trap can you get a cheap CO2/ppm meter.? you kinda need one .. I think your idea would work. will it get 1500PPM? i dunno but i bet you could get it pretty high because of the build up in the cooler.
the cooler is the key to it working. Trap if the co2 levels are low after you know the levels. just add another bag.. and seal the lid.
