CO² will do NOTHING if you are NOT using HID lights. Fluorescent lights do not produce enough light to help the plants absorb the extra amount of gas.

Check the FAQ there is a basic how to use CO² there. As for the scientific explanation and reason well I feel it would be a waste of time to type out the details.
