Can Smell Plant !!! Need better ventilation

Have a custom locker and is has a carbon scrubber than goes out a 3" x 3" vent. That vent then travels right up to the kitchen and you can smell the plant. Here is the pics of the venting in the back of the locker. What can I do to make the smell go away ???????

get a few of them replacement carbon filters for your cooker air hood



can get em at my local "Walmart" for 10-20$ a pice/packet, full of active carbon, use em as they are or cut em up and use the carbon to make a new DIY filter for your ventilation

that or make a quick fix and get a small bucket of Ona gel

or both

Not sure what you got.
I can see the fan in your photos, but not the carbon.

I like slipon's idea - replace the carbon. If you replace it often enough, you should improve your results.

Carbon scruber is in the locker. THe carbon scrubber probally gets rid of 80% of the tree smell.

Subtle point - but a scrubber is one that filters & exhaust inside your grow area. A filter is chiefly one that is one-pass flow that exhaust outside the grow area.
If it works for you, great!
