Is your room sealed? semi-sealed? not sealed? are you just adding a little to see if it helps? let us know what you are thinking so that we can better help.
If you are shooting for levels that truly work...1500 ppm or so you definitely need a sealed room, AC and probably a dehumidifier...if you have gone to that trouble then you should have a way of not only measuring ppm but controlling it. Guessing is not a good option if you plan to have your game at that level.
If you don't plan to take it to that level CO2 is not usually as effective as mucho air flow through the room. CO2 is just flat overrated until you take it to the level where measurement and control really aren't options. |
