Yeah, I searched, and toxic levels of CO2 are 200,000 ppm. So please, Sativagrowing and everybody else can feel free to stick their heads inside their grow rooms when the CO2 is @ 1800ppm...
turtle420 Reviewed by turtle420 on . CO2 - how to? I have heard a lot of good things about CO2 -- So, I decided to mix one myself. My question is how do I use it? Do I just spray my home made CO2 into the plant? or do I have to add some water afterward? please advise. thanks Rating: 5
