no nutes for babies, gotta agree if you are this new co2 is not something you need to learn just yet, but if you realy need to and have to learn co2 then your room and co2 schedul needs to be a calculation only you can do, or buy a monitor so ppm stays at 1500 or lower. rember co2 can kill you so if you dont know what your doin you might not get a chance to learn it if you mess up.
