so no point thenIf you are venting the space then you will exhaust the CO2 as fast as it's produced (slowly).
Just the wallet. It is a complete waste. The air in there isn't stagnant, at least it better not be. The Co2 isn't going to just hang out in the bottom of the tent.It won’t hurt
Then it would just lay on the floor and never touch a leaf.Co2 is heavier than air it will get trapped in the bottom of the tent
