I was at a local dispens.and I asked what he keeps his co2 at. He said ZERO! (iknow co2 is 300_350 ppm naturally), I asked why he didnt use a generator or bottle or something and he said that it wouldnt be organic if he did so he doesnt. Ive never heard co2 being disputed as organic or non organic. If anyone can shed some light on subject id appeciate it . Thx
