New Grower getting better circulation in a tent

[turtle360]

I like the idea of getting more CO2 available to the plants but it's a pretty big hassle and pretty impractical in a 3X3 tent. So, I thought there'd be enough CO2 by maximizing the air flow through the tent. At least it would get a natural amount. The tent is pretty typically outfitted, a main flap on each side, velcro closable and the 6 some odd ports for bringing cables in and out and what not closable with ties. I have a 4 inch Hurricane exhaust fan which meets minimum specs for moving the requisite amount of air in a 54 cu ft area.

What should I do to configure this thing for best flow? I've tended to leave all vents and ports open al fresco style. Maybe it would be better to close all but one vent, the one on the opposite side from the exhaust to create more pressure. Fan pressure? Open ventilation? How about bumping up to a bigger fan?

So, I made a remote reservoir for CO2 delivery that was pretty cheap and relatively effective (I think)

The set-up is in my Short Stuff test round#3 grow. Let me go grab a link...

It's an option...especially for small tents where it's difficult to hang any kind of
biomass-based CO2 generator out of the way of the lights.
