Indoor CO2 worth it?

[thephantomsfire]

I was thinking about adding CO2 to my grow box. I was just wondering your guys opinion. If so, what methods do you guys recommend? Thanks.

Unless you can run a closed environment, no external venting, then CO2 isn't worth it. I run CO2 in my hydro room but it has it's own A/C unit so I don't do any external venting or bring in any outside air. It's a totally closed room. If you are venting then the CO2 will just get sucked out as fast as you add it.

I use CO2, in a closed/sealed grow room and sometimes I wish I'm not. Reason being unless everything is going perfectly it's a waste of money. Regular air has a CO2 level of 400ppm and with a sealed room and adding CO2 you can triple that. However unless your light, humidity, air flow and nutrients (pH, EC, nute profile), strains, etc are ALL 100% there's no point in adding more CO2 really. You're better off getting all the basics perfect first, then once that's done, thinking about adding CO2 last.
