Yes the Co2 will help with the heat and stresses related, those bags are OK only if there hung over the plant, many will say there useless but they do something.. The sensor won't pick up much in relation to these as the outlet and air replacement will zero the calculafiins. Co2 is heavier than air. And maybe when fans are off it's more affecfive. Trail and error but yeah your on to simething, it's the first thing I considered when starting with co2 bags. Good luck on this journey
