"p.s. carefull you dont blow your house up..."

CO2 will put out any fire you have so I wouldn't worry about blowing your house up. CO2 is NON-FLAMMABLE!!!!!!!!!!

I've never heard of anyone dying from 1500ppm CO2!!

Where does this shit come from?

CO2 is about 0.0314 % at sea level.

It will kill you if you have a HUGE tank malfunctioning in an enclosed space. Or cracked open like some ghetto grows.

You would need a HUGE fermentation vat going at balls out to even come close to killing you in your house.

Obviously youre not ready for CO2 and you should post some pics of some fat nugz growing b4 trying it.
