Question on thr co2 bags or boxes

In my main flower room I already have a co2 burner,mini split, and 16k watts

My question is I just built a 10x10 flowering room so I can quickly throw new strains from seed I'm trying out into flower veg for maybe a week or 2 instead of growin 20/22lbs of a new strain that turns out to be poop so my question is how many of the my personal co2 boxes/co2 bags would I need for a 10x10 flower room to get near the 12/1500ppm with my burner in the other room?

Have you ever considered a CO2 tank and regulator? For a 10x10 I would go with a 50lb tank. The co2 bags aren't reliable as they appear to be.
