Co2 Questions

I was wondering how soon to start giving Co2 to my babies. I will be using dry ice since it's simple and cheap. Not accurate by any means but I don't want Co2 filling my apartment.

duuuuuuuude im burning a propane tank, just started at my 4th week of flowering.. i feel ya, im really worried about carbon monixde(these are in my bedroom after all) and all the possible side effects of haven c02 lurken around.. who knows though

co2 is way diffferent than carbon monoxide

carbon monoxide will kill you faster than co2...
