I have a similar layout: a tent inside a "sealed" room. I tinkered w/ yeast & sugar and citric acid/baking soda generation before buying a tank.My tent is in a sealed room my 5x5 tent is in a 12x15 sealed room but was given the thing for free so can’t hurt and only one way to see how it does
I have a co2 sensor, and while these improvised methods worked well, it's a lot more maintenance and not much cheaper than a tank.
You really need a way to measure the co2 level inside the tent; its the only way to determine if the bags are worthwhile.
