you can see where I'm at as far as growth stage in this link

or just look at the photo record in the link below...
I was noticing some smell, outside the grow room. I don't use an exhaust fan or filter, only a circulation fan.
I added a
black light to my setup, primarily for odor control. it's about 60cm or 2 ft long. it has done the trick. zero odor outside of the growroom, none in the growroom, unless I touch the plants, but that dissipates soon.
probably, your lights don't produce any UV. UV causes oxygen to attract an extra molecule making ozone, O3. Ozone eliminates odors.
it set me back about @$40.
