yes of course i do. what i'm asking is exactly what am i removing from the air? i'm just saying it won't get musty from the dehumidifier, heat isn't an issue, and since i'm adding co2 and the plants put off o2 what exactly am i doing wrong? having it sealed keeps out bugs as well as smell. obviously you've been at this longer than I have but what is it that my air is lacking given my situation? i would apprecaite some experienced input as for what the technical benefit is.

thanks!
