ahahha grannies tank. lmao thinking about injecting co2 and o2 at the same time.. it always cracks me up when ppl say your going to die from running co2
fuck after my tank ran out (stuck solenoid valve) i realized my monitor would read over 1000 ppm. this is of course when i have a few friends over. i get around 800 when it is just me and the ol lady.
Just make sure the fans are circulating air at floor level. co2 can pool in dead spots if you're not careful. I have one of the small vornado fans that sits on the floor aimed in a circular flow pattern around the tent.
