Homemade pop bottle c02

I am trying to find who made the home made pop bottle co2. I thought I bookmarked it but can’t find it. There so much great info here and than I lose it.

i made one, only using a single bottle with no lid though cause i didn’t have tubing etc. i eventually just threw them out because i didn’t want them attracting pests. i’d suggest using tubing and a 2nd bottle to filter the co2.

i wouldn’t worry about directing the co2 towards a fan or the plants etc, this video showed co2 levels to be the same at the floor and about a foot above (also showed you can reach almost 2200ppm with these homemade generators)
