I'm 100% sure about my claims. Activated carbon works, its in countless products that most people don't even know contains it. For mj though, it makes the smell not as potent and masks it. It does not completely get rid of it.

Depending on the strain, 4-6 plants, females, will put off a pungent smell, and will be hard to "hide" unless you don't mind the smell perfuming your place or exhausting it somewhere else.

When you say harvesting, do you mean drying or curing? When the plants are hanging trying to dry, the smell isn't as strong as it is while growing but there is a small amount of smell. Curing on the other hand means having it in a sealed container for a X amount of time. So, when the container is sealed, theres no smell. When you open the container to "breath" it, let fresh air back in and let the moisture escape, that doesssssss smell. While you 'breath' you jars for say 15-30 min's twice a day, the smell will perfume your place. It's pungent.
