So out of all the info you were given this is ultimately all you wanted to hear.
This recipe is available online without the need to spark this conversation lol.
I will reiterate.
Co2 is only beneficial when all other avenues have been explored and dialed in.
Good luck on your grow.
See you In 2 months when your non ventilated grow room is exceeding 70% humidity and you’re worried your buds are going to develop botrytis.
Happy growing see you soon.
