entire room, I can use a carbon filter to take care of the smell and leave the door copletely shut to avoid light leaks.
That is why I am leaning towards just venting the whole room and putting the fan on a timer to allow for CO2 release.
Will 5 or 10 minutes every 1 or 2 hours be enough C02 enrichment?
