Co2 setup vented/unvented

So i usually run a fully vented system with HPS and CMH, i vent from one tent into the other and through 2 Inline filters to the outside, i have no extraction fans or filters inside my tents. (i grow in the attic which gets hold in summer and cold in winter)I have used Smart co2 bags, exhale ect * usually like over kill numbers in my tents and noticed a small difference. i know i am basically pumping it out the tent but I figure my girls will at least get a small benefit, mainly in greener looking plants.

So my question is A am i just wasting time with this, B if i was to use a Burner tent * aka set up another small tent as the first inline fit it with a burner only and then take the air from that and through my grow tents and out. would i raise the co2 enough to benefit in growth time and yield.


Lastly i am going to switch to LED very soon so i am wondering if i can get away with the temperatures doing the above but instead of venting out i would vent back into my burner tent creating a sealed system. maybe the burner would generate too much heat? there is no possibility for AC as its too noisy.
The other option instead of a burner is to make a mushroom tent and grow a shit ton of mushrooms
